1What this role really is

This isn't your first rodeo, but you're still keen to learn and grow. You'll be building and maintaining features for our web and mobile applications, taking ownership of smaller projects from start to finish. Think of it as moving from following recipes to creating your own, albeit with a seasoned chef nearby for guidance. You're a key part of the team, making sure our users get a smooth, reliable experience every time they interact with our products.

2What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

React & React NativeIntermediate

Building user interfaces and application logic for both our web and mobile apps, using existing patterns and component libraries. You'll be writing new components and connecting them to data.

Node.js & Express.jsIntermediate

Developing RESTful API endpoints for our backend services. This means you'll be writing server-side logic, handling requests, and sending responses.

PostgreSQLIntermediate

Executing queries, writing simple joins, and updating records in our database. You'll use an ORM (like Prisma or Sequelize) for basic data access, but also write raw SQL when needed.

Git & GitHubIntermediate

Managing your code with version control: branching, committing, creating pull requests, and resolving merge conflicts (mostly simple ones, with some guidance for complex ones). You'll be using GitHub daily for collaboration.

Docker ComposeBasic

Running and debugging applications locally in a consistent environment. You'll use existing Docker Compose configurations to get your development environment up and running quickly.

AWS (S3, Elastic Beanstalk)Basic

Deploying simple applications to pre-configured AWS services. You won't be architecting cloud infrastructure, but you'll understand how to get your code into the cloud.

Jest & React Testing LibraryIntermediate

Writing unit and integration tests for your own code to ensure it works as expected. You'll follow existing test patterns and contribute to our test coverage.

JiraIntermediate

Updating tickets, tracking your own work, and participating in sprint ceremonies. It's how we manage our tasks and communicate progress.

3What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing inWhere you are nowThe step above
Technical Approach for a FeaturePropose options; decision made by Senior Developer/Lead.Decide on the approach for small to medium features within established patterns; consult Senior Developer/Lead for novel approaches or significant deviations.Design the technical approach for complex features and workstreams; consult Lead/Architect on cross-cutting concerns.
Bug Priority & ResolutionEscalate all bug priorities; execute fix under guidance.Prioritise P2/P3 bugs in consultation with Product; independently resolve P2/P3 bugs; escalate P1 bugs immediately for team resolution.Define bug resolution strategy for a workstream; lead P1 bug investigations and fixes.
Code Review AcceptanceReceive feedback and make changes; final approval by Senior Developer/Lead.Provide constructive feedback on peer PRs; ensure your own PRs meet standards before seeking final approval from Senior Developer/Lead.Act as a primary reviewer for all team PRs; set and enforce code quality standards.
Tool/Library Selection for a TaskUse existing tools; suggest alternatives to Senior Developer.Select appropriate libraries/tools for specific tasks within established tech stack; consult Senior Developer/Lead for new tool introductions.Recommend and evaluate new tools/libraries for broader team adoption; lead proof-of-concepts.

4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

Story Points Completed
The number of story points (a measure of effort/complexity) you successfully deliver within a sprint.
Target · Consistently deliver 15-20 points per 2-week sprint.

If you complete a 'User Profile Edit' feature (8 points) and two bug fixes (3 points each), that's 14 points for the sprint. We'd look for that to be a regular occurrence.

Cycle Time (Ticket to PR Merged)
The average time it takes from when you start working on a ticket to when your code is reviewed and merged into the main codebase.
Target · Less than 3 days for small to medium tasks (up to 5 story points).

You pick up a bug on Monday morning, finish the code and open a PR by Tuesday afternoon, and it's merged by Wednesday. That's a great cycle time.

Bug Resolution Rate & Severity
How quickly you resolve bugs assigned to you, especially those impacting user experience.
Target · Resolve P2/P3 bugs within 48 hours of assignment; P1 bugs within 24 hours (with support).

A user reports a broken login flow (P1). You jump on it, get help from a Senior Dev, and push a fix within 18 hours. For a less critical UI glitch (P3), you get it done within 2 days.

Code Review Feedback Incorporation
How effectively and quickly you address feedback received on your Pull Requests (PRs).
Target · Address 90% of code review comments within 24 hours of receiving them, leading to merge.

Your PR gets 5 comments on Tuesday. By Wednesday, you've pushed updates addressing 4 of them and discussed the fifth with the reviewer to reach a consensus.

Code Quality & Maintainability
Your code isn't just functional; it's clean, readable, well-structured, and easy for others (and future you) to understand and modify.
  • Regularly receives positive comments in code reviews about code structure and clarity. Writes clear, concise comments where necessary. Follows established coding standards and patterns without constant prompting. Produces code that rarely needs immediate refactoring by others.
Collaboration & Team Contribution
You're not just a solo coder; you actively participate in team discussions, offer help, and contribute to a positive team environment.
  • Actively participates in sprint stand-ups and retrospectives, offering constructive feedback. Helps unstick teammates when they're stuck (where appropriate for your level). Shares knowledge during team syncs. Receives positive feedback from peers on collaboration.
Problem-Solving Approach
When faced with a bug or a complex feature, you approach it methodically, breaking it down, and seeking solutions independently before escalating.
  • Can clearly articulate the steps taken to debug an issue. Presents potential solutions and trade-offs when asking for help, rather than just 'it's broken'. Successfully resolves issues that aren't immediately obvious, demonstrating research and logical thinking.
Learning & Application
You actively seek out new knowledge and apply what you've learned to improve your work and the team's processes.
  • Proactively shares new techniques or tools discovered. Successfully applies feedback from code reviews to subsequent work. Shows demonstrable improvement in understanding complex parts of the codebase over time. Takes initiative to learn new parts of the tech stack when relevant.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy
Seeing Your Code in Action

You'll get a real kick out of seeing a feature you built go live and knowing that thousands of users are interacting with it. That direct impact is a huge driver.

When a new mobile app update goes out, you'll be checking the app store reviews or seeing analytics on the feature you contributed to. That's the good stuff.

Continuous Learning & Growth

You're always looking for new things to learn, whether it's a new JavaScript framework, a better way to structure your React components, or understanding how the backend works. You thrive on expanding your skill set.

You'll spend your lunch break reading a technical blog post or trying out a new library. You're not just doing the job; you're developing your craft.

Solving Interesting Technical Puzzles

You enjoy the challenge of figuring out why something isn't working, or finding an elegant solution to a complex coding problem. The 'aha!' moment is what you live for.

When a tricky bug comes in, you're the first to volunteer to dive into it, seeing it as a puzzle to be solved rather than a chore.

What frustrates people
  • Vague Bug Reports: Getting tickets that just say 'The checkout button is broken' with no steps to reproduce, screenshots, or error logs. It's like being asked to find a needle in a haystack blindfolded.
  • Mid-Sprint Scope Creep: Product managers adding 'one small change' to the requirements after the sprint has already been planned and started. It messes up your estimates and makes you feel like you're constantly playing catch-up.
  • Legacy Code Graveyards: Being assigned a task in a 5-year-old part of the codebase that has zero documentation, no tests, and was written in a deprecated framework. It's a real slog to get anything done there.
  • The 'Hurry Up and Wait' Cycle: Rushing to finish a feature only to have it blocked for days waiting on a backend change, an API key, or a design approval. It's incredibly frustrating when you're ready to go but can't.
  • Environment Hell: Spending half a day trying to fix a local environment issue or a problem that only exists in the staging environment, not on your machine. The 'works on my machine' excuse is real, and it's annoying.
  • Subjective Design Feedback: Implementing a design to pixel-perfect specification, only to get feedback like 'it just doesn't feel right' or 'can we make it pop more?' It's hard to code for 'pop'.
  • Time Estimation Pressure: Being asked for a precise time estimate on a complex, unknown task and then having that guess treated as a non-negotiable deadline. It's a recipe for stress and missed targets.
What this role does not give you
  • A perfectly predictable day-to-day routine; expect some curveballs.
  • Complete autonomy over architectural decisions (that comes later).
  • A role where you only ever build shiny new features; maintenance and bug fixing are a big part of it.
  • A quiet, isolated coding environment; you'll be collaborating a lot.

6Who you work with

Your work directly impacts user satisfaction and retention. Every bug you fix or feature you ship contributes to a better product experience, which in turn helps us grow and keeps our existing customers happy. Get it wrong, and you'll see frustrated users, support tickets piling up, and potentially lost revenue. Get it right, and you're a hero in the eyes of our users and the business.

Inside the business
  • Product Managers (they tell us what to build)
  • UI/UX Designers (they show us how it should look and feel)
  • QA Engineers (they try to break your code, in a good way)
  • Backend Developers (you'll work closely to integrate your frontend with their APIs)
  • Other Frontend/Mobile Developers (your immediate team)
Outside the business
  • End-users (ultimately, they're who we're building for)
  • External API providers (sometimes we connect to other services)

7What you need before you start

Not a wish list. The things you would be expected to already have.

  • A solid grasp of JavaScript (ES6+), including asynchronous programming (Promises, async/await).
  • Experience building at least one significant web or mobile application from scratch, even if it was a personal project.
  • Familiarity with modern frontend build tools (e.g., Webpack, Vite).
  • A good understanding of fundamental computer science concepts like data structures and algorithms.
  • Experience working in a team environment, even if it was for a university project or open-source contribution.

8What to practise next

Where the job is going, and what to do about it starting this week.

Advanced React & React Native Patterns

As applications grow, managing complexity in React and React Native becomes crucial. Moving beyond basic component usage to understanding advanced patterns like render props, higher-order components, custom hooks, and effective context usage is essential for building scalable and maintainable apps.

Custom Hooks · Performance Optimisation (memoization, lazy loading) · Error Boundaries · Accessibility Best Practices

  • This week: Refactor a small existing component to use a custom hook.
  • This month: Read articles on React performance optimisation and try to apply one technique to an existing feature.
  • Month 2: Explore a more complex state management library like Redux Toolkit or Zustand and understand its core principles.
  • Month 3: Lead a small internal workshop on a specific advanced React pattern you've mastered.

Quick win: Start actively looking for opportunities to refactor small, repetitive pieces of logic into custom hooks in your daily work.

Microservices Architecture & API Security

Our backend systems are evolving towards more distributed architectures. Understanding how to design, build, and secure microservices, and how your frontend interacts with them, will be critical. This means thinking about more than just a single REST endpoint.

Service Discovery · API Gateway Patterns · Authentication & Authorisation (JWT, OAuth) · Event-Driven Architectures

  • This week: Read up on the basic principles of microservices and why organisations adopt them.
  • This month: Pair with a backend developer to understand how our existing APIs are structured and secured.
  • Month 2: Take an online course on API security, focusing on common vulnerabilities and best practices.
  • Month 3: Propose a small improvement to an existing API endpoint's security or error handling.

Quick win: When working on a frontend feature, ask the backend team about the security considerations for the API you're consuming. Show interest!

9Staying current once you are in

What people here do to keep up
  • Regularly contribute to open-source projects relevant to our tech stack (React, Node.js). It's a great way to learn and show your skills.
  • Attend industry meetups and conferences (online or in-person) to stay current with new technologies and network with peers.
  • Complete online courses or tutorials on advanced JavaScript, React patterns, or backend development best practices.
  • Participate in internal hackathons or 'innovation days' to experiment with new ideas and tools.
  • Seek out mentorship from more senior developers within the team; they've been there and can offer invaluable advice.

10How the AI economy is changing work like this

Before we ask anything of you, here's what we can already say about AI and work of this kind:

The new skill this role is being asked for: Prompt Engineering & LLM Integration

Honestly, competitors are already using tools like GPT to draft reports in 10 minutes that used to take 2 hours. Developers who figure out how to effectively use and integrate Large Language Models (LLMs) will outproduce their peers significantly. It's not just a 'nice to have' anymore; it's becoming a core productivity skill.

We'll only ever tell you what we can actually back up. No hype, no scare tactics.

The ten Future Fluencies

Zavmo analysis

The credential is what you can do today. These are what keep you valuable.

A qualification proves you can do the job as it's defined today. These ten are what decide whether you're still the obvious person for it in five years. They're the capabilities employers are now writing into senior roles faster than people are learning them. Zavmo weaves them through whatever you study, so you come out with both: the credential and the fluency.

The highlighted ones are the Fluencies your role leans on hardest, from how Junior Web/Mobile Developer is actually changing. In about two minutes, the free confidence check asks where you stand on each of the ten. That's the whole check, and it's what makes the plan yours rather than generic.

Where it leads

Roles this leads to

12The team that's yours

No two people are taught the same way. This is one-to-one, not one-to-many.

Zavmo is a hyper-personalised AI learning platform. Twelve virtual tutors, each with a different way of teaching, and one orchestration agent that picks the right one for the moment. So every single lesson is shaped around you, your role, and the way you learn. Not a course everyone sits through. A conversation built for you, and no one else.

…and nine more, matched to you after your first chat. Meet all twelve

Start free and meet yours

13What it feels like

A conversation, not a course

Because your tutor knows your role, your projects and your last session, learning sounds like this. And it's different for every single person:

No two people run this the same way

A course is written once and handed to everyone. This is assembled around you, and keeps changing as it learns you. Five things it reads, and what each one changes.

  1. Your actual work Every lesson is taught against a live piece of your own work, not a worked example from a textbook.
  2. What you already know The first conversation finds your starting point, so you skip what you can already do and spend the time on what you cannot.
  3. The conditions you learn under Not a learning-styles quiz. The evidence does not support those. The dimensions the research does back, read once and used to shape the plan.
  4. How far you got last time It picks up mid-thought. The tutor knows what you said, what you struggled with, and what it asked you to try.
  5. Which tutor suits the moment Twelve of them, each for a different kind of thinking. The one who walks you through a first idea is not the one who stress-tests it.

See how you learn, free. Eight questions, no sign-up. A directional taster; the diagnostic inside Zavmo goes deeper and keeps adapting.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, a lot of development work can be repetitive or just plain tedious. That's where AI comes in. We're not talking about replacing developers; we're talking about giving you superpowers. Imagine spending less time on boilerplate code and more time on the interesting, challenging problems.

In this role, you'll be actively encouraged to use AI tools to supercharge your daily workflow. From writing code faster to catching bugs before they even hit a Pull Request, these tools are changing the game. We see AI as your co-pilot, helping you be more efficient and focus on the creative aspects of development.

Code Generation & Autocompletion

Use tools like GitHub Copilot to suggest entire functions, boilerplate code, and complex algorithms in real-time right within your IDE. It's like having an expert pair programmer sitting next to you, turning your natural language comments into functional code. This means less time typing and more time thinking about the solution.

Automated Code Review & Bug Detection

Integrate AI-powered static analysis tools into our CI/CD pipeline. These clever systems automatically scan your code for security vulnerabilities, performance bottlenecks, and those pesky 'code smells' before a human reviewer even sees it. This dramatically reduces the time spent on manual reviews and catches bugs that might otherwise make it to production.

Intelligent Documentation & Onboarding

Leverage AI to quickly understand unfamiliar parts of our codebase. Imagine asking an AI to summarise a complex function or map out dependencies. This dramatically speeds up how quickly you can get up to speed on a new project or understand legacy code, saving you hours of digging through old files.

Automated Unit Test Generation

Use AI tools to analyse a function you've written and automatically generate a comprehensive suite of unit tests, including tricky edge cases and happy paths. This helps us enforce good testing practices and increases code coverage with minimal effort from your side, freeing you up for more complex testing scenarios.

Increasingly, Prompt Engineering & LLM Integration and WebAssembly (Wasm) Fundamentals. These are the areas where the higher-paid, future-proof work is heading.

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Junior Web/Mobile Developer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

  • Searching and planning stay free. You only pay when you start learning.
  • Your credits are yours. Regulated, and they don't vanish when a subscription ends.
  • Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

This route runs to 1 national skill standard. That is a real journey.

Zavmo shapes a learning experience as unique as you are. It fits how you learn, your pace and the work you already do. Every step stays benchmarked to recognised national standards. That’s the plan for becoming a Junior Web/Mobile Developer: personal to you, and it still counts. The first steps are free.

Independent research finds well-designed intelligent tutoring performs nearly as well as one-to-one human tutoring: VanLehn (2011), Educational Psychologist.

Other roles at Level 3

Same depth of qualification, different job. Useful if the work appeals but this particular role does not.

Other roles in Technical roles

Stay in the field you know and move sideways rather than up.

If you leave this industry

The skills you'll gain as a Web/Mobile Developer are highly transferable. You could move into backend-focused roles, specialise in DevOps or Site Reliability Engineering, or even transition into Product Management or Technical Consulting, given your deep understanding of how software is built and delivered.
