3What this role really is

A full stack developer builds features across the front end and back end, taking a user story from idea to deployment.

4What you'd actually use

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

React.js Intermediate

Building and modifying complex frontend components, managing component state, and integrating with our backend APIs to create responsive user interfaces. You'll be working with hooks, context, and perhaps Redux Toolkit.

Node.js (Express/NestJS) Intermediate

Implementing and extending REST API endpoints, handling business logic, connecting to our PostgreSQL database, and integrating with third-party services. You'll be comfortable with asynchronous programming.

PostgreSQL Intermediate

Writing complex SQL queries for data retrieval and manipulation, designing and modifying database schemas, and optimising query performance. You'll also use an ORM like Prisma or TypeORM effectively.

AWS (EC2, S3, RDS) Basic

Deploying applications by following existing CI/CD pipelines, navigating the AWS console to check logs, monitor resource status, and understand basic cloud infrastructure. You won't be designing the cloud architecture, but you'll use it.

Docker Intermediate

Building Docker images from existing Dockerfiles, running containers locally for development, and understanding how our applications are containerised for deployment.

Jest & React Testing Library Intermediate

Writing comprehensive unit tests for individual functions and React components, and integration tests to ensure different parts of the application work together correctly. You'll aim for good code coverage.

Git & GitHub Advanced

Version control, branching strategies, managing pull requests, and resolving merge conflicts. This is fundamental to our collaborative development process.

5What 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 in Where you are nowThe step above
Technical Implementation Approach Proposes options, requires approval from a Senior Developer or Manager. Decides on the best approach for routine tasks; consults Senior Developer for complex or ambiguous problems before proceeding. Defines the implementation approach for complex features and advises junior team members.
Code Review Approval Cannot approve PRs; receives feedback. Can approve PRs from junior developers; receives feedback from Senior Developers. Approves PRs from all team members; sets code quality standards.
Database Schema Changes Implements changes based on explicit instructions; requires full review. Designs and implements minor schema changes; requires review and approval from Senior Developer or Architect. Designs and approves significant schema changes, considering long-term impact.
Production Deployment Follows existing CI/CD steps; cannot initiate independently. Can initiate routine deployments for features; requires peer review and manager awareness. Leads complex deployments, coordinates with other teams, and manages rollbacks if necessary.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Cycle Time
The average time it takes for a piece of work (a ticket) to go from 'In Progress' to 'Done' in our sprint board.
Target · Under 3 days, consistently.

If you pick up a ticket on Monday and it's deployed by Wednesday, that's a 2-day cycle time. We want to see you getting things through the pipeline efficiently.

Pull Request (PR) Quality
The average number of comments or requested changes on your code reviews before a PR is approved and merged.
Target · Fewer than 10 comments per PR, with most being minor suggestions.

You submit a PR, and after review, there are only 5 small suggestions for naming or a minor refactor, rather than fundamental architectural changes or bug fixes. This shows you're thinking things through upfront.

Introduced Bug Rate
The number of critical or major bugs that are directly attributable to code you've written and deployed.
Target · Fewer than 1 critical bug per quarter, and ideally zero.

You deploy a new feature, and within the next week, a customer reports a show-stopping error that breaks core functionality, and it's traced back to your recent changes. We want to minimise these.

Story Point Completion
The percentage of story points (our estimate of work complexity) you commit to at the start of a sprint that you actually complete by the end.
Target · Consistently completing 80-100% of committed story points.

If you commit to 15 story points in a sprint, we'd expect you to complete at least 12 of those. It shows good estimation and reliable delivery.

Code Readability & Maintainability
How easy it is for other developers (and future you!) to understand, modify, and extend the code you write.
  • Positive feedback in code reviews about clarity and structure
  • minimal follow-up questions from teammates when they need to work on your code
  • adherence to team coding standards and patterns without constant prompting.
Proactive Problem Solving
Your ability to identify potential issues, research solutions, and propose a path forward before escalating every little blocker.
  • When you hit a snag, you've usually got a few potential solutions or at least a clear question after some research
  • you're not just saying 'it's broken' but 'it's broken because X, and I've tried Y and Z, what about A?'
  • you spot edge cases or potential issues in requirements before coding starts.
Collaboration & Communication
How effectively you work with product managers, QA, and other developers, and how clearly you communicate technical concepts.
  • You actively participate in sprint ceremonies
  • you give constructive, helpful feedback in code reviews
  • you can explain a complex technical issue to a non-technical product manager in a way they understand
  • you ask for help when genuinely stuck, but not before trying to figure it out yourself.
Ownership of Features
Taking full responsibility for a feature from initial understanding through to deployment and post-release monitoring.
  • You're not just coding what's asked, but questioning requirements, thinking about edge cases, and making sure the feature actually works end-to-end
  • you're the first to spot an issue with your deployed feature and proactively work to fix it
  • you don't just 'pass the buck' once your code is merged.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Seeing Your Code in Production

You get a real buzz when a feature you've built goes live and you see users interacting with it. You're constantly checking the staging environment and then production, eager to see your work making a difference.

You've just deployed a new user authentication flow. You'll be checking the logs, monitoring user sign-ups, and maybe even trying it out yourself to make sure it's all working as expected. That feeling of 'I built that' is a big driver.

Solving Tricky Technical Puzzles

You enjoy the challenge of debugging a complex, intermittent bug or figuring out how to integrate two disparate systems. The more obscure the problem, the more satisfying the solution.

There's a weird caching issue that only happens on Tuesdays after 3 PM. While others might groan, you see it as a fun challenge, methodically digging through logs and network requests until you find the root cause.

Continuous Learning and Growth

You're always looking for ways to improve your skills, whether it's picking up a new framework, optimising a database query, or learning a better way to structure your code. You see every task as an opportunity to get better.

After implementing a new API endpoint, you'll spend some time researching how to make it more performant or secure, even if it wasn't explicitly asked for, just because you want to improve your craft.

What frustrates people
  • Vague Tickets & Scope Creep: You'll get Jira tickets that say 'Fix the user profile page' with no details, and then the requirements will change three times after you've already started coding. It's frustrating, but it's part of the job.
  • The Legacy Code Graveyard: Expect to spend time digging through 5-year-old codebases with no documentation or tests, written by someone who left years ago. It's not glamorous, but it's essential to keep things running.
  • "It Works On My Machine": This classic, infuriating problem will happen. Your code works perfectly locally, but breaks mysteriously in staging or production. Debugging these environment differences can be a real headache.
  • Pressure to Skip Tests: Sometimes, to hit a deadline, you'll be told to 'just ship it' and 'add tests later'. You'll know it's a bad idea, and you'll probably be the one fixing the bugs that come from it later.
  • The On-Call Pager (occasionally): While not a daily thing for L2, you might be part of a rotation where you get woken up at 2 AM because a server is down. Debugging critical production issues while half-asleep is not fun, but it's part of being a reliable engineer.
What this role does not give you
  • A perfectly structured, predictable work environment with no surprises.
  • The chance to always work on brand-new, greenfield projects.
  • A role where you'll be solely focused on one tiny part of the stack (e.g., just frontend or just backend).
  • A role where you're constantly innovating at the bleeding edge without any maintenance work.

8Who you work with

Your work directly impacts the speed and quality of our product development. When you deliver features reliably and with good quality, it means we can ship more value to our customers faster. You're a key cog in the machine that keeps our product moving forward, directly influencing user satisfaction and our competitive edge. Getting things right here means fewer headaches for support and a smoother experience for everyone.

Inside the business
  • Engineering Manager (your direct report)
  • Senior Full Stack Developers (for technical guidance and code reviews)
  • Product Managers (to understand requirements and user needs)
  • QA Engineers (to ensure what you build is thoroughly tested)
  • Other Full Stack Developers (for collaboration and knowledge sharing)
Outside the business
  • Occasionally, you might interact with third-party API providers if we're integrating new services, but this is usually managed by more senior folks.

9What you need before you start

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

  • At least 2 years of professional experience building and deploying full stack web applications.
  • A strong portfolio or demonstrable projects showcasing your ability to build functional, well-tested applications across the stack.
  • Solid understanding of core computer science concepts like data structures, algorithms, and object-oriented programming.
  • Experience working in an Agile/Scrum team environment, participating in sprint cycles and code reviews.

10What to practise next

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

Frontend Performance & Optimisation

User expectations for fast, responsive web applications are only increasing. You'll need to go beyond basic React and understand advanced techniques to ensure our frontend is lightning-fast and provides a smooth user experience.

Core Web Vitals · Advanced React Performance · Client-Side Caching Strategies

  • This month: Profile one of our slowest-loading frontend pages using browser developer tools and identify the biggest bottlenecks.
  • Next month: Implement lazy loading for a non-critical component or route in one of our applications.
  • Month 3: Research and apply `memoisation` to a frequently re-rendering component that's causing performance issues.
  • Month 4: Present your findings and proposed optimisations to the team, showing measurable improvements.

Quick win: Run Lighthouse audits on a few key pages in our application and identify the 'low-hanging fruit' for performance improvements.

Database Optimisation & Advanced SQL

As our data grows, inefficient database queries become a major bottleneck. Moving beyond basic CRUD, you'll need to master advanced SQL and understand how to diagnose and fix performance issues at the database level.

Query Plan Analysis · Advanced Indexing Strategies · Database Partitioning & Sharding (Concepts)

  • This month: Identify the slowest query in one of our backend services and try to optimise it using `EXPLAIN ANALYZE`.
  • Next month: Research and propose a new index for a frequently queried table that's currently performing poorly.
  • Month 3: Take an online course on advanced SQL and database performance tuning.
  • Month 4: Document your findings and share best practices for database query optimisation with the team.

Quick win: Familiarise yourself with your ORM's debugging tools to see the raw SQL queries it generates. It's often an eye-opener.

11Staying current once you are in

What people here do to keep up
  • Regularly contributing to open-source projects or maintaining personal side projects to keep your skills sharp and explore new technologies.
  • Attending relevant industry meetups, webinars, or conferences (we often sponsor these) to network and learn from peers.
  • Subscribing to technical blogs, newsletters, and online learning platforms to stay current with industry trends and best practices.
  • Participating in internal knowledge-sharing sessions, presenting on topics you're passionate about, or mentoring junior developers informally.

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Prompt Engineering & LLM Integration

AI assistants are quickly becoming indispensable for developers. Those who can effectively 'talk' to these models, whether for code generation, debugging, or documentation, will be significantly more productive. It's not just about using ChatGPT; it's about integrating LLMs into our development workflows and even our products.

  • Effective Prompting for Code
  • Context Windows & Token Limits
  • RAG (Retrieval Augmented Generation)
  • Output Validation & Hallucination Detection

Advanced Serverless Patterns

The shift towards serverless compute (like AWS Lambda) continues. While you're familiar with basic AWS, understanding more complex serverless architectures, event-driven patterns, and optimising for cost and performance will be vital for building scalable, cost-effective backend services.

  • Event-Driven Architectures
  • Lambda Cold Starts & Optimisation
  • Serverless Database Integration
  • Infrastructure as Code (IaC) with Serverless

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, software development has its tedious bits. But what if you could offload some of that grunt work to an intelligent assistant? Our team is embracing AI tools to make us more efficient, letting us focus on the really interesting, complex problems. This isn't about replacing you; it's about making you a superhero developer.

As a Full Stack Developer, you're constantly jumping between different parts of our codebase, solving problems, and writing tests. AI can be your co-pilot for a surprising amount of this. Imagine generating boilerplate code in seconds, getting instant explanations for cryptic errors, or even drafting documentation without breaking a sweat. It's about augmenting your abilities, not automating your job away.

Boilerplate & Test Generation

Use AI tools like GitHub Copilot or similar to instantly generate repetitive code. Think API endpoint handlers, data models, or entire unit test skeletons. It's like having a hyper-efficient intern for the boring stuff, letting you focus on the unique logic.

Smart Debugging & Error Analysis

Ever stared at a cryptic error message for an hour? Just paste it into an AI assistant (like ChatGPT-4 or Claude) and get a plain-English explanation, along with potential solutions or areas to investigate. It's like having a senior engineer on call 24/7 for debugging advice.

Accelerated Learning & Research

When you hit a new library, framework, or concept, ask an AI for a concise summary, code examples for common use cases, or even a comparison to tools you already know. Cut down your research time from hours to minutes, getting you to the 'building' phase much faster.

Automated Documentation & Communication

Nobody loves writing documentation, but it's essential. Use AI to automatically generate docstrings for your functions, draft clear summaries for your pull requests, or even help you write concise release notes. It frees you up to code, not just write about code.
