3What this role really is

A junior web developer builds and maintains websites, working on real projects while learning core skills in web development.

4What you'd actually use

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

JavaScript (React & Node.js) Basic

Building and modifying React components based on design specifications, understanding how state and props work, and writing basic server-side logic for simple API endpoints.

Git (GitHub/GitLab) Basic

Cloning repositories, committing your code, pushing changes, creating Pull Requests, and resolving simple merge conflicts with some guidance. You'll follow our established branching strategies.

CSS / Sass Basic

Writing clean, scoped CSS or Sass to implement designs from Figma/Sketch mockups, using Flexbox and Grid for layout. You'll ensure visual consistency.

Vite / Webpack Basic

Using the project's configured build tool to run the development server, build the application for deployment, and install new dependencies. You'll understand the basic build process.

Jest / Cypress Basic

Writing simple unit tests for your components and utility functions, and following existing patterns to add basic end-to-end tests. You'll understand why testing is important.

Jira / Linear Basic

Updating tickets, logging your work, and moving stories across the board. You'll participate in sprint ceremonies like stand-ups and retrospectives, understanding how we track our work.

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 Approach for a New Feature Propose an initial idea to your Senior Web Developer, but the final approach is decided by them. You'll follow their guidance. Suggest and discuss multiple approaches with your team, then make a recommendation. Final approval from a Senior or Lead. Design the technical approach end-to-end, present it to the team, and get buy-in. You'll make the final call for your workstream.
Code Review Approval You'll review peers' code for basic style and obvious errors. Your 'LGTM' is a suggestion, not a final approval for merge. You can approve and merge routine code changes from peers, especially for smaller tasks or bug fixes, within established guidelines. You are a primary approver for all code within your workstream, responsible for ensuring quality, maintainability, and architectural fit.
Estimating Task Timelines Provide your best guess for simple tasks, but your Senior Web Developer will adjust and provide the final estimate. It's a learning process. Independently estimate small-to-medium tasks accurately. For larger tasks, you'll collaborate with the team. Lead the estimation process for entire features or workstreams, breaking down complex problems and guiding junior estimates.
Introducing New Libraries/Dependencies Always require explicit approval from your Senior Web Developer or team lead before adding any new external libraries. Propose and justify new libraries for specific problems, getting team consensus and a senior's final approval. Evaluate, select, and introduce new libraries or tools, setting standards for their use across your project area.

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.

Pull Request (PR) Feedback Cycle
The average number of review comments on your Pull Requests before they're approved and merged.
Target · < 10 comments per PR (after initial 3 months)

If your first few PRs have 20+ comments, that's fine. By month three, we'd hope to see that drop to around 8-10, showing you're picking up best practices.

Sprint Task Completion Rate
The percentage of assigned sprint tasks (bugs, small features) that you complete within the sprint timeframe.
Target · Consistently meets or exceeds 70% of assigned tasks

If you're assigned five tasks in a sprint and finish four, that's an 80% completion rate. We're looking for consistency here, not just one good sprint.

Bugs Introduced (Post-Deployment)
The number of critical or major bugs found in production code that can be directly attributed to your merged contributions.
Target · Fewer than 1 critical/major bug per quarter (after initial 6 months)

If a feature you worked on causes a critical login issue after launch, that's a big deal. We expect some mistakes, especially early on, but the aim is to learn and reduce these over time.

Code Review Turnaround Time (as Reviewer)
The average time it takes for you to review a Pull Request assigned to you.
Target · < 24 hours for non-urgent PRs

If a team member raises a PR on Monday morning, we'd expect you to have looked at it and left comments by Tuesday morning at the latest, keeping the team moving.

Proactive Learning & Asking Questions
How effectively you seek out knowledge and ask well-researched questions, rather than waiting to be told what to do.
  • You'll show this by asking specific questions like 'I tried X, Y, and Z, but it's still not working. Am I missing something in the documentation for A?' instead of just 'It's broken.' You'll also bring up new tools or techniques you've been exploring.
Code Quality & Readability
The clarity, consistency, and maintainability of the code you write, even for small tasks.
  • Senior developers will note that your code follows our style guides, uses sensible variable names, and is easy to understand without excessive comments. You'll get fewer comments in PRs about basic formatting or unclear logic.
Adaptability to Feedback
How well you incorporate feedback from code reviews and pair programming sessions into your subsequent work.
  • We'll see you apply lessons from one PR to the next. If a senior developer points out a better way to handle state, your next feature should reflect that learning. You won't make the same mistake twice, typically.
Team Collaboration & Communication
Your ability to work effectively with others, share progress, and flag blockers early.
  • You'll be active in daily stand-ups, clearly stating what you're working on, any issues, and what you plan to do next. You'll reach out to designers with questions about mockups before you've written half the code. You'll also offer to help others when your plate is clear.

7Would you like it

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

What people enjoy
Learning & Growth

You'll be excited to pick up new frameworks, understand complex patterns, and get better at debugging. Every day will bring new challenges and opportunities to expand your skill set. You'll probably spend some evenings tinkering with personal projects or reading up on new tech.

You'll jump at the chance to attend a workshop on a new React feature or spend an hour dissecting a senior developer's elegant solution to a tricky problem.

Building Tangible Things

You get a real kick out of seeing your code go from an idea to a live feature on a website. You'll enjoy the satisfaction of fixing a bug that was annoying users or implementing a new design element that makes the site look fantastic. It's about creating something concrete.

The moment a new button or form you've built goes live and you can show it to friends or family, that's what gets you going.

Team Contribution

You enjoy being part of a team, contributing to a shared goal, and feeling like your work makes a difference, even if it's small. You'll appreciate the camaraderie and the support system of working with other developers.

You'll offer to help a teammate unblock a small issue or jump in to review a PR, even if it's not strictly 'your' task, because you want the team to succeed.

What frustrates people
  • Vague bug reports with no steps to reproduce or browser info.
  • Spending ages debugging an issue only to find it's a simple typo or missing bracket.
  • Waiting for backend API endpoints to be ready, blocking your front-end work.
  • Dealing with legacy code that has no tests or documentation.
  • Last-minute design changes after you've already built and tested a feature.
  • Getting stuck on a complex problem and not knowing where to start looking for a solution.
What this role does not give you
  • Complete autonomy over technical decisions or architectural choices.
  • Immediate leadership or management responsibilities.
  • The ability to define project scope or timelines.
  • A perfectly clean, bug-free codebase to work with.
  • Guaranteed deployment of every line of code you write.

8Who you work with

This role directly contributes to the speed and quality of our web application development. Your work, though often small pieces, helps keep the development pipeline flowing. A good Junior Web Developer means less burden on senior staff for basic tasks, allowing them to focus on bigger, trickier problems. It also means we're building a strong talent pipeline for the future, which is pretty vital, if we're honest.

Inside the business
  • Senior Web Developers (for guidance and code reviews)
  • Product Designers (for understanding visual specifications)
  • Product Managers (for feature context and requirements)
  • Quality Assurance (QA) Team (for testing and bug reports)
Outside the business
  • None directly, but indirectly impacts our customers through the quality of the applications.

9What you need before you start

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

  • A foundational understanding of HTML, CSS, and JavaScript, demonstrated through personal projects, coursework, or a bootcamp.
  • Some practical experience with a modern JavaScript framework, ideally React, even if it's just from tutorials or small projects.
  • Familiarity with Git for version control – you should know how to commit, push, and create a Pull Request.
  • Basic problem-solving skills and a logical approach to debugging simple code issues.
  • A genuine eagerness to learn and grow in a fast-paced technical environment.

10What to practise next

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

Advanced React Patterns & Optimisation

As applications grow, performance becomes critical. You'll need to move beyond basic React usage to understand how to build highly performant and maintainable applications, using advanced hooks, memoization, and lazy loading. This ensures our apps stay fast and responsive.

Custom Hooks · Context API & State Management Libraries · Performance Optimisation (Memo, Lazy Loading) · Server-Side Rendering (SSR) & Static Site Generation (SSG)

  • This week: Read up on `React.memo` and `useCallback`. Try to apply them to an existing component in our codebase (with guidance).
  • This month: Build a small personal project that uses the Context API for global state management. Avoid prop drilling.
  • Month 2: Explore Next.js tutorials. Understand the difference between `getServerSideProps` and `getStaticProps`.
  • Month 3: Identify a component in our application that could benefit from performance optimisation and propose a plan to your senior developer.

Quick win: When you're building a new component, always ask yourself: 'Could this be more performant? Is there a better way to manage its state?'

Robust Testing Strategies

Bugs are expensive. As you progress, you'll be expected to not just write tests, but to design comprehensive testing strategies that cover unit, integration, and end-to-end scenarios. This ensures high-quality software and reduces the number of nasty surprises in production.

Test-Driven Development (TDD) · Mocking & Stubbing · Accessibility Testing · Performance Testing (Basic)

  • This week: Read an article or watch a video on the basics of Test-Driven Development. Try to apply it to a small utility function.
  • This month: Explore the `react-testing-library` documentation. Understand how to test component interactions from a user's perspective.
  • Month 2: Set up a simple Cypress end-to-end test for a login flow in a personal project.
  • Month 3: Propose a plan to improve the test coverage of a specific feature in our codebase to your senior developer.

Quick win: Before you write any new feature, even a small one, think about what tests you'd write to prove it works correctly. Try to write one unit test first.

11Staying current once you are in

What people here do to keep up
  • Regularly contributing to personal coding projects or open-source initiatives to keep your skills sharp and explore new technologies.
  • Participating in online coding challenges (e.g., LeetCode, HackerRank) to improve your problem-solving abilities and algorithmic thinking.
  • Attending local tech meetups or webinars focused on web development, React, or JavaScript to network and learn from others.
  • Following key industry blogs, podcasts, or online courses to stay up-to-date with the latest trends and best practices.
  • Seeking out and actively participating in code reviews, both as a reviewer and having your code reviewed, to learn from peers.
  • Taking advantage of any internal training programmes or mentorship opportunities we offer.
