Junior developer with front-end experience

Founded in 2015, Tussell is a founder-led and investor-backed tech scale-up based in London.

Tussell's vision is to be the definitive source of market intelligence on UK government contracts. In a climate of unprecedented government spending, our data helps companies to win more public contracts by making better commercial decisions. Our competitive edge is expressed through the richness and reliability of our data, and as a result, over the last decade, we have become the market’s trusted source.

We strive to be a great business, and we’re also proud to make a difference along the way. The enhanced transparency that Tussell fosters makes the government more accountable for spending decisions. It also helps to make public procurement more efficient and accessible, ultimately improving value for money in public services.

Tussell has an entrepreneurial culture and is focused on growing profitably through customer sales, rather than relying on successive rounds of venture capital funding. We have a dynamic, welcoming team meaning we’re small enough for you to know everybody’s name.

Goal: We're looking for a junior developer with front-end experience to join the team maintaining our Ruby on Rails and React.js applications. This is a hands-on role from day one, working on the UI layer of a live, data-heavy product, with support and mentoring from senior engineers as you learn our specific design patterns and domain.

Frontend Development

Build and maintain front end code, including JavaScript using frameworks such as React components and Stimulus controllers, within our existing patterns

Work in our Rails views and partials, editing view templates and wiring up React components inside them

Implement UI designs using HTML elements and CSS, working from mockups, Figma files or written requirements

Fix bugs and make incremental improvements to existing views and components

Write and maintain unit tests for the JavaScript and webpage components you work on

Collaboration & Delivery

Collaborate with designers, product managers and other engineers to turn requirements into working UI

Participate in code review and collaborative Git workflows

Be willing to ask for help and pair program as you get going; we're investing in your professional development, not expecting a finished product

JavaScript fundamentals: You have experience with modern JavaScript, its ecosystem, like Node and Yarn, and how to work with its libraries and frameworks as part of front-end code

React practitioner: You have practical experience with React (we use React 19, functional components and hooks) and a good eye for UI detail, including spacing, consistency, accessibility and responsive behaviour.

Rails-literate: You're familiar with Ruby on Rails, including views and partials for rendering data, and you're comfortable debugging UI issues using browser dev tools.

CSS/design oriented: Write clean, maintainable CSS to implement responsive, accessible UI designs, using utility-first frameworks (e.g. Tailwind CSS) and modern layout techniques (Flexbox, Grid) within the established webpage design approach and keen to contribute further improvements.

Tested and collaborative: You've done some unit testing of JavaScript (Jest, React Testing Library or similar) and are familiar with Git and collaborative workflows, including branches, pull requests and code review.

Ready to grow: You're confident working independently on small-to-medium tasks as you get up to speed with the codebases and willing to ask for help; we'll teach you the specific tools, libraries and frameworks used for our specific stack.
