The Opportunity

We are looking for a Junior Software Developer to join our expanding Engineering Team at our Reading head office.

This is an excellent opportunity for an early-career developer to gain hands‑on experience across a modern full-stack environment, working on real production systems used globally by major FMCG brands. You\’ll contribute to both our Node.js/Koa backend and our React/Redux front end, learning from senior engineers while shipping meaningful features from day one.

Key Responsibilities

Backend

• Work in our Node.js + Koa codebase using decorator-based routing, building clean async/await flows and helping shape request/response transformations.
• Maintain and debug PostgreSQL queries using Sequelize and raw SQL; assist in building parameterised queries and understanding how filters pass through middleware.
• Contribute to simple instrumentation and logging to surface timing, latency, and error details.
• Reuse existing shared utilities (sorting, retailer helpers, date formatting) to ensure consistency across services.

Frontend

• Learn the React 18 codebase, react-scripts build flow, and component libraries such as Ant Design and HeadlessUI.
• Work with Redux Toolkit, middleware (Saga, Thunk, redux-logger), and Axios request flows to support asynchronous UI logic.
• Implement data-heavy charts and views using d3, Highcharts, and react-window, following performance guidance.
• Contribute to consistent UI styling via Sass/styled-components and support our i18n setup (react-i18next, i18next-scanner).

Quality & Tooling

• Support testing using Testing Library, Cypress (including visual regression), and MSW mock handlers.
• Follow established coding standards, Git workflows, and CI checks.

About You

You are curious, motivated, and eager to grow as a developer. You enjoy solving problems, learning new patterns, and collaborating with others. You want to develop strong full-stack skills while contributing to software used by some of the world\’s biggest brands.

Requirements

• Familiarity with React or Node.js (university, bootcamp, or personal projects welcome).
• Interest in backend APIs, databases, or data-heavy visualisation.
• Strong attention to detail and willingness to learn from feedback.
• Proactive mindset and desire to grow into a fully capable engineer.
