You’ll work in a cross‑functional agile team and contribute across the full development lifecycle, while growing your skills through pairing, code reviews, and mentorship. This is a great fit if you enjoy working across the stack – React/Next.js & TypeScript on the front end and Java/Spring Boot on the back end.
Key Responsibilities
* Deliver features across the stack: build UI with React/Next.js + TypeScript and services/APIs with Java/Spring Boot.
* Collaborate closely: pair programming, code reviews, refactoring, and writing tests (unit, component, end‑to‑end).
* Quality & accessibility: follow clean code, secure coding practices, WCAG‑aligned accessibility, and front‑end testing strategies.
* Help maintain clear, up‑to‑date technical documentation to make onboarding easier for new team members.
* Agile ways of working: actively engage in stand‑ups, planning, reviews, and retrospectives.
Knowledge, Skills and Experience
Required qualifications
* Some commercial experience (or substantial project/placement work) building web applications.
* Front end: basics with React and TypeScript; familiarity with Next.js (routing, data fetching).
* Back end: fundamentals in Java and Spring Boot (building simple REST endpoints, data access).
* Testing mindset: exposure to Jest/React Testing Library and JUnit on the server side.
* Version control: comfortable with Git, branches, pull requests, and code reviews.
* Databases: basic SQL and awareness of document/relational databases.
* Communication: clear written and spoken English; collaborative and open to feedback.
* Education: Bachelor’s or Master’s in Computer Science/related field or equivalent practical experience (e.g., bootcamp, strong portfolio, internships).
Other qualifications
* Azure familiarity and CI/CD with Azure Pipelines or GitHub Actions.
* Containers & cloud basics: Docker, environment configuration, and deployment fundamentals.
* OpenAPI/Swagger (design/consumption) and API tools (e.g., Postman, Bruno).
What do we offer?
* A dynamic, international and challenging work environment.
* Training and support to reach your full potential including the opportunity for continuous professional development.
* Attractive terms and conditions, including competitive salary, pension package and a range of flexible benefits and rewards.
