Are you a frontend software developer with experience in React or Angular? If yes, this could be your ideal next role!
A well-funded, research-led technology start-up is seeking a Mid–Senior Front-End Developer to join its growing team in Cambridge.
This is a high-impact role where you’ll take ownership of front-end development, working closely with engineers and researchers to translate complex systems into intuitive, production-ready user experiences.
The Role
As a Front-End Developer, you will lead the design and development of modern web applications - taking products from early-stage prototypes through to full production deployment.
You’ll work in a highly technical, fast-paced environment, collaborating with backend engineers and research teams to build interfaces for sophisticated AI-driven systems.
While this role will evolve into leading a small front-end function, it remains hands-on and development-focused.
What You’ll Be Doing:
* Designing, building, and maintaining modern front-end applications using React or Angular.
* Taking ownership of projects from prototype through to production deployment.
* Translating complex technical workflows into clean, user-friendly interfaces.
* Ensuring performance, scalability, and maintainability of front-end systems.
* Contributing to architectural decisions across the wider platform.
* Mentoring and supporting other front-end developers as the team grows.
Essential Skills & Experience:
* 5+ years’ commercial experience in front-end development.
* Strong experience with React or Angular (experience with both is advantageous).
* Proven ability to own and deliver front-end projects end-to-end.
* Solid understanding of modern front-end architecture, state management, and tooling.
* Experience working with APIs and backend-integrated systems.
* Ability to read and understand Python-based codebases (particularly research prototypes).
* Strong problem-solving skills and ability to work independently.
* Excellent communication skills when working across technical disciplines.
Desirable Experience (Not Required):
* Experience working on LLM-powered or AI-driven applications.
* Exposure to agentic workflows or complex computational systems.
* Background in start-ups or early-stage environments.
* Experience building developer tools, dashboards, or technical UIs.
Who You Are:
* Comfortable operating in a fast-moving, research-heavy environment.
* Curious and motivated by technically challenging problems.
* Able to bridge the gap between complex backend systems and user experience.
* Proactive, adaptable, and ownership-driven.
* Interested in working closely with highly technical engineers and researchers.
