    We’re looking for a Junior Frontend Developer to help build and improve applications for our US clients - from early-stage MVPs to established products in FinTech, SportsTech, MedTech, and other industries.

    TypeScript, React, and Node.js are our bread and butter. We value solid fundamentals, curiosity, and a willingness to learn how applications work beyond a particular framework.

    We’re building a team of engineers who can contribute across the application while developing deep expertise in frontend or backend engineering. In this role, frontend is your primary discipline, and you’ll broaden your contribution across the stack as your experience grows. You’ll build this foundation with support from experienced teammates.

    AI-assisted development is part of this role. You’ll learn to use coding assistants for exploration, implementation, and debugging, while building the skills to understand their suggestions, check the results, and recognise when to ask for help.
