Looking for your next challenge as a Frontend Engineer? We may have the right opportunity for you.

At B3, we start with people and their experience. We match projects to your skills and professional growth path. Our consultants work across a wide range of industries and technologies, delivering IT projects both in Poland and internationally. This allows you to build your career in a deliberate way - not by chance.

We are part of an international organization listed on Nasdaq Stockholm, operating in 11 countries. In Poland, we operate with full autonomy. We choose our technologies, processes, and ways of working while maintaining the highest professional standards.

Join us today.

  • Work in a Scandinavian culture built on logic, trust, and open dialogue.

  • Health and sports benefits tailored to your needs.

  • Speed Coaching – short sessions designed to provide new perspectives and solutions.

  • Sports training, an internal team, and opportunities to take part in competitions.

 

Obszary stanowiska:

  • Frontend development in React & TypeScript - Designing and implementing advanced UI components within a large-scale R&D product, with a focus on architecture, scalability, and performance optimization

  • Application state management & business logic - Building complex application logic beyond UI assembly, including Redux state architecture, asynchronous operations, API integration, and data flow design

  • Code quality & engineering standards - Writing unit and integration tests, applying SOLID principles, participating in Code Reviews, and contributing to architectural decisions in an agile R&D environment

 

Czego potrzebujesz, żeby do nas dołączyć:

Must have:

  • Advanced knowledge of React - functional components, Hooks, Context API, lifecycle, performance optimization and component reusability

  • Proficiency in TypeScript - types, interfaces, generics, typing of React components, hooks, Redux actions and API data

  • Strong Redux knowledge - architecture principles, react-redux integration, state immutability, selectors and performance optimization

  • Practical knowledge of Atomic Design and experience implementing complex business logic (asynchronous operations, API integration, error handling, MVC pattern)

  • Experience with unit and integration testing, Git-based version control and Code Reviews; familiarity with SOLID principles and design patterns

  • English B2+

  • Eligibility to work on territory of Poland (citizenship, visa, work permit, etc.)

Nice to have:

  • Experience working in R&D environments, designing non-standard solutions

  • Architectural mindset - ability to advise on architectural decisions, predict consequences of technical choices (scaling, performance, extensibility)

  • Knowledge of end-to-end testing for key use cases
