Senior Fullstack Engineer, Freelance

bsport

• Take ownership of major frontend initiatives, help lead complex technical projects, and work directly with leadership to define the future of our platform. • Help us address technical debt, a complete revamp of our client interfaces, build and maintain our in-house design systems, and build scalable solutions for one of our product verticals. • Roughly 70% of your time — front-end / back-office revamp: Own the revamp of key back-office pages and features within the Booking scope (list and detail views, member profiles, establishment pages, teacher tools…) • Implement interfaces from high-fidelity prototypes delivered by our dedicated designer • Write clean, tested React (TypeScript) code aligned with our internal design system • Collaborate with internal engineers to ensure long-term maintainability • Roughly 30% of your time — backend support for the revamp: Evolve and adapt the backend logic that powers the revamped front-end features (APIs, data models, business rules) • Ensure the back-office pages you're rebuilding are fully supported end-to-end — not just visually, but functionally • Work closely with internal backend engineers to align on contracts, flag dependencies early, and unblock front-end delivery

Job Requirements

  • 5+ years of full-stack experience, with genuine front-end depth in React (TypeScript)
  • Solid backend skills in Python (Django or FastAPI), comfortable with high-volume systems
  • At ease in a hybrid role — able to deliver polished UI and review a backend PR in the same day
  • Informal technical leadership: you share feedback in code reviews, document decisions, and help others grow
  • Strong written communication skills in English
  • Background in a startup or scale-up, ideally B2B SaaS

Benefits

  • A varied mission with direct product impact in the short and medium term
  • A modern stack
  • A high-growth context with an engaged team and strong engineering standards
