Join us to write the next chapter of your career!

About the role:
Take ownership of major frontend initiatives, help lead complex technical projects, and work directly with leadership to define the future of our platform. You’ll 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.

Our focus for the coming years is building reliable and scalable systems, and setting a new standard for technical excellence.

What you'll work on

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

Tech stack

• Front-end: React (TypeScript), Zustand, styled-components, internal design system

• Back-end: Django, Postgresql, AWS, Kubernetes

• Language-agnostic mindset: we care more about strong engineering principles than specific tools. That being said, a ground level in Python / postgresql is expected

Practical details

• Duration: 6 months (Q2–Q4 2026), with possible extension

• Pace: Full time (5 days/week)

• Location: Remote setup possible, office in Paris 10e

Who we're looking for

• 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

What this mission offers

• 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
