Job Description

Paris (Hybrid) | Full-time | Base Salary + Equity

A fast-growing startup. Real ownership. Equity that actually matters.

At bsport, we’re building the operating system for the wellness industry — and we’re at a pivotal moment. Fresh off a €30M Series B, our engineering team is scaling fast, our product is evolving deeply, and we’re raising the bar for technical excellence across the platform.

We’re looking for a Senior Frontend Engineer who wants more than just shipping tickets. This is a role for someone who wants ownership, technical influence, and a clear path toward staff or leadership roles as the company grows.

Why this role in different?
You’ll join at the right time strong product-market fit, ambitious growth plans, and space to shape architecture and standards.

• You’ll work on deep, long-term frontend initiatives, not surface-level UI work.

• Your decisions will matter — you’ll collaborate closely with Tech Leads, Engineering Managers, and Product leadership

• Equity is meaningful: our goal is to triple valuation within 2 years.

You’ll take ownership of major frontend areas and help define how our platform evolves.

• Lead complex frontend initiatives end-to-end

• Drive a full revamp of client-facing interfaces

• Build and evolve our in-house design systems

• Tackle technical debt with scalability in mind

• Design reliable, scalable frontend solutions for one of our core product verticals

• Contribute to long-term architectural decisions as we scale teams across locations (including our core teams in Paris)

Our frontend stack:

• ReactJS + TypeScript. Micro-frontends, orchestrated with NX

• Zustand for state management

• Custom in-house design systems

Strong experience in React is great - but if you come from another major frontend framework and are excited to learn, you’ll fit right in.

Requirements:

• 5+ years of frontend experience in SaaS or product-driven companies

• You take ownership, show initiative, and enjoy solving hard problems

• Comfortable working on large, evolving codebases

• Strong communicator, fluent in English

• Curious, pragmatic, and motivated to grow with the company

We are offering: €60,000 – €90,000 base salary + equity Salary level will depend on your technical evaluation during interview process. We have 3 core technical interviews: Live Coding, Tech Talk, System Design.

You will have a Hybrid setup (Paris office) with 2 remote days per week.

Additionally:

• 15 days per year working from abroad

• Full health insurance with Alan

• Real growth opportunities as the engineering team doubles this year
