What you'll own & the role
Paris
Lead Design System Engineer
This is a lead role where you will have the opportunity to drive bsport's design system architecture, strategy, and vision, and have influence across the entire product, working closely with Design partner and Product teams.
Why this role is different?
Your initial focus will be Kaizen, our B2B design system powering our new back-office for studio managers, staff and teachers — a revamp is underway and you'll be leading the evolution of this Design system whilst all the company is building this new backoffice.
As you find your footing, the scope can expand to two additional systems: our white-label meta design system for B2C web, and our React Native mobile system. How these three systems relate, diverge, and potentially converge over time? That's yours to shape.
Lead the evolution of Kaizen, our B2B design system — architecture, component quality, documentation and adoption.
Drive accessibility improvements across the board — keyboard navigation, ARIA compliance, mobile interactions.
Own governance and standards: reduce redundancy, enforce consistency, and make sure product teams are building with the system, not around it.
Progressively extend your ownership to Fabrique (B2C web, white-label) and Okaia (React Native mobile).
Define how our design systems become AI-ready — machine-readable structure, cursor rules, agent-friendly naming conventions.
Bring vision on animation and micro-interactions to elevate the feel of our products.
Collaborate closely with our Sr. Design System Product Designer, with no PM or EM in between — high autonomy, high impact.
You would be great fit if you have:
You have 4+ years of front-end experience, with at least 1 year as the primary owner or lead contributor of a mature design system.
You have a designer's eye — attention to detail, taste for quality, and the ability to push back on "good enough."
You're a systems thinker: you see redundancy, inconsistency, and debt across a codebase and know how to create order without slowing teams down.
You're fluent in React and TypeScript, and have solid knowledge of web components and advanced CSS (you know the difference between vh and dvh and why it matters).
You follow the design systems space closely and have opinions: who's leading, what's overrated, what's next.
You're excited about how LLMs and agents change the way we think about component architecture and developer tooling.
You have a portfolio or GitHub that shows design system work — real components, potential decisions and real trade-offs.
Bonus: experience with animation, transitions, and performance-optimized motion.
Bonus: React Native experience, or appetite to learn.
Diversity is one of our most valuable assets, and we are committed to fostering an inclusive environment where everyone can contribute their best work. We welcome applicants from all backgrounds, identities, and experiences to help us build a more inclusive, equitable team.
If you’re excited about this role but don’t meet every qualification, we encourage you to apply-curiosity, adaptability, and a willingness to learn are just as important to us as specific skills.
