We're looking for a Lead Front-End Engineer who thrives in fast-moving startup environments and can take full ownership of features from design to deployment. You'll work closely with product to build performant, accessible experiences on our React/TypeScript stack — and you actively use AI tools (Copilot, Claude, Cursor) to ship faster and with higher quality.

We intentionally remain a small, fast, demanding team of senior engineers, with a high bar for execution and quality.

What you’ll do:

• Own and deliver front-end features end to end, from technical design through implementation, testing, and production monitoring, with minimal oversight.
• Architect scalable, maintainable front-end systems using React and TypeScript, making pragmatic trade-offs between speed and long-term code health.
• Leverage AI-assisted development tools daily to accelerate code generation, reviews, debugging, and testing, and drive their adoption across the team.
• Collaborate tightly with Product, and Backend engineers to shape features from the earliest stages.
• Mentor junior and mid-level engineers through code reviews, pair programming, and architectural guidance.
• Manage and coordinate with off-shore engineers to parallelize work and ship faster.

What you bring:

Must Have: 6+ years building production web apps and deep knowledge of modern React patterns. Experience in a startup or scale-up environment with a strong ownership mindset.

Nice to Have: Exposure to backend technologies (Node.js, REST/GraphQL, Python). Interest in building AI-powered tools or integrating LLMs into product features. Daily use of AI coding assistants as a core part of your workflow.

What we offer

• • Hybrid work setup with minimum 3 days/week in our Paris office.
  • High ownership and autonomy
  • Diverse, international team across Europe
  • Exposure to cutting-edge AI, voice, and enterprise deployments
  • Fast-paced environment with strong learning curve

  • Private healthcare (based on country- but for France it's 50% coverage for you, and 100% Coverage for your kids
  • Swile (France only)
