What You’ll Do

At Fresha, we believe AI is a force multiplier for feature delivery, not just a coding assistant. We provide every engineer with top-tier tooling (Claude, GitHub Copilot, Cursor) to strip away technical toil—so you can focus your energy on shipping high-impact product features. We value engineers who know how to leverage these tools to drive momentum within our 6-week cycles, accelerating the journey from concept to code while maintaining the deep technical judgment to verify, secure, and own the final user experience.

• Design, build, and ship new user-facing features in React + TypeScript, reaching millions of professionals and clients.
• Own features end-to-end: discovery, technical design, implementation, testing, rollout, and observability.
• Tap into (and extend) our Design System to ship polished UI quickly while raising the bar for consistency.
• Write robust automated tests (Cypress, Jest, React Testing Library) and keep the CI/CD pipeline green.
• Partner closely with Product, Design, Backend, Infrastructure, and Mobile engineers to take features from discovery to rollout and beyond.
• Accelerate with AI: harness AI agents, LLM-powered coding tools, and access to a wide range of AI tools (e.g., chatbots, dev assistants).
• Curious about backend, DevOps, or mobile? Great - we’ll support you in exploring any part of the stack.

What We’re Looking For

• AI-Augmented Workflow: You have deep experience building and interacting with AI agents, using them to amplify your output to 5x that of manual coding. You are able to integrate agents into our workflow while strictly adhering to our architecture and security standards, taking full accountability for ensuring all generated code meets the quality expectations of a Senior Engineer.
• Deep expertise in modern React & TypeScript, with a track record of shipping large-scale, consumer-facing web apps.
• Solid grasp of GraphQL (Apollo or urql) and REST fundamentals.
• Experience working with design systems.
• Fluency in web performance, cross-browser, and responsive design best practices.
• A testing mindset and familiarity with JS/TS testing frameworks.
