Senior Frontend Developer

Senior Frontend Engineer required for a well-funded AI healthcare startup building new-gen patient-facing software. This is a great opportunity to take ownership of frontend development across products combining AI with real clinical care.

As a Senior Frontend Engineer, you'll build and improve the interfaces used by patients and clinicians every day. You'll work with React, Next.js and TypeScript to deliver fast, polished applications while collaborating closely with backend and AI engineers to bring new features into production.

This Senior Frontend Engineer position offers genuine technical ownership, from frontend architecture and design systems through to performance, accessibility and user experience.

What we're looking for:

• 5+ years of front end engineering experience, ideally within a Series A–C startup.
• Healthcare or regulated industry experience would be a significant advantage.
• Expert-level TypeScript, JavaScript, React and Next.js.
• Strong CSS, animation and design system expertise.
• Experience shipping production B2C or B2B applications used by external customers.
• Good backend understanding and the ability to work across the stack.
• Familiarity with AI/ML products and LLM-powered applications.
• Bachelor's degree in a relevant discipline.

You'll suit this Senior Frontend Engineer opportunity if you've built customer-facing products in a fast-moving startup and care as much about usability and design quality as you do about clean code.
