Frontend Developer

Senior Front End Engineer | Remote-first (UK) | 4-Day Work Week

I'm working exclusively with a fast-growing, mission-driven UK tech start up backed by some of the most respected names in the industry. They're building genuinely impactful software that is already being used by frontline public service teams across the country, and I'm looking for a Senior Front End Engineer to join their small, high-performing engineering team.

This is a founding-level hire. You won't be joining a large team with layers of process around you. You'll be hands-on, writing clean, confident code every day and working directly with the CTO, design and product to shape the product as it scales.

What you’ll be doing:

• Building and shipping features across a modern React + TypeScript frontend
• Translating product and design requirements into clean, production-ready UI
• Owning features end-to-end, from implementation through to production
• Writing maintainable, well-structured, tested frontend code
• Working directly with engineering, product, and design in a highly collaborative environment
• Helping shape frontend decisions as the product evolves and scales

What we’re looking for:

• Strong commercial experience with React + TypeScript
• Confident, hands-on coder, you are actively writing production code in your current role
• Proven ability to build and ship UI features independently
• Experience in start-up, scale-up, or similarly fast-moving environments
• Strong communication skills, able to collaborate clearly with technical and non-technical stakeholders
• High attention to detail and genuine care for the quality of your work
• Strong bias toward simplicity, clarity, and shipping

Why this role:

• 4-day work week, full 5-day salary
• Remote-first with optional London office access
• Real ownership and influence over a product that is making a tangible difference
• Backed by world-class investors with serious growth runway ahead

Please note sponsorship is not available for this role. You must have the right to work in the UK.
