About the Role
This is a hands-on, frontend-first senior engineering role, reporting directly to the Director of Technology. This is a high-autonomy role in a small team, suited to engineers who are comfortable managing their own priorities and momentum.
You’ll play a key role in scaling our Shopify Hydrogen headless storefront, improving performance, shipping features quickly, and supporting the launch of our mobile app. It’s an excellent opportunity for a strong engineer stepping into their first senior role, with real ownership and autonomy.
You’ll work closely with design, operations and growth to build a faster, more reliable, and more scalable customer experience.
What You’ll Do
* Build and ship customer-facing features using React, TypeScript and Shopify Hydrogen
* Implement high-quality, accessible, responsive UI from design
* Maintain and evolve our component library and design system
* Support mobile parity within our WebView app (launching 2026)
* Leverage low-code / no-code tools where appropriate
* Embrace modern LLM and AI tooling as part of day-to-day delivery
* Improve code quality, structure, documentation and testing
* Support experimentation, analytics, A/B testing and performance optimisation
* Diagnose and resolve issues across browsers, devices and edge cases
About You
* Strong experience with React and modern TypeScript/JavaScript
* Able to deliver polished, production-ready UI
* Comfortable improving performance and debugging complex issues
* Pragmatic, curious, and ready to take on more ownership
* Good design instinct and attention to detail
* Clear communicator and collaborative team member
* Comfortable working with analytics and experimentation
You’ll Thrive Here If…
* You’re the kind of engineer who sees an ambiguous problem and feels energised, not blocked, by the need to define the solution yourself
* You’re comfortable working in a fast-paced startup environment
* You like taking end-to-end ownership of problems, not just writing code handed to you
* You’re pragmatic and outcome-focused, favouring progress over perfection
* You’re curious about using AI, low-code, and modern tooling to move faster
* You care about building products that have real-world impact on people’s health
What We Offer
* Circa £60,000 salary
* Company options scheme
* Remote-first working within the UK
* Direct collaboration with senior leadership
* A small, mission-driven team
* Discounts on our meals
* The chance to shape a health-focused digital product with real impact
