About Field Doctor

Field Doctor creates award-winning, chef-made and dietitian-designed meals tailored to specific health needs, including Type 2 Diabetes, Cancer, IBS and general wellbeing.

Since launching nationally in 2021, we've:

• Delivered over 1 million meals
• Reached £5m+ ARR with strong institutional backing
• Supported thousands of customers on their health journeys
• Built a modern, headless D2C digital product

We operate a subscription-first model with strong customer loyalty and a mission that genuinely improves lives. We favour pragmatic technology choices, off-the-shelf platforms, and increasingly leverage AI and low/no-code to move faster.

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
