Job Description:

Help rebuild the NHS with technology that actually works

The NHS is one of the most ambitious ideas in modern society: world-class healthcare, free at the point of use. But today, it’s under pressure from rising demand, constrained resources, and systems that weren’t built for modern care.

We’re here to fix that.

At Healthtech-1, we’re building the technology to unlock access to healthcare getting patients to the right appointment the first time. This isn’t about marginal gains. It’s about rebuilding critical infrastructure for millions of people.

Why this role matters

35% of NHS staff time is spent on admin. That’s the opportunity. Our first product is already used by 26% of GP practices in England, and we’re now scaling a platform that transforms how patients and clinicians interact with healthcare.

As one of our Senior Product Engineers, you’ll own and shape the experiences used every day by patients and clinicians where performance, clarity, and reliability directly impact care.

What we’re looking for

This is for a product-minded full stack engineer who wants to move with extreme urgency and have complete autonomy. You’ll help build and scale our product, working across teams and directly with our customers.

What we’re looking for:

  • You are operating at a senior or lead level and have 5+ years of experience, with expertise in React and TypeScript
  • You’ve experienced a startup or scale up especially at an early stage. You’ve been part of a small squad of high performing engineers and you weren’t just “one of many”
  • You may have a founders/entrepreneurial mindset or have been a technical founder yourself and get the early stage growth journey
  • You pride yourself on producing high quality code which scales effectively into different environments
  • You feel accountable for the end-to-end solution and can build our product which can handle various NHS “oddities”
  • You understand and mitigate the risks of distributed systems, ensuring code that is failsafe even in the cases where things go wrong
  • You thrive with autonomy, responsibility, and building things that truly matter.

Tech environment

  • Fullstack (Backend leaning): React, TypeScript (core focus)
  • APIs: Designing and consuming scalable, well-structured services
  • Data: Working with production systems and performance considerations
  • Experience in scaling product environments or high-stakes domains (health, finance, infra) is a strong advantage.

What success looks like

  • You ship intuitive, high-quality user experiences that clinicians and patients rely on daily
  • You influence product direction, not just implementation
  • You identify and solve performance and usability challenges before they become problems
  • You become a trusted voice across engineering, product, and design
  • The team delivers faster and better because of you!
