Senior​/Software Engineer

We're unlocking access to the NHS, because healthcare is not truly free until it's truly accessible

The world’s best healthcare, for free. It's not a new idea, it's called the NHS. But the largest healthcare provider is fundamentally broken. Patient satisfaction is at an all time low, and the biggest reason cited is lack of access. So we’re on a mission to fix it with technology that actually works.

We're building the front door of UK healthcare, creating a future where one billion NHS appointments are transparent and instantly bookable, and patients are guided to the right service first time using AI.

We're developing critical national infrastructure. Today, 26% of GP practices in England use our patient registration software, while one in five GP practices in London use Bookable Search to help new patients find and book appointments seamlessly.

Our latest product, Bookable Navigator, extends this vision by automatically booking appointments for existing patients.

We operate from within a working GP practice in East London. We're backed by Y Combinator, Innovate UK and the NHS Clinical Entrepreneur Programme, and were previously ranked the 8th fastest-growing startup in the UK and 33rd fastest-growing in Europe

Exciting challenges lie ahead. Guided by our principles, we’ll meet these challenges with a thoughtful and caring approach. These principles drive everything we do at Healthtech-1:

This is for a product-minded full stack senior or staff software 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 7+ years of experience
• You're comfortable owning ambiguous problems end-to-end. You may have a founders/entrepreneurial mindset or have been a technical founder yourself.
• 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 care deeply about user experience, performance, and simplicity - you seek the feedback loop!
• You constantly raise the bar for both engineering and product.
• You pride yourself on producing high quality code which scales effectively into different environments.
• You understand and mitigate the risks of distributed systems, ensuring code that is failsafe even in the cases where things go wrong.
• Someone that thrives in autonomy, responsibility, and building things that truly matter.

• Fullstack (Backend leaning):
  Type Script or similar
• APIs:
  Designing and consuming scalable, well-structured services
• Data:
  Working with production systems and performance considerations
• AI:
  Integrating modern AI models into real-world healthcare workflows
• Experience in scaling product environments or high-stakes domains (health, finance, infra) is a strong advantage.

• 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!
