Senior/ Staff 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 🚀

What we’re looking for
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.

Tech environment:

• Fullstack (Backend leaning): TypeScript 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.

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!

What’s on Offer
Salary: £90-130,000k (DOE) + founding-level equity
Location: London (Stratford) - Onsite 4 days

💙 A bit about us
💙 We’re all NHS staff. We’re inside-outsiders. Trusted with one of the biggest datasets in the world.
🏥 Our office is within a GP practice. This is our unfair advantage. Got a question? Pop down the corridor. Want to learn how your work affects real patients? Pop downstairs to reception.
💪🏼 4 days in the office and 1 day WFH (for most roles). We highly prioritise in-person communication and prefer candidates who want to work 4+ days a week in the office. Our anchor days are Mon, Tues, Thurs and Fri. Homemade breakfast and lunch are on the house every day when you're in the office, ensuring you're fuelled for success!
🌀 We work in growth cycles. Every 8 weeks we do the same set of activities. 1 week outside of Business-as-Usual to research, strategise, plan our work. 7 weeks to knuckle down and deliver it.
🤝 We’re highly collaborative. One of the benefits of a high trust team is we often work autonomously, but as a team we’re very collaborative by nature. Two heads are often better than one, and we frequently lean on each other to solve problems together.
🤜🏽 We’re backed by industry leaders. We’re on the DigitalHealth.London Accelerator, backed by the NHS Clinical Entrepreneur Program, winners of the London Business School Healthtech Challenge, Innovate UK, and Y Combinator (S23).…
