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 🚀

💙 Care deeply
🏋️♀️ Work hard

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
💙 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 Accelerator, backed by the NHS Clinical Entrepreneur Program, winners of the London Business School Healthtech Challenge, Innovate UK, and Y Combinator (S23).
💉 Paid volunteer days. We offer an additional 2 paid days off per year where you can give back to your mission of choice.
🎢 Every 8 weeks we take a day off to socialise as a team. In the past we’ve hiked box hill, raved at All Points East and spent one rainy day at Thorpe park. This works out as 6 working days a year.
📚 Learning budget of £250 annually and time off to spend it - we care about this; this is flexible and based on need but everyone will receive a yearly allocation towards their continual growth.
🍽️ Homemade breakfast and lunch are on the house when you're in the office, ensuring you're fuelled for success!
🥡 Team takeaways every Monday night
🥗 Health and fitness budget of £60 per month - see more here
🧘♂️ An additional 7 days of paid leave is available if you want to take time to learn how to meditate.
💫 Tooling; You’ll have your choice of operating systems and any additional tools you need to do your best work (e.g. keyboard, additional monitors, mouse etc). If you’re on our Engineering teams you’ll receive the latest MacBook Pro and our Growth & Ops teams receives a MacBook Air.
🩺 We know health and family come first which is why we have a generous sick leave policy with additional days that can be taken for mental health leave.
✈️ We prioritise time outside of work to bond, once a year we’ll holiday together! Destination chosen by popular vote. In 2025, we spent 8 days in a surf camp in France!
👎 No private medical insurance, because we believe in the NHS and we are here to improve it!
🐥 Parental leave: Post passing probation it is: statutory - 6 weeks 90% pay then, SMP for 33 weeks; if you've been an employee for a year: 12 weeks 100% pay then, SMP for 27 weeks; and if you have been here for 2 years: 18 weeks 100% pay then, SMP for 21 weeks. This will improve over time. We also include up to £9,000 of childcare contribution for primary caregivers to support a five-day return where possible.
👪 Fertility leave. We understand how difficult a fertility journey can be. This is why we give an extra 5 days off per year if you or your partner are going through fertility treatment.
🐖 Pension - We operate a standard 3% employer contribution and employees auto-contribute 5% of their salary. We use Nest as our provider.
🏡 Local living benefit - A one-off benefit to support living closer to the office: £5,000 if you live within a 30-minute walk, or £2,500 within a 30-minute bike. It is optional, available immediately on signing, and not linked to performance or progression.
🚕 If you choose to work late in the office, you can expense dinner after 7pm and an Uber home after 9pm, or earlier if you feel unsafe travelling in the dark. This is optional and about wellbeing, not performance or expectations.
⛵️And of course, an adventure of a lifetime!
We care about building a product that is loved and a culture that is rich in perspectives, experiences, and backgrounds.
Our team represents more than ten different cultures. We come together every lunch time for a home cooked meal, rotated among team members!
We want everyone in our team to know that they belong. We are purposeful about this and are proactively building a company that is inclusive of all people; from race, religion, sex, sexual orientation, gender identity, age, neurodiversity, disability, colour, and national origin - essentially every type of diversity. We don’t just want people who fit in, we want them to fit together. We're active in continually improving the way we make this happen.
