Founding Product Engineer - Applied AI

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:

1. 💙 Care deeply

2. 🏋️‍♀️ Work hard

3. 🤝 Be your word

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.

We're reimagining how technology, data, and AI can empower every team across the business.

You'll help build the platforms, tooling, and guardrails that enable teams to move faster while maintaining the highest standards of quality, security, and reliability. Our goal is to make it possible for anyone in the company to safely bring ideas to life and see their impact in production.

Some of the challenges you'll tackle include:

• Designing modern engineering workflows that accelerate delivery, increase autonomy, and improve developer experience across the organisation.

• Building shared tools and platforms that make information accessible, discoverable, and actionable for every team.

• Connecting knowledge across departments, enabling insights from customer conversations, support interactions, product discussions, and operational meetings to be surfaced whenever and wherever they're needed.

• Creating a unified, queryable data ecosystem that breaks down silos and allows people to ask meaningful questions across the entire business.

• Leveraging AI and automation to uncover opportunities, identify trends, and surface insights before anyone even knows to ask the question.

• Developing systems that amplify the impact of individuals and teams by sharing best practices, highlighting successful approaches, and accelerating the adoption of new ideas across the company.

This is an opportunity to work on foundational technology that influences how the entire organisation collaborates, learns, and delivers value to customers

Our Tech Stack:

• Fullstack (Backend leaning): React, TypeScript (core focus)

• 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.

We’re based inside a GP practice, so you can walk downstairs and see the real-world impact of your work.

Why join our engineering team:

• Build technology that actually matters at national scale

• Solve complex, meaningful problems with real-world constraints

• Work in a high-performing, product-led team

• Have real ownership, real responsibility, and real impact

💙 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).

💉 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.
