Job description

Let’s make the NHS the most advanced healthcare system in the world.

The world’s best healthcare, free. It’s called the NHS, but the largest provider is fundamentally broken. We’re on a mission to fix it with technology that actually works. The NHS is accessible to all, but it’s under intense pressure with rising costs, GP strikes, budget uncertainty and an ageing population, leading to longer waits and lower quality care. Staff spend 35% of their time on mundane admin – that’s where we make a difference by relentlessly automating repetitive processes. Our first product, Automated Registrations, is already used by 24% of GP practices in England. We’re building more powerful tech to unlock access to healthcare for the entire nation.

Our Principles

• Care deeply
• Work hard
• Be your word
• Trust in radical truth and transparency
• Do your life’s best work
• Find the fun

The mission

We have an ambitious mission: to unlock access to healthcare by getting patients to the right appointment the first time. We are hiring a Senior Product Engineer to build secure, reliable systems for patients and clinicians and to integrate the latest AI models into the patient care navigation experience.

Goal expectations

The North Star for the company is 50,000 weekly appointments booked by September 2026. Your high‑level goals will remain the same and will include:

• Build something great that patients and practices want; work closely with product and users to deliver the right solution.
• Oil the technical engine; pay down debt, identify scaling problems and propose strategic improvements.
• Ship at pace with high‑quality code and efficient reviews.

Scope of the role

You fully own

• The quality and speed with which you deliver tickets.
• The quality of your code reviews.

You co‑own (with Product and Engineering)

• Technical roadmap and investment items.
• Reliability of the system.
• The design of solutions.

You influence (but do not own)

• The product roadmap.
• Tooling and software that the company pays for to improve developer productivity.

Must‑have traits

• High ownership: personally responsible for production systems, including incidents and long‑term maintainability.
• Strong engineering fundamentals: deep understanding of data modelling, API design, concurrency and failure modes.
• Product judgment: balance speed vs quality and make trade‑offs without waiting for permission.
• Strive for simplicity: choose well‑understood solutions over clever ones unless a clear reason exists.
• Comfort with ambiguity: turn vague problems into shipped, reliable solutions.
• Product care: deeply care about building delightful product experiences and speaking to practice staff.

Desired traits

• Strong TypeScript proficiency in large, long‑lived codebases.
• Design and maintain APIs used by multiple internal or external consumers.
• Production experience with relational databases (Postgres preferred); monitoring, alerting and incident response.
• Familiarity with NestJS or similar backend frameworks (Express, Fastify).
• Experience with data pipelines, analytics or ML/AI system integration.
• Experience working in regulated or high‑stakes domains (health, finance, infrastructure).

Required Experience

• 3+ years as a software engineer.
• At least 1 year at a startup or scale‑up.

Benefits

• Paid volunteer days: 2 paid days off per year.
• Learning budget of £250 annually.
• Health and fitness budget of £60 per month.
• Additional unpaid leave or paid leave for mental health and fertility.
• Pension: standard 3% employer contribution with employee auto‑contribute 5% of salary.
• Local living benefit: £5,000 if you live within 30‑minute walk of office, or £2,500 within 30‑minute bike.
• Inclusive and diverse culture with support for diverse backgrounds, genders, abilities and more.

We care about building a product that is loved and a culture rich in perspectives, experiences and backgrounds. We actively improve inclusion and belonging for all team members.
