Senior & Staff Product Engineers - Tech agnostic, TS, Python, Rust, Go | YC-Backed HealthTech AI start-up, Seed stage | Salary £100-150K base + Equity | London, Hybrid

I’m working with a YC-backed HealthTech company building technology to tackle some of the biggest challenges facing modern healthcare at scale.

Their platform is making healthcare simpler to navigate - helping people find the right care, while giving healthcare organisations better technology to manage demand at scale.

They’re now looking for Senior & Staff Product Engineers to join their high-calibre engineering team in London.

They’re completely language agnostic - whether your background is Python, Go, Rust, TypeScript, Java/Kotlin or similar, they care far more about exceptional engineering, product thinking and ownership than expertise in one particular stack.

What you’ll be doing

• Own complex product problems end-to-end, from discovery through to production.
• Build and scale products used in real-world healthcare environments.
• Design reliable APIs, backend services and distributed systems.
• Work closely with Product and Design, rather than simply working from predefined tickets.
• Make pragmatic architectural and technology decisions.
• Integrate AI/LLMs where they genuinely improve the product.
• Improve scalability, performance, reliability and developer experience.
• Help shape engineering standards and technical direction as the company scales.
• At Staff level, influence engineering beyond your immediate team and raise the technical bar across the organisation.

They’re deliberately technology agnostic and care much more about engineering ability, product thinking and ownership.

• 5+ years of strong software engineering experience, operating at Senior, Lead, Principal or Staff level.
• Deep expertise in at least one modern language - Python, Go, Rust, TypeScript, Java/Kotlin etc.
• Strong backend and systems fundamentals, with the willingness to work across the stack when the product requires it.
• Experience building and operating high-quality production software at scale.
• A genuine product engineering mindset - thinking about users, outcomes and trade-offs rather than simply completing tickets.
• Experience in a start-up, scale-up or similarly high-ownership environment.
• High standards around code quality, testing, observability, reliability and simplicity.
• The ability to take an ambiguous problem and independently turn it into a great product.

Experience in HealthTech, FinTech, infrastructure or other complex/high-stakes environments is useful, but absolutely not essential.

The opportunity | Senior & Staff Product Engineers - Tech agnostic, TS, Python, Rust, Go | YC-Backed HealthTech start-up, Seed stage | Salary £100-150K base + Equity | London, Hybrid

• £150,000+ base salary + meaningful equity
• Senior & Staff opportunities - tonnes of ownership
• YC-backed, high-growth HealthTech
• London - 4 days per week in the office

This should appeal to engineers who want to remain hands-on, solve genuinely difficult technical and product problems, and have significant influence over both the technology and the product being built.
