Founding product engineer

About Serova

Serova builds personalized cancer vaccines. Each vaccine is made for the individual patient from their own samples and given in partnership with their treating physician. We're a small team, and software runs everything we do, from the models that design each vaccine to the tools our scientists and patients use.

The role

We're hiring a founding product engineer. With tools like Claude Code, anyone can write code now, so what matters most is judgment: knowing what to build and what it should feel like.

You'll own product from idea to production across design, frontend, backend and infrastructure, working closely with the team to build the tools that power our program.

Who you are

• A smart generalist with taste

• You ship fast and work well without a spec, a designer or a PM

• High agency, friendly and low ego

• Curious about biology. No science background needed.

Requirements

• 2+ years of full-time engineering experience

• Real startup experience, Seed to Series B, in small teams without heavy process

• Fullstack: you've owned both frontend and backend

• Based in the San Francisco Bay Area or London, or willing to relocate

• Authorized to work in the US or UK, or a realistic path to get there

What will make you stand out

• UI/UX design experience. The ideal person is close to a design engineer.

• Evidence of taste, such as a personal site, portfolio or a great side project

• You've shipped a consumer-facing or design-led product that people other than engineers used

• You've been a founder or one of the first 10 employees somewhere, including your own venture-funded company even if it didn't work out

• Range: design, frontend, backend and infra all in the same job

• You've built scientific or data-heavy interfaces such as dashboards, visualizations or tooling over complex data

• Experience with our stack: React, TypeScript and Python. Strong generalists from a similar stack are welcome too.

Details

• Location: Hybrid in San Francisco, or in person in London

• Type: Full-time
