• Join a high-growth environment backed by elite investors like Creandum, 20VC, and YC, with company revenue quadrupling in the last year alone.
• Work with a world-class engineering team from Babylon, SpaceX, and Monzo on the mission-critical challenge of making healthcare proactive and affordable.

What You Will Do

• Build and own end-to-end full-stack features for customer-facing dashboards that allow healthcare providers to self-serve and order lab tests.

• Collaborate directly with customers to understand product usage, refining technical challenges into elegant software solutions that significantly reduce patient medical costs.

The ideal candidate

• Has 3+ years of experience in early-stage startup environments where you actively influenced product direction rather than just executing predefined tickets.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
