We’re looking for a founding full-stack engineer to help us accelerate the pace of scientific discovery.

Our stack is primarily React, Next.js and Javascript/Typescript. And we’re updating parts of the back-end to Python. You should have familiarity with building + improving a high-quality well-designed web app in production.

In this role, you’ll:

  • Improve Unriddle by shipping product features, fixing bugs and removing technical debt.

  • Move fast but polish things -- we deeply care about good design but we don’t let this slow us down.

  • Develop strong opinions, be able to communicate them and turn them into features.

  • Build internal tools to automate non-product work. We do this a lot.

As a founding member of the team, you'll make a significant impact as we rapidly scale revenue from $1M to $10M and then $10M to $100M+.

You’re likely a good fit if you:

  • Have independently built and scaled a product to at least a few thousand users (e.g. a side project or open-source project).

  • Have worked in a high-growth, fast-paced environment (ideally another startup) and can drive things forward with relatively little oversight.


  • Familiarity with AI and ML concepts, especially in the context of natural language processing and generative AI models.

  • You’ve previously built a consumer product, or worked at a top consumer company before.

If interested, reach out with a couple of sentences about you, links to what you've shipped before and what you want to do for us starting next week.
