• Drive massive impact by putting frontier AI into the hands of Fortune 500 firms, replacing slow, expensive traditional research with instant, accurate simulations.
  
  

What You Will Do

• Own the complete lifecycle of product features, from initial scoping and database modeling in Postgres to shipping polished TypeScript frontend interactions.
• Partner with research engineers to integrate the latest simulation engine capabilities into the user-facing product, ensuring speed, reliability, and high-stakes accuracy.
• Collaborate on product vision and design, pushing back with technical insights to ensure every feature feels intuitive and performs flawlessly at scale.
  
  

The ideal candidate

• Has at least 2+ years of experience as a software or product engineer, with a proven track record of shipping end-to-end features to users.

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.
