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

- 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.
