Job title: Founding Applied Scientist
Job location: San Francisco, CA, US
Job listing URL: https://www.ycombinator.com/companies/terranox-ai/jobs/9xGzcvz-founding-applied-scientist
Job description: **About Terranox** We're the first AI-powered uranium discovery company. Nuclear is the only clean, scalable, and baseload energy source available today, and we’re structurally short on uranium. We're addressing that by applying AI/ML to a discovery process that hasn't fundamentally changed in decades. Backed by General Catalyst, 776 Ventures, Y Combinator, and others. **The role** You'll be our founding applied scientist, anchoring the scientific foundations of our discovery stack. You'll lead how we work with the full range of geoscientific data — geophysical, geochemical, geological, and remote sensing — from what we acquire, to how we process and integrate it, to how it feeds the systems that drive our targeting decisions. Much of the work has no off-the-shelf playbook. **Requirements** * PhD in geophysics, applied physics, computational physics, applied mathematics, or a closely related field; or equivalent deep technical expertise * Deep experience with exploration geophysics and with geophysical inversions * Strong scientific computing skills (Python, the standard stack) * Working fluency with ML — you can be a real thought partner on what we're building * Comfort with ambiguous, sparse, multi-modal data **Bonus** * Experience working alongside ML researchers or engineers * Prior early-stage startup experience **Logistics** * In-person in San Francisco
