Machine Learning Engineer at Terranox AI

We are looking for the first dedicated Machine Learning Engineer to join a high-growth startup backed by General Catalyst and Y Combinator. This San Francisco-based team is revolutionizing the energy sector by using AI to solve the global uranium shortage, a critical bottleneck for clean nuclear power. You will build computer vision models from scratch and lead the ML strategy for a company addressing the world’s most pressing energy challenges. If you have 5+ years of experience and want to ship models that have a tangible impact on the physical world, this is your chance to lead from zero to one.

About this role

Role overview

As the first dedicated ML hire, you will build the core systems that drive nuclear fuel discovery. You'll train custom computer vision models on complex, sparse geological data and deploy them into production. This is a high-impact role solving novel problems without an off-the-shelf playbook to address the global energy crisis.

Terranox AI

YC and General Catalyst-backed startup using AI for uranium discovery to power the clean energy transition

What you'll do

What you will do

  • Design and train computer vision models from scratch using messy, sparsely-labeled geospatial and geological data sets.
  • Build and maintain the end-to-end ML production pipeline that translates model outputs into real-world discovery decisions.
  • Synthesize recent ML research into practical, shipped systems that address ambiguous problems in the nuclear energy sector.

Who you are

Who this is a fit for

  • Has 5+ years of professional ML experience with a proven track record of taking complex systems from concept to production.
  • Possesses deep expertise in computer vision and the ability to work comfortably with non-standard or sparse-label regimes.
  • Thrives in early-stage environments, demonstrating the ability to frame and solve ambiguous problems independently in a fast-paced San Francisco office.

Why this role

Why this role is remarkable

  • Join as the first dedicated ML engineer at an early-stage company backed by premier investors including General Catalyst, 776 Ventures, and Y Combinator.
  • Tackle a unique, high-stakes problem: using AI to solve the structural uranium shortage and enable scalable, clean baseload energy for the planet.
  • Lead the development of a build-from-zero ML stack where you have full ownership over model architecture and production pipelines for multi-modal data.
