Machine Learning Researcher

Join to apply for the Machine Learning Researcher role at Orbital

Orbital’s hardware solutions solve the biggest challenges in data centers. Each of our products contains an advanced material discovered with our AI, giving it breakthrough real-world performance. We’re looking for ambitious thinkers and builders; those excited by the challenge of bridging AI and industry, chemistry and computation, discovery and deployment.

Our mission is to usher in an era where new, advanced materials are both discovered and engineered with AI and we will use this to build hardware that solves major global technology challenges.

Joining Orbital Materials means working at the intersection of deep tech, applied science, and engineering innovation. We are a truly global organization with teams in London, UK, San Francisco (CA) & Princeton (NJ), building teams in ML Research and Product Development to Mechanical and Chemical Engineering, offering opportunities for talented individuals who want to shape the future of materials and their applications in high-impact industries.

As a Machine Learning Researcher at Orbital, you'll work on world-class foundation models for atomistic systems, pushing the boundaries of AI-driven materials discovery. You'll design and implement cutting-edge ML architectures whilst collaborating closely with experimental scientists to translate foundational research into breakthrough real-world applications. This role offers the opportunity to pursue ambitious, high-quality research that directly accelerates our mission to solve major global technology challenges through AI-discovered advanced materials and beyond.
