Senior Machine Learning Engineer
About the role
ML Engineer — Physical AI | Bay Area
About the Company
We partnered with a start up that is building the intelligence layer for the physical world.
While most AI today understands what things look like, this team is building systems that understand what things are at a molecular level.
The company has developed proprietary sensing technology capable of capturing, paired with large-scale world models that encode the physics and chemistry of real-world materials.
The company is bridging the gap between artificial intelligence and the physical world — giving machines the ability to perceive, reason about, and interact with their environment at a depth that has never been possible before.
Backed by leading venture firms, the team is assembling a world-class group of researchers and engineers to work on problems that sit at the frontier of what AI can do.
What the Company Is Building
Large world models that understand the physics and chemistry of real-world materials — not just pixels
A proprietary sensing platform that reads the molecular fingerprint of physical matter across thousands of spectral bands
Perception systems that enable machines to understand what they're touching, seeing, and interacting with at a chemical level
AI infrastructure that maps the material composition of the physical world in unprecedented detail
Real-world applications spanning robotics, earth observation, industrial sensing, and beyond
What the Role Involves
Designing, training, and scaling foundation models for physical-world understanding — working across spectral, spatial, and temporal data modalities
Developing and iterating on model architectures, training pipelines, and evaluation frameworks tailored to physical sensing data
Building production-grade ML systems that operate on real-world data at scale — not just benchmarks
Collaborating directly with hardware and sensing teams to close the loop between perception and intelligence
Pushing the boundaries of what world models can represent — materials, chemistry, physics, and beyond
What the Team Is Looking For
Strong experience in ML research or research engineering, with a focus on training and scaling models (LLMs, vision models, world models, or multimodal systems)
A track record of shipping ML systems into production and not just publishing papers
Comfort working across the full stack: data pipelines, training, evaluation, and deployment
Intellectual curiosity and genuine excitement about applying AI to the physical world
Why This Opportunity
Frontier problem space: The role offers the chance to work on AI systems that perceive the world in ways no existing technology can — genuinely new ground.
Hardware + AI integration: This is not a pure software play. The work sits at the intersection of proprietary sensing hardware and large-scale ML — a rare combination.
Small, exceptional team: Early-stage, talent-dense, and moving fast. Individual contributions will directly shape the product and the company.
Real-world impact: The systems built here will power applications across robotics, environmental monitoring, agriculture, materials science, and more.
Top-tier backing: Well-funded by leading venture investors with a clear path to scale.

About Harrison Clarke
Harrison Clarke is the search and venture firm that builds engineering teams at VC-backed startups across three disciplines: infrastructure, software engineering, and artificial intelligence. We partner with tier-1 venture capital firms including Sequoia, Sutter Hill Ventures, Menlo Ventures, Greylock, and NEA (amongst others) to place top talent into their portfolio companies as they grow from pre-seed stage through to pre-IPO. Hiring is the foundation of what we do, but it's one part of a broader ecosystem we've built around the founders we work with. We invest into the startups we partner with through Harrison Clarke Ventures. We connect founders with senior technical advisors through our VC network. We produce Inside the Silicon Mind, a podcast featuring the founders and investors shaping the future of technology. And we host curated dinners that bring founders together with engineering leaders, design partners, and potential customers. A founder comes to us for hiring, meets an advisor through our network, gets in front of enterprise buyers at a dinner, and tells their story on the podcast. The companies we believe in most, we invest in.
