About Grafton Sciences We’re building AI systems with general physical ability — the capacity to experiment, engineer, or manufacture anything. We believe achieving this is a key step towards building superintelligence. With deep technical roots and real-world progress at scale (e.g., a $42M NIH project), we’re pushing the frontier of physical AI. Joining us means inventing from first principles, owning real systems end-to-end, and helping build a capability the world has never had before.
About The Role We’re seeking a Senior RL and Physical / Robotics Systems Engineer to build the environments, verifiers, and physical-process models that allow agents to learn and operate in the real world. You’ll work across robotics, ML, simulation, and physical experimentation to develop high-fidelity RL environments, evaluation frameworks, and automated verification systems. This role is ideal for someone who has worked deeply with hardware and robotics while also building ML systems for control, planning, or physical process optimization.
