About Grafton Sciences
We're building physical general intelligence — autonomous systems that can experiment, reason, and discover in the physical world. 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 QA / Metrology Engineer to own precision measurement, inspection, and validation across advanced robotic, electromechanical, and automated systems. You'll run CMMs, profilometers, optical systems, electrical testers, and custom fixtures to verify component accuracy and system performance. This role is deeply hands-on — defining measurement protocols, ensuring calibration integrity, and building the quality infrastructure needed for high-throughput, high-precision engineering.
Responsibilities
- Perform precision measurement and inspection using CMMs, optical systems, profilometers, electrical testers, and custom metrology setups.
- Develop measurement protocols, QA procedures, and verification routines for parts, assemblies, and automated workflows.
- Maintain calibration infrastructure, measurement traceability, and quality documentation for critical hardware.
- Collaborate with mechanical, robotics, electrical, and manufacturing engineers to diagnose issues and improve system performance.
Qualifications
- Strong experience with precision metrology — CMM operation, GD&T, optical/laser measurement, or high-accuracy inspection tools.
- Demonstrated ability to design measurement routines and interpret results across mechanical and electromechanical systems.
- Hands-on debugging instincts and comfort working closely with multidisciplinary engineering teams.
- Detail-oriented, rigorous approach to quality, calibration, documentation, and repeatability in fast-moving environments.
Above all, we look for candidates who can demonstrate world-class excellence.
Compensation
We offer competitive salary, meaningful equity, and benefits.
