About the job
Leads the design, validation, and contract-manufacturer deployment of precision PCBA test fixtures and infrastructure for robotic systems.
What you'll do
- Own mechanical architecture and design of PCBA test stations, fixtures, and interchangeable tooling.
- Build, test, and debug fixtures; establish acceptance checks for alignment, force, repeatability, wear, and safe operation.
- Manage fabrication partners and deploy fixtures at contract manufacturers, providing documentation, training, and troubleshooting.
What they ask for
- Independently deliver precision-fixture or equipment projects from ambiguous requirements through design, fabrication, validation, and sustained use.
- Strong 3D CAD and released-drawing skills, including fabrication and assembly packages, bills of materials, and revision control.
- Strong fundamentals in GD&T, tolerance analysis, locating schemes, stiffness, compliance, contact forces, and load paths.
- Hands-on fabrication-partner collaboration, fixture assembly and measurement, failure diagnosis, hardware iteration, and acceptance-check execution.
Nice to have
- Degree in Mechanical Engineering, Mechatronics, Robotics, or a related field, or equivalent practical experience.
- PCBA test-fixture experience; ESD-aware tooling, thermal interfaces, actuated fixtures, interlocks, or structural and thermal simulation; NX, SolidWorks, or Creo.
