About the Team

Our Robotics team is focused on unlocking general-purpose robotics and pushing towards AGI-level intelligence in dynamic, real-world settings.

About the Role

We are seeking a Mechanical Engineer for a senior individual-contributor role leading printed circuit board assembly (PCBA) test fixtures and infrastructure for advanced robotic systems.

Responsibilities

• Own the mechanical architecture of PCBA test stations, including frames, board nests, datum schemes, access, guarding, ergonomics, and serviceability.
• Design probe and bed-of-nails fixtures, connector-mating mechanisms, board supports, clamps, and interchangeable tooling for programming, functional test, and characterization.
• Use first-principles analysis and simulation to assess stiffness, probe and insertion forces, board deflection, tolerance stacks, thermal growth, and fixture life; validate key predictions on hardware.
• Develop locating and compliance features that accommodate board and assembly variation, protect components and solder joints, and preserve contact repeatability across loading cycles and board revisions.
• Partner with electrical engineers on test-point access, probe selection, connector engagement, ESD provisions, cable routing, cooling, and interlocks; define motion and sequencing constraints with software and controls partners.
• Build, assemble, instrument, and debug fixtures in the lab. Establish acceptance checks for alignment, force, board strain where needed, contact repeatability, and cycle life; separate fixture problems from board failures.
• Design safe loading, pinch-point protection, hard stops, and operator access for manual or actuated fixtures. Make wear components easy to inspect, clean, and replace.
• Manage fabrication partners and component vendors. Release CAD, drawings, bills of materials, tolerance analyses, assembly instructions, inspection plans, and maintenance procedures.
• Own fixture deployment and acceptance at contract manufacturers, including assembly and alignment checks, correlation with lab fixtures, operator training, and troubleshooting.

Requirements

• Demonstrated ability to independently deliver significant precision-fixture or equipment projects from ambiguous requirements through detailed design, fabrication, validation, and sustained use.
• Strong 3D CAD and released-drawing capability, including complete 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 ability to work with fabrication partners, assemble and measure fixtures, diagnose failures, and iterate hardware in a lab or manufacturing environment.

Preferred Qualifications

• Degree in Mechanical Engineering, Mechatronics, Robotics, or a related field, or equivalent practical experience.
• Prior PCBA test-fixture experience with board nests, probe or bed-of-nails fixtures, connector mating, and protection of delicate electronic assemblies.
• Experience with ESD-aware tooling, thermal interfaces, actuated fixtures, interlocks, or structural and thermal simulation.
• Experience with NX, SolidWorks, Creo, or equivalent tools; robotics hardware; or fixture replication and new-product builds at contract manufacturers.
