Mechanical Test Automation Engineer (CAD & Fixture Design) for a Wireless Charging Test Team with a Global Consumer Electronics Company in Cupertino, CA

A wireless charging test team in Cupertino is looking for a Mechanical Test Automation Engineer to design and refine the fixtures, nests and jigs that hold a wide range of charging accessories for robotic test runs. The main focus is mechanical and CAD work. Python is used only for light script maintenance, because an in-house developer owns the test framework. You’ll work in a shared makerspace with electrical engineers, software developers and program managers.

Responsibilities:

• Design custom test fixtures, nest plates and alignment jigs in 3D CAD for a range of wireless charging accessories
• Prototype and iterate on fixtures with 3D printing and light fabrication, then assemble and calibrate them
• Integrate actuators, stages and sensors into test benches built for reliable, unattended overnight runs
• Adjust test tunables and maintain existing Python scripts as needed
• Run charge stability, regression and protocol tests on Qi, Qi2 and magnetic charging setups
• Find the root cause of electromechanical and firmware issues, and write clear bug reports for cross-functional teams

Key Qualifications:

• BS in ME, Mechatronics, EE or a related field (or equivalent experience), with 3+ years testing electromechanical or embedded systems
• Strong 3D CAD skills (SolidWorks, NX or similar) for fixture and jig design
• Hands-on rapid prototyping (3D printing, light fabrication) and actuator/sensor integration
• Experience isolating defects across hardware, firmware and software
• Working Python skills for editing and maintaining test scripts
• Clear written and verbal communication, including test plans and bug reports

Nice to Have:

• Familiarity with Qi, Qi2 or MagSafe (training provided)
• USB-PD experience
• Instrument control (SCPI, VISA, Serial) with power supplies, electronic loads and DAQs
• Robotics or motion-stage automation experience
• Git, HIL pipelines, SQL or test telemetry dashboards

Location: Cupertino, CA (onsite, Monday–Friday)

Duration: 12 months

Pay Rate: $55/hr
