  • Build, modify, and maintain test fixtures and evaluation setups.

Lab Operations & Infrastructure

  • Own daily lab operations, including equipment setup, organization, calibration tracking, maintenance, and troubleshooting.
  • Maintain a safe, clean, and ESD-compliant lab environment.
  • Manage lab inventory including cables, probes, fixtures, components, tools, and consumables.
  • Support incoming hardware inspection, labeling, tracking, storage, and controlled checkout/return processes.
  • Help define and enforce best practices for lab usage, equipment handling, safety, and documentation.

Cross-Functional Collaboration

  • Partner closely with chip designers, power electronics engineers, test engineers, digital designers, and operations teams.
  • Support engineering validation and production-readiness activities.
  • Help establish disciplined lab practices.
  • Communicate clearly on test status, lab constraints, equipment issues, and technical observations.

Required Qualifications:

  • 3-5+ years in hardware lab or R&D environment
  • Strong hands-on experience with lab equipment such as oscilloscopes, DMMs, power supplies, electronic loads, function generators, and thermal test equipment.
  • Experience supporting hardware bring-up, debug, validation, or characterization.
  • Strong soldering, rework, and prototype modification skills.
  • Familiarity with at least one automation or data analysis tool such as Python, LabVIEW, MATLAB, or similar.
  • Ability to read schematics, follow test procedures, and understand basic electrical measurements.
  • Strong troubleshooting skills and attention to detail.
  • Comfortable working with high-current, low-voltage, and sensitive electronic hardware.
  • Strong organizational skills and ability to maintain lab discipline in a fast-paced environment.
