Location: Minimum of 3 days a week in the office in Torrance, CA.
About The Role
We are seeking a highly experienced Principal ATE Test Engineer to lead test development and production test strategy for a high-performance integrated voltage regulator (IVR) semiconductor product line targeting advanced AI and HPC power delivery applications.
This role is focused primarily on semiconductor test engineering, spanning DFT collaboration, characterization support, wafer probe, final test, hardware development, production ramp, and manufacturing optimization. The ideal candidate combines deep technical expertise in mixed-signal and power semiconductor test with strong leadership across silicon bring-up and high-volume manufacturing environments.
The candidate is expected to operate as a senior technical leader capable of driving test strategy independently across internal teams and external manufacturing partners.
What You Will Do
- Define overall manufacturing test strategy for IVR silicon across wafer probe and package final test
- Develop production screening methodologies for:
- Analog and mixed-signal circuits
- Integrated ADCs and telemetry
- Digital control and state machines
- PMBus/I2C interfaces
- OTP/eFuse programming
- Protection and fault-management circuitry
- Power-stage functionality and efficiency
- Partner with Design and DFT teams to ensure robust testability and manufacturability
- Lead development of wafer sort and final test solutions on production ATE platforms, including:
- ATE Test programs
- Probe/load board hardware
- Calibration methodologies
- Thermal management approaches
- Multisite test architectures
- Drive aggressive test time reduction while maintaining production quality targets.
- Support transition from engineering characterization flows into scalable high-volume production test
- Support first-silicon bring-up activities and debug of manufacturing test flows
- Support trim development, calibration algorithms, and production limit setting
- Debug silicon, hardware, and software issues observed during characterization and manufacturing ramp
What You Bring
- 10+ years in the semiconductor industry, with a proven track record developing manufacturing test solutions for high-volume semiconductor products.
