About the Role
You will develop test capabilities and evidence to assess the reliability of electrical hardware such as PCB assemblies, power supplies, converters and regulators. You will design custom jigs and fixtures, build automated test setups, write Python for instrument control, run accelerated stress tests, and investigate electrical failures together with Systems, Failure Analysis and Design teams.
Requirements
- 5+ years of experience in electrical testing, hardware validation, reliability engineering, or electrical failure analysis
- Ability to turn test requirements into working lab setups
- Strong knowledge of PCBAs, power conversion, voltage regulation and power distribution
- Experience with oscilloscopes, probes, programmable power supplies, electronic loads, multimeters, power analyzers, SMUs and data acquisition
- Proficiency in Python, LabVIEW, or equivalent
- Strong circuit-debugging skills and schematic/PCB layout interpretation
- Understanding of accelerated testing, failure mechanisms, reliability statistics and measurement uncertainty
- Familiarity with JEDEC and IPC test methods
- Ability to collaborate with Systems engineers and manage multiple lab investigations
- BS in Electrical Engineering, Computer Engineering, or related discipline
Responsibilities
- Design, assemble and troubleshoot custom electrical test jigs, fixtures, interface boards, load circuits and wiring harnesses
- Work with the Systems team to establish workloads, power sequencing, interfaces, operating limits and monitoring requirements
- Translate product requirements and reliability risks into test plans
- Build automated test setups integrating programmable power supplies, electronic loads, switching hardware, sensors and data acquisition
- Develop Python or equivalent software for instrument control, test sequencing, monitoring, fault capture and analysis
- Execute accelerated life testing, burn-in, temperature cycling, power/load cycling and temperature/humidity testing
- Establish electrical baselines and monitor changes before, during and after stress
- Investigate electrical failures using schematics, PCB layouts, datasheets and bench measurements
- Reproduce system-level anomalies and correlate results with failure-analysis findings
- Use DOE, statistical reliability analysis and physics-of-failure methods
- Partner with Design, Failure Analysis, Mechanical/Thermal, Quality, Manufacturing and suppliers to validate corrective actions
- Maintain calibrated, repeatable test setups with electrical protection and interlocks
- Document fixture designs, test procedures, results and findings
