Hardware Test Engineer

Test Planning & Fixture Development

• Translate DFMEA findings and verification requirements from the design groups, NPI, and

the production floor into test plans, sample sizes, stress levels, and acceptance criteria

• Design and build the test fixtures, harnesses, instrumentation, and data acquisition the

mechanical, electrical, and compute testing depends on

• Develop test procedures and automation scripts in Python or LabVIEW for instrument

control, test sequencing, and repeatable per-unit data capture

• Specify the chambers, loads, sensors, and bench equipment each campaign requires, and

keep them calibrated, documented, and available to the program

Reliability, Validation & Verification Test Execution

• Execute the reliability test program across HALT, HASS, accelerated life, thermal cycling,

vibration, humidity, shock, and burn-in on units and subassemblies

• Run functional verification and validation from the battery and power electronics through

the enclosure, thermal system, and interfaces on EVT, DVT and PVT builds

• Execute the compute and GPU reliability testing together with the GPU infrastructure

engineer, covering burn-in, thermal throttling, and telemetry-based failure detection

Data Analysis & Failure Reporting

• Collect and analyze test data using statistical methods, Weibull and life-data analysis, and

physics-of-failure reasoning

• Perform failure analysis and teardown on test and production failures, isolating root cause

across the mechanical, electrical, and firmware boundaries

• Produce test reports carrying the data, the failure evidence, and the specific design or

process recommendation to the responsible engineering group

Lab, Field & Continuous Improvement

• Run and maintain test labs and/or external test house partnerships, including the

equipment, fixtures, calibration records, and per-unit test history

• Support field failure investigations and the closed-loop corrective action loop, from failure

through analysis to corrective action implementation

• Education: Bachelor’s degree in Mechanical, Electrical, Mechatronics, or Reliability

Engineering (or equivalent industry experience)

• Industry Experience: 4 to 7 years in hardware test and/or product validation engineering on

energy storage, power electronics, grid-tied equipment, or electromechanical hardware

• Hands-on experience building test fixtures, harnesses, instrumentation, and data

acquisition, and bringing a unit up on the bench to be stressed and measured

• Direct experience executing environmental and reliability stress testing, including HALT,

HASS, accelerated life, thermal cycling, vibration, and humidity, against ASTM standards

• Proficiency with test automation and data analysis in Python or LabVIEW, and with bench

instrumentation including oscilloscopes, data acquisition systems, multimeters, and loads

• Experience with failure analysis and root cause methods, and contributing failure-mode

evidence to DFMEA and design reviews

• Working knowledge of energy storage and power electronics failure mechanisms, covering

cells and battery systems, inverters and converters, thermal management, and outdoor

enclosures

• Comfortable working on the floor alongside assembly technicians and in the field alongside

installation crews

• Excellent communication skills, with the ability to turn test data into recommendations
