• Operating software interfaces and automated test equipment to exercise and validate electrical hardware.
• Setting up, calibrating, and operating thermal and vibration chambers.
• Troubleshooting test failures and determining whether issues are related to the device under test (DUT), test equipment, harnesses, or test setup.
• Supporting the development, commissioning, and validation of automated test systems.
• Reviewing and documenting test results, failures, and root-cause findings.

• Operate software user interfaces to control test equipment during hardware bring-up and testing.
• Validate system functionality using laboratory equipment such as oscilloscopes, power analyzers, power supplies, and digital multimeters.
• Set up and operate thermal and vibration chambers for environmental testing.
• Perform calibration and mechanical setup of chambers, chillers, fixtures, and associated test equipment.
• Troubleshoot and root-cause failures involving DUTs, test equipment, electrical harnesses, and test fixtures.
• Perform hands-on electrical testing and hardware validation.
• Build and support automated test equipment (ATE) and industrial automation systems.
• Support commissioning and validation of new test systems.
• Perform circuit board modifications, including component rework, soldering, and de-soldering.
• Read and interpret electrical schematics, drawings, and manufacturer datasheets.
• Build first-article test systems and redline schematics as required.
• Document test procedures, test results, equipment issues, and failure investigations.
• Support reliability and manufacturing testing at internal facilities, external laboratories, and contract manufacturing facilities.
• Understand and apply EVT, DVT, and PVT development processes and tester validation practices.
• Perform basic calculations related to control and ramp rates to determine required test profile durations.

• Strong hands-on troubleshooting and problem-solving skills.
• Ability to read and understand electrical and digital schematics.
• Understanding of basic digital electronic components and circuit functions.
• Experience operating laboratory test equipment, including oscilloscopes, multimeters, power supplies, and power analyzers.
• Knowledge of thermal and vibration chamber operation and setup.
• Experience with chambers, chillers, fixtures, and mechanical test set-ups.
• Understanding of automated test equipment and industrial automation systems.
• Ability to troubleshoot DUT, test equipment, harness, and fixture failures.
• Strong documentation and technical communication skills.
• Ability to analyze test data and clearly communicate test results.
• Understanding of hardware development cycles, including EVT, DVT, and PVT.
• Knowledge of tester validation and test-system commissioning.
• Ability to use power tools and perform mechanical assembly.
• Experience with soldering, de-soldering, and circuit board rework.
• Strong organizational skills and attention to detail.
• Ability to work effectively with engineering leads, technicians, vendors, and cross-functional teams.
• Hands-on approach with the ability to proactively identify and resolve gaps in test setups.
• Proficiency with Microsoft and Google productivity applications, including spreadsheets, word processing, and presentations.

• Technical degree in Electronics, Electrical Engineering, Mechanical Engineering, or a related field, or equivalent relevant experience.
• 5+ years of experience building automated test equipment (ATE) or industrial automation systems.
• Experience performing electrical testing using standard laboratory equipment.
• Experience with thermal and/or vibration test chambers.
• Experience with electrical schematics, drawings, and manufacturer datasheets.
• Experience with soldering and circuit board rework.
• Experience using power tools and performing mechanical assembly.
• Experience supporting hardware bring-up, reliability testing, manufacturing testing, or test-system commissioning preferred.
• Automotive electronics or ECU testing experience is a plus.
• Experience working with ADAS, telematics, infotainment, battery management, or zonal ECU hardware is a plus.
