Hardware Test Engineer

Hardware Test EngineerAs our Hardware Test Engineer, you will execute the reliability, validation, and verification testing that proves the RELIC across its mechanical, electrical, and compute systems. You will translate the design groups' failure-mode findings into test plans, build the fixtures and instrumentation the tests run on, and carry the results back to the engineers who own the design. Travel: up to 20%.

This is a full-time, in-office role, five days a week in Mountain View.Key Responsibilities:Test Planning & Fixture DevelopmentTranslate DFMEA findings and verification requirements from the design groups, NPI, and the production floor into test plans, sample sizes, stress levels, and acceptance criteriaDesign and build the test fixtures, harnesses, instrumentation, and data acquisition the mechanical, electrical, and compute testing depends onDevelop test procedures and automation scripts in Python or LabVIEW for instrument control, test sequencing, and repeatable per-unit data captureSpecify the chambers, loads, sensors, and bench equipment each campaign requires, and keep them calibrated, documented, and available to the programReliability, Validation & Verification Test ExecutionExecute the reliability test program across HALT, HASS, accelerated life, thermal cycling, vibration, humidity, shock, and burn-in on units and subassembliesRun functional verification and validation from the battery and power electronics through the enclosure, thermal system, and interfaces on EVT, DVT, and PVT buildsExecute the compute and GPU reliability testing together with the GPU infrastructure engineer, covering burn-in, thermal throttling, and telemetry-based failure detectionData Analysis & Failure ReportingCollect and analyze test data using statistical methods, Weibull and life-data analysis, and physics-of-failure reasoningPerform failure analysis and teardown on test and production failures, isolating root cause across the mechanical, electrical, and firmware boundariesProduce test reports carrying the data, the failure evidence, and the specific design or process recommendation to the responsible engineering groupLab, Field & Continuous ImprovementRun and maintain test labs and/or external test house partnerships, including the equipment, fixtures, calibration records, and per-unit test historySupport field failure investigations and the closed-loop corrective action loop, from failure through analysis to corrective action implementationQualifications:Bachelor's degree in Mechanical, Electrical, Mechatronics, or Reliability Engineering (or equivalent industry experience)Experience: 4 to 7 years in hardware test and/or product validation engineering on energy storage, power electronics, grid-tied equipment, or electromechanical hardwareHands-on experience building test fixtures, harnesses, instrumentation, and data acquisition, and bringing a unit up on the bench to be stressed and measuredDirect experience executing environmental and reliability stress testing, including HALT, HASS, accelerated life, thermal cycling, vibration, and humidity, against ASTM standardsProficiency with test automation and data analysis in Python or LabVIEW, and with bench instrumentation including oscilloscopes, data acquisition systems, multimeters, and loadsExperience with failure analysis and root cause methods, and contributing failure-mode evidence to DFMEA and design reviewsWorking knowledge of energy storage and power electronics failure mechanisms, covering cells and battery systems, inverters and converters, thermal management, and outdoor enclosuresComfortable working on the floor alongside assembly technicians and in the field alongside installation crewsExcellent communication skills, with the ability to turn test data into recommendations design engineers will act on
