Responsibilities
Execute thermal and fluids testing from component-level characterization (e.g., valves, pumps, fans, heat exchangers, insulation materials) through full thermal-system validation
Develop test plans and Design-of-Experiments (DoE) in partnership with thermal analysis and mechanical design teams—turning hypotheses into crisp pass/fail criteria and learning goals
Define instrumentation plans to ensure we’re measuring what matters (temperatures, pressures, flows, ΔP, thermal resistances, transients)
Design fixtures and rigs; procure and integrate test equipment including thermocouples/RTDs, pressure sensors, flowmeters, anemometers, DAQs
Size and integrate plumbing for support equipment (chillers, pumps, fans, reservoirs, filters, fittings, hoses, quick disconnects) to enable safe, repeatable testing
Own end-to-end bench build quality: layout, plumbing, grounding/EMI considerations near power electronics, safety interlocks, and maintainability
Automate test execution, data logging, and post-processing to enable repeatable test campaigns and fast iteration loops
Build data analysis workflows that produce actionable outputs (not just raw logs): clear plots, summaries, and 'what changed / why it matters' reporting
Drive root cause and failure analysis when tests go sideways: reproduce, instrument deeper, isolate failure mechanisms, and validate corrective actions
Close the loop with design engineering—ensuring fixes are verified and regression-proof
Qualification
Required
A degree in Mechanical Engineering or related fields, with background in thermodynamics or fluids engineering
>2 years of industry or research experience in a lab environment with proven hands-on experience in testing and developing test fixtures
