Senior Reliability Engineer (Hardware)

• Lead lifetime reliability modeling for HVAC systems (compressors, motors, electronics, heat exchangers, refrigerant circuits).
• Design and execute lifetime test plans: accelerated cycling, thermal fatigue, electrical endurance, corrosion, vibration, and mechanical stress tests.
• Analyze field reliability data (warranty, service reports, returned units) to refine life models and update design limits.
• Integrate lifetime reliability requirements early in design through DfR methods and cross-functional collaboration.

This role contributes to combating climate change by developing reliable, high-efficiency heat pumps that reduce carbon emissions from home heating and cooling systems, making sustainable living accessible to all.

• BS/MS in Mechanical, Electrical, Materials, or related engineering discipline.
• 7–10+ years in reliability engineering for HVAC or electromechanical systems.
• Expertise in lifetime modeling (Weibull, parametric life analysis, physics-of-failure modeling).
• Strong background in accelerated life testing, test design, and reliability statistics.

• Equity
• Medical/vision/dental/life/disability insurance
• 401k
• Paid parental leave
• Professional Development Stipend
• Commuter benefits
• Flexible PTO
• Estimated salary: $160,000 to $185,000 USD per year + equity

Gradient's mission is to revolutionize home comfort while championing environmental sustainability by combating climate change through high-efficiency, low-carbon heat pumps to decarbonize buildings.
