Senior Reliability Engineer – High-Temp Energy Systems

NextGenEnergyJobs; Austin, Northern (TX, KY); Hybrid; USD 110,000 - 170,000; Full time

Job summary

Exowatt is transforming energy for the AI era with its P3 system, integrating thermal storage, heat exchangers, and power electronics to deliver on-demand electricity. We seek a Reliability Engineer to own life-testing programs and drive design improvements.

The role requires 5+ years in electromechanical reliability, expertise in FMEA, FRACAS, and Weibull analysis, and the ability to build reliability models. Austin-based, on-site collaboration with cross-functional teams is essential.

Qualifications

• Bachelor's degree in Mechanical, Aerospace, Electrical, or related field.
• 5+ years of reliability engineering experience with electromechanical or thermal hardware.
• Experience with ALT/HALT/HASS testing and reliability analysis methods (FMEA, FRACAS, Weibull).

Responsibilities

• Own reliability requirements, targets, and budgets for P3 system hardware — thermal storage, heat exchangers, turbomachinery, power electronics, and balance-of-plant components
• Design and execute accelerated life testing (ALT), HALT, and HASS programs to validate component and system life under thermal cycling, vibration, and operational stress conditions representative of the P3 deployment environment
• Lead FMEA and reliability-centered maintenance (RCM) studies during design, NPI, and production ramp; track and close action items with cross-functional teams
• Analyze field failure data, warranty returns, and in-service performance data to identify failure modes, estimate Weibull parameters, and prioritize design or process improvements
• Own the FRACAS process — capture, analyze, and close out failures from test and field with design and manufacturing partners
• Collaborate with design engineering on reliability-by-design principles: derating, thermal margin, fatigue life, creep, and materials selection for high-temperature, long-duration operation
• Build and maintain reliability models (RBD, fault trees, MTBF/MTTF estimates) and support system-level availability analysis for customer site deployments
• Define and track reliability KPIs — field MTBF, infant-mortality rates, demonstrated vs. predicted reliability — and report to engineering and operations leadership
• Partner closely with the Quality Engineering team to connect supplier and manufacturing quality data to field reliability outcomes
