What you will do

• Own spacecraft- and constellation-level reliability requirements, models, allocations, and probability-of-success and availability targets.
• Define HALT, HASS, accelerated life testing, reliability growth, lot acceptance, and success-run demonstration programs.
• Develop Weibull, Kaplan–Meier, accelerated failure-time, Monte Carlo, probabilistic risk assessment, degradation, and Bayesian reliability models.
• Integrate reliability analysis with program risk management and flow down margins, screening, derating, and test requirements to subsystems.
• Lead root-cause investigations and corrective actions for critical hardware failures, including FRACAS and test-effectiveness tracking.
• Collaborate with design, systems, test, and manufacturing teams; mentor reliability engineers and advise leadership across spacecraft programs.

• Ability to work across hardware design, systems engineering, testing, manufacturing, and program risk management.
• Programming experience in Python or C++ for data analysis, statistical modeling, and reliability calculations.
• Must be a U.S. person under ITAR or otherwise eligible for a federally issued export-control license.

Nice to have

• Master’s or PhD in engineering, materials science, or a related discipline.
• Experience with AFT models such as Norris–Landzberg and Arrhenius, degradation models, Bayesian hierarchical modeling, and MCMC tools.
• Experience with thermal, vibration, and TVAC testing, EEE components, Physics of Failure tools, derating, DFX, and requirements flow-down.
• Experience in a fast-paced startup or new-space environment.

Culture & Benefits

• Work on high-power satellite platforms designed for multiple orbits and deep-space missions.
• Fast-paced, high-growth Series D environment with broad ownership and cross-functional scope.
• Paid time off, medical, dental, and vision coverage.
