Reliability Engineer

About the Company General Matter enriches uranium. We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US. In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume. Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way. Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society. We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  We are a mission-driven company with a culture of urgency, accountability, and transparency. Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. About This Role As a Reliability Engineer at General Matter, you'll own the reliability of the hardware we build. You'll design and lead the test campaigns that tell us how our systems hold up over their life — how they fail, when, and why — and bring the analytical rigor to make those answers trustworthy. This is a hands-on, systems-level role embedded closely with our test organization: you'll turn requirements into test plans, make sense of the results, and feed what you learn back into design so reliability is built in rather than discovered late. As General Matter scales, you'll help lay the foundation for a dedicated reliability test capability. Responsibilities Design and lead accelerated life test (ALT), life-leader, and component reliability test campaigns across our hardware. Develop reliability test plans that map applied stresses to field conditions using appropriate acceleration models. Perform the statistical analysis that determines test article quantities, sample sizes, test durations, and confidence/reliability targets (e.g., reliability demonstration testing, Weibull/life-data analysis, sudden-death testing). Define and allocate reliability requirements across systems and components. Analyze test and field data to characterize failure modes, life distributions, and reliability growth. Lead failure analysis and root-cause investigations and drive corrective actions to closure. Develop and maintain reliability models and artifacts — FMEA/FMECA, reliability block diagrams, fault trees, and life predictions. Work embedded with test engineering to execute campaigns, instrument test articles, and interpret results. Partner with design,…
