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, manufacturing, and quality to embed design-for-reliability (DfR) practices across the product lifecycle. 

• Establish reliability metrics, tracking, and reporting to give leadership a clear view of hardware maturity and risk. 

Basic Qualifications 

• Strong understanding of engineering fundamentals. 

• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information. 

• Bachelor's degree in Mechanical, Electrical, Aerospace, Reliability, Industrial Engineering, or a related field. 

• Experience designing and executing reliability test campaigns (e.g., accelerated life testing, HALT/HASS, durability, or component reliability testing). 

• Strong applied statistics for reliability — life-data (Weibull) analysis, reliability demonstration and sample-size determination, design of experiments (DOE), confidence intervals, and acceleration modeling. 

• Proficiency with reliability and statistical tools (e.g., ReliaSoft Weibull++/ALTA, Minitab, JMP, Python, or R). 

• Experience with FMEA/FMECA and reliability modeling methods. 

• Excellent analytical and problem-solving skills. 

• Strong verbal and written communication skills, with the ability to convey technical information to diverse audiences. 

• Ability to work collaboratively in a team-oriented environment. 

Preferred Skills and Experience 

• Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc). 

• Experience in a fast-paced engineering environment or a highly technical role requiring a resourceful, entrepreneurial approach to complete tasks within tight timeframes or budget constraints. 

• Experience in a hardware-intensive industry such as automotive, aerospace/defense, semiconductor, industrial equipment, or energy. 

• Experience building a reliability program or reliability test capability from the ground up. 

• Familiarity with physics-of-failure methods and accelerated stress modeling. 

• Certified Reliability Engineer (CRE) or similar certification. 

• Advanced degrees. 

Additional Requirements 

• Ability to work extended hours and weekends as necessary.
