Location: Torrance, California, United States; onsite at hirify.global' 145,000-square-foot facility

Salary: $140,000–$210,000 annually, plus equity

Company

hirify.global is a Series C clean-energy and advanced nuclear technology startup developing mass-producible, inherently safe microreactors for terrestrial, underwater, and space applications.

What you will do

• Own quantitative reliability, availability, and capacity-factor analysis for the hirify.global R1 microreactor.
• Translate plant-level performance goals into measurable reliability requirements for mechanical, electrical, controls, thermal, and balance-of-plant systems.
• Develop reliability block diagrams, fault trees, FMEA/FMECA models, failure-rate estimates, and other quantitative reliability analyses.
• Analyze failure modes, degradation mechanisms, component life, maintainability, repair strategies, and the major contributors to reactor downtime.
• Define reliability demonstration and qualification test strategies, including sample sizes, test duration, failure criteria, confidence levels, and statistical acceptance methods.
• Partner with engineering, manufacturing, testing, operations, and deployment teams to drive reliability growth plans and communicate risks to technical leadership.

Requirements

• Bachelor's degree in engineering, applied mathematics, physics, statistics, or a related technical field.
• Experience performing reliability engineering, root cause analysis, failure analysis, statistical analysis, or similar quantitative work on complex hardware systems.
• Working knowledge of statistics, probability, failure modes, and reliability engineering fundamentals.
• Ability to evaluate mechanical and electrical systems, likely failure mechanisms, technical data, and reliability risks.
• Must be eligible under U.S. Government export regulations through U.S. citizenship or nationality, lawful permanent residence, refugee or asylee status, or the ability to obtain required authorizations.

Nice to have

• Reliability engineering experience in nuclear, aerospace, space, automotive, energy, defense, or other safety- or mission-critical hardware industries.
• Experience with reliability block diagrams, fault trees, FMEA/FMECA, Weibull analysis, MTBF/MTTR, probabilistic risk assessment, availability modeling, or reliability growth.
• Knowledge of risk-informed component classification and 10 CFR 50.69.
• Experience with mechanical and electrical design, manufacturing processes, qualification testing, materials, and hardware failure mechanisms.
• Experience using Python, MATLAB, Octave, R, Minitab, SAS, NCSS, or similar tools for engineering and statistical analysis.

Culture & Benefits

• Equity is included in the compensation package.
• Work is centered on complex energy, defense, and space systems with an emphasis on probabilistic, systems-level thinking.
• Teams prioritize in-person collaboration and direct engagement with customers, users, and stakeholders.
• The role supports deep technical work across research, development, manufacturing, testing, and operational learning.
• hirify.global is an equal opportunity employer.
