The job description

Tech stack. Materials degradation mechanisms, irradiation effects analysis, ASME Section II and III, fracture mechanics, corrosion testing, metallography, Python for data analysis

About the role

You will engineer the materials that must survive decades inside a reactor for a utility or vendor organization, understanding how radiation, heat, and chemistry degrade every alloy in the plant. The team evaluates aging mechanisms, qualifies replacement materials, and supports life extension decisions. You will analyze failures, specify materials, and ensure components last their design life. This role matters because material degradation is the fundamental limit on plant lifetime, and your expertise determines whether components are replaced on your schedule or fail on theirs. You will also manage the reactor vessel surveillance capsule program, extracting maximum insight from every withdrawn specimen. Your materials selections for replacement components will balance performance, availability, and cost with the long view the plant requires. You will stay current with industry materials issues through EPRI and owner group participation, applying fleet-wide learning locally. Your failure analyses will be definitive enough to support warranty claims, regulatory responses, and design changes alike. Your specifications will prevent the next failure before the material is ever ordered.

What you will achieve

Complete materials aging evaluations supporting license renewal with technically defensible conclusions.
Resolve material failure investigations with root causes identified and corrective actions preventing recurrence.
Qualify replacement materials and components meeting all code and specification requirements.
Develop aging management programs for critical components that regulators accept without challenge.
Reduce materials-related corrective maintenance 25 percent through proactive degradation management.

What you will bring

Must-haves

2 to 5 years in materials engineering with nuclear, power generation, or high-temperature applications.
Understanding of irradiation effects: embrittlement, swelling, creep, and stress corrosion cracking.
Knowledge of ASME Boiler and Pressure Vessel Code Sections II and III for materials.
Experience with failure analysis methods: fractography, metallography, and mechanical testing.
Ability to specify materials and evaluate supplier qualifications technically.
Familiarity with aging management programs and license renewal requirements.
Clear technical writing for materials evaluations and root cause reports.

Nice-to-haves

Experience with reactor pressure vessel surveillance programs.
Knowledge of advanced alloys for high-temperature or fast reactor applications.
Familiarity with non-destructive examination techniques and their limitations.
Advanced degree in materials science or metallurgical engineering.
