Job description

Fuel Performance Engineers at Oklo are responsible for the fuel performance analyses and verification of current and future fuel design for Oklo's Aurora powerhouses. This includes engineering analyses, modeling and simulation, clear and thorough documentation of the analyses, as well as interfacing with our reactor design, fuel fabrication, and licensing teams.

Specific responsibilities may include:

  • Analyzing current and novel fuel design performance across expected operating conditions and postulated off-normal conditions.
  • Devising analysis methodologies that efficiently and effectively build confidence in a design, which can include software development of modeling and simulation tools.
  • Verification and validation of modeling and simulation tools in support of analyses.
  • Supporting experimental fuel campaigns.
  • Collaborating cross-functionally to provide technical feedback to design teams.
  • Documenting work using modern tools and techniques, and writing well-written, thoughtful technical reports.

The difference you'll make

This role contributes to developing fast fission power plants that deliver clean, reliable, and affordable energy at scale, helping establish a domestic supply chain for critical radioisotopes and advancing nuclear fuel recycling to convert nuclear waste into clean energy.

What makes you a great fit

Minimum Qualifications:

  • Bachelor's degree in engineering, plus 3 years of experience
  • Experience with multi-physics system performance analyses
  • Experience with finite element simulation software (e.g., Ansys, Abaqus)
  • Experience with material analysis
  • Experience with object-oriented programming language (e.g., Python, C++)

Bonus Qualifications:

  • Experience with nuclear fuel performance analysis
  • Familiarity with metallic fuels
  • Experience with fuel analysis and fuel performance software (e.g., BISON, LIFE-METAL, etc.)
  • Experience in material selection and material analysis
  • Fluency in Python

Benefits

Salary: $120,000-$165,000 (may fall outside of the range based on experience)
