Core Design Engineer

Thanks for your interest in Oklo! We are searching for a Core Design Engineer to join our engineering team.

Position Description

Core Design Engineers at Oklo are responsible for designing performant and manufacturable reactor cores which balance neutronic, thermal hydraulic, material, mechanical, and economic considerations. Work performed by Core Design Engineers includes executing multiphysics simulations to assess core performance, writing clear and thorough design documentation, performing analyses to validate and verify core requirements, and working closely with fabrication engineers to mature their designs.

Core design is an interdisciplinary field, we are looking for applicants who have a holistic understanding of reactor physics that lets them quickly ascertain how proposed design changes will impact core performance. Level will be determined based on applicant experience.

Specific responsibilities may include:

Traveling to headquarters (Santa Clara, CA) 2x per calendar quarter for team meetings, company offsite, or other business gatherings

Translating top-level stakeholder requirements into well-written system functional requirements

Modeling core performance over time through multiphysics simulations and first principles approaches

Documenting work using modern tools and techniques, and producing well-written technical reports

Collaborating cross-functionally to define performance requirements, and providing technical feedback to methods development teams

Minimum Qualifications:

Bachelors, Masters, or PhD in nuclear engineering or a related field

Experience with core design from a multidisciplinary perspective

Experience with object-oriented programming language (e.g., Python, C++)

Experience with neutronic analyses

Experience with thermal hydraulic analysis

Experience with material analysis

Bonus Qualifications:

Familiarity with principles of fast reactor core design

Experience with fuel cycle optimization

Familiarity/experience with ternary fuel and ternary fuel cycles

Experience with CI/CD computing environments

Experience with Monte Carlo neutronics tools (e.g., SERPENT, MCNP, SCALE, etc.)

Experience with deterministic neutronics tools (e.g., DIF3D, PERSENT, etc.)
