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:
