Thanks for your interest in Oklo! We are searching for a Safety Analysis Methods Engineer to join our team.

Position Description:

Safety analysis methods engineers at Oklo are responsible for the development and implementation of safety analysis methodologies to support the licensing of Oklo's reactors. Safety analysis methodologies include those in the areas of transient analysis, source term, and other licensing-related technical areas. This position includes designing and executing engineering analyses, working with team members to generate modeling and simulation results, and clear and thorough documentation of the work.

Specific responsibilities may include:

Responsibilities will differ depending on your background:
  • Developing analytical and computational methods and models
  • Creating and maintaining methodological documentation
  • Interfacing with Oklo's engineering teams to request features, analyses, and interpret results
  • Developing and executing methodologies and analysis for uncertainty quantification and sensitivity analyses
  • Documenting work using modern tools and techniques, and writing well-written, thoughtful technical reports


We are looking for someone that is:
  • Passionate about clean energy
  • Experienced with systems-level thermal-hydraulic analysis
  • Knowledgeable about fast reactor design and analysis methods
  • Willing and able to learn quickly
  • Eager to work on a dynamic team, receive constructive feedback, and grow with us
  • Comfortable in a fast-paced, highly iterative startup environment
  • Excited to think creatively, critically, and reflectively about the problems they are solving, while not leaning only on what has been done before
  • Able to clearly communicate technical content in writing
  • Able to communicate technical content and results verbally

Who you are:

A startup person: You aren't driven by titles or hierarchy, and prefer efficiency to excess process. You don't need or expect to have a lot of guidance but you enjoy working in a fast-paced team. If you prefer the culture and feel of a large organization, that is great, but you likely won't enjoy working with us! There is plenty of important work and plenty of good opportunities with organizations like that.

Motivated: You are self-motivated. You bring an enthusiasm to the team, and imbue a sense of passion that goes beyond clocking in and clocking out. This isn't about a fake or arbitrary "pieces of flair" mentality or lack of work-life balance! It is about being a part of the vision and feeling a part of reaching team goals.

A team-player: Oklo genuinely is a team. We aren't about taking credit for ourselves, and we aren't about pushing blame to others. We do incredible things because we work as a team.

An excellent communicator: We need a person who is not only technically competent but also a clear and upbeat communicator.

Creative: Being creative means that when things fall outside clear scopes or processes or problems arise without clear solutions, you are able to identify it as well as invent ways to solve a problem or fill a need without micromanagement. The successful person in this job will not only be creative, but also enjoy being creative and solving open-ended problems which may change day-by-day.

Detail-oriented: This focus is a big part of excellence, consistency, and quality. Excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.

Minimum Qualifications:

We also think the following are good indicators of qualifications to do this job:
  • Bachelor's degree in engineering
  • Experience in system-level thermal-hydraulic analysis, transient analysis, and nuclear thermal-hydraulic fundamentals
  • Experience in nuclear design and licensing

Bonus Qualifications
  • Experience with uncertainty quantification and sensitivity analyses
  • Experience with SAS4A/SASSYS-1, SAM, GOTHIC, RELAP5, TRACE, MELCOR, or other nuclear system analysis software
  • Fluency with Python
  • Experience with CI/CD computing environments

Salary: $67,000-$144,000

Salary may fall outside of the range provided and will be dependent on applicant experience.

Oklo offers flexible time off, equity, competitive pay, 401k, health insurance, FSA, flexible work hours, and other benefits.
