Administering the NCS program, methodologies, and management measures

Competencies:

Knowledge of nuclear science, physics of criticality, and chemistry

Knowledge of the nuclear fuel cycle and nuclear fuel cycle facility accident scenarios

Ability to perform criticality calculations by hand or using criticality codes (e.g., SCALE, MCNP) for CSEs

Familiarity with critical experiments and their purpose

Knowledge of criticality-specific codes, standards, regulatory requirements, and industry practices for nuclear fuel cycle facilities

Minimum Qualifications:

Bachelors, Masters, or PhD in nuclear engineering, chemical engineering, or chemistry

Experience performing CSEs as a part of a nuclear facility safety basis

Proficient with MCNP and SCALE codes

Bonus Qualifications:

3+ years of experience performing criticality safety evaluations for an NRC licensed fuel cycle facility

Familiarity with ANSI/ANS-8 standards

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. Even excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.

About Oklo compensation: $85,000-$165,000 annually.

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