Job description

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

Position Description: We are seeking a skilled Safety Analysis Engineer to support the development of the safety basis for a first-of-a-kind used nuclear fuel recycling facility. You will support the identification and evaluation of hazards/accidents, the designation of Items Relied On For Safety (IROFS), and the development of management measures. Additionally, you will support radiological, subcriticality, chemical, and fire safety programs.

Specific responsibilities may include:

• Develop and maintain safety basis documents according to applicable Nuclear Regulatory Commission regulation and guidance
• Support Integrated Safety Analysis (ISA), Criticality Safety Evaluations, Fire Hazard Analysis (FHA), and Natural Phenomena Hazard (NPH) analysis
• Identify and evaluate radiological, criticality, chemical, fire, and natural phenomena hazards
• Identify and evaluate accident sequences using both inductive and deductive methods
• Perform deterministic consequence severity calculations for radiological/chemical source term and dose
• Perform likelihood calculations using qualitative and semi-quantitative (e.g., layers of protection analysis)
• Designate items relied on for safety (IROFS) for the prevention and mitigation of accidents
• Develop management measures to ensure adequate availability and reliability of IROFS

Competencies:

We are looking for a Safety Analysis Engineer that is:

• Passionate about clean energy
• An optimist at heart
• Passionate about making advanced fission a reality
• Willing and able to learn quickly
• Willing to think differently and do things in new ways
• 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
• Willing to propose novel and creative solutions to technical problems
• An excellent writer who can write in a modern active voice, so make your cover letter compelling and write it well!
• Able to communicate technical content and results verbally

Minimum Qualifications:

• Bachelor’s degree in chemical engineering, mechanical engineering, nuclear engineering, or related discipline; a master's or Ph.D. is highly desirable
• 3-5 years of experience in experience in nuclear safety, process safety, or similar high-hazard environments.
• Hazard and Operability Study (HAZOP) and Failure Modes and Effects (FMEA) PHA methods

Bonus Qualifications:

• NRC licensed fuel cycle facility safety basis development
• Consequence severity analysis using RADTRAD, MELCOR/MACCS, ARCON and PAVAN
• Event tree and fault tree analysis
• NUREG-1513, NUREG-1520, NUREG-1718 and relevant regulatory frameworks

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.
