Compensation Overview

Thanks for your interest in Oklo! We are searching for a Thermal-Hydraulics Engineer to join our team.

Position Description

Thermal-Hydraulics Engineers are responsible for playing a crucial role in the design, analysis, and development of our fast reactor systems. You will be responsible for performing thermal-hydraulics analyses, utilizing state-of-the-art codes and methods, and contributing to the qualification and validation of our nuclear thermal-hydraulics analysis tools.

Specific responsibilities may include:

• Conduct systems level analysis using codes such as SAS4A/SASSYS-1, SAM, or GOTHIC.
• Perform subchannel analysis using codes like Pronghorn-Subchannel, DASSH, or COBRA TF.
• Contribute to methods development and code qualification for core thermal hydraulics.
• Participate in verification, validation, and/or commercial grade dedication of nuclear thermal hydraulics analysis tools.
• Collaborate with a multidisciplinary team of engineers to drive the advancement of our fast reactor technologies.
• Generate technical reports and documentation to communicate analysis results and methodologies.

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:

• Bachelor’s, Master’s, or Ph.D. in Nuclear Engineering, Mechanical Engineering, or a related field.
• Proven experience in thermal-hydraulics analysis for nuclear reactor systems.
• Strong problem-solving skills and the ability to work effectively in a collaborative team environment.
• Excellent written and verbal communication skills.

Bonus Qualifications:

• Proficiency in one or more of the mentioned analysis codes (SAS4A/SASSYS-1, RELAP, Pronghorn-Subchannel, DASSH, COBRA-TF) or similar (TRACE, GOTHIC).
• Familiarity with methods development, code qualification, and verification/validation processes in nuclear thermal hydraulics.
