• Familiarity with common material degradation mechanisms (e.g., corrosion, creep, embrittlement, fatigue)

• Experience working cross-functionally to support engineering design decisions

• Ability to clearly communicate technical recommendations, including assumptions, risks, and tradeoffs

• Strong written communication skills, including the ability to document technical rationale in a clear and structured manner

Bonus Qualifications:

• Experience in nuclear, aerospace, energy, or other high-reliability industries

• Familiarity with nuclear materials considerations, including radiation effects, sodium environments, or high-temperature systems

We are looking for a Materials Engineer that is:

• Passionate about clean energy 

• Comfortable acting as a technical authority, providing clear recommendations and guiding material selection decisions across a range of applications

• Able to balance engineering rigor with speed, making sound decisions with incomplete information while clearly communicating assumptions and risks

• Skilled at applying first-principles thinking to evaluate material behavior in complex environments

• Experienced in identifying material degradation mechanisms and understanding their impact on system performance and lifetime

• A systems thinker who can build and improve processes that scale material selection across teams, rather than solving one-off problems

• An effective collaborator who can work across disciplines to support design decisions without becoming a bottleneck

• A strong communicator, capable of translating complex material behavior into clear, actionable guidance for engineers and stakeholders

• Detail-oriented, with a focus on consistency, traceability, and defensibility in engineering decisions

• Comfortable operating in a fast-paced, highly iterative environment where priorities may evolve quickly

• Establish, enforce, and continuously improve operational standards, facility procedures, and conduct-of-operations expectations.
• Oversee shift operations, maintenance activities, and engineering support, ensuring coordination across all functional disciplines.
• Serve as the primary onsite authority for operational decision-making, prioritizing nuclear safety, radiological safety, and industrial safety.
• Ensure facility personnel are properly trained, qualified, and performing to defined standards; support development of staffing plans and training programs.
• Monitor facility performance indicators, identify trends, and implement corrective actions to maintain high levels of operational reliability. 
• Support regulatory interfaces, inspections, and audits, ensuring timely resolution of findings and transparent communication.
• Drive a culture of safety, accountability, and continuous improvement throughout the organization.
• Coordinate with senior leadership on operational planning, resource needs, and long-range facility strategy.

Minimum Qualifications:

• Bachelor’s degree in an engineering or science degree. 
• Hold, or have held, a senior reactor operator (SRO) certification/NRC License for similar reactor facility (or equivalent). 
• Minimum of 4 years of supervisory or management experience. Previous commercial nuclear plant or research and test reactor experience is preferred. Education and/or experience that is job-related may be substituted for a degree on a case-by-case basis.

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.

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.
