• Build strong interfaces with safety, licensing, and regulatory teams to ensure test programs provide defensible results.

• Mentor and grow a high-performing test engineering team, fostering a culture of rigor, creativity, and accountability.

• Bachelor’s degree in mechanical, nuclear, electrical, or related engineering discipline.

• At least 10 years of experience in test engineering, with increasing responsibility in leadership or management.

• Experience in developing and executing test programs in highly regulated industries (nuclear, aerospace, defense, or similar).

• Familiarity with instrumentation, data acquisition systems, and facility operations.

• Demonstrated track record of delivering complex test programs.

• Master’s degree or PhD in a relevant engineering field.

• Prior experience supporting regulatory submittals with test data.

• Familiarity with Siemens Teamcenter or other PLM/requirements traceability tools.

• Strong network within the test engineering and facility operations community.

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.
