Competencies

We are looking for an external hazards regulatory engineer that is:

• Passionate about clean energy
• Passionate about making advanced fission a reality
• Willing and able to learn quickly
• Familiar with industry codes and standards such as IBC and ASCE
• Eager to work on a dynamic team, receive constructive feedback, and grow with us
• 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 modern active voice, so make your cover letter compelling and write it well!
• Able to communicate technical content and results verbally

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.
