EHS Specialist– Environment, Health & Safety

Oklo Inc. is an advanced nuclear fission technology company developing small, fast fission power plants called Aurora powerhouses, designed to deliver clean, reliable energy directly to customers under long-term power purchase agreements. Beyond power generation, Oklo operates across three interconnected business lines: power generation, nuclear fuel recycling, and production of medical and industrial isotopes, positioning itself as a vertically integrated nuclear energy and materials company. Its reactors are designed to use recycled nuclear fuel, including used fuel and nuclear waste, reducing the need for newly mined uranium and addressing long-standing nuclear waste challenges. The company's mission centers on providing abundant, carbon-free energy to combat climate change while modernizing the nuclear industry through faster deployment timelines, compact reactor designs, and innovative fuel cycles. By recycling nuclear waste into usable fuel, Oklo aims to turn a historical liability of the nuclear industry into a resource, supporting both sustainability goals and energy security. Its isotope production business also supports critical applications in medicine, industry, and scientific research, diversifying its impact beyond electricity generation. Oklo differentiates itself through its compact, fast-spectrum reactor design that can be deployed rapidly (in under a year per site), its direct-to-customer power sales model, and its integrated approach spanning power, fuel, and isotopes. Backed by high-profile investors and leadership, including chairman Sam Altman, Oklo has advanced through regulatory processes with the U.S. Nuclear Regulatory Commission and is pursuing projects across multiple U.S. states, positioning itself as a leader in the next generation of advanced nuclear deployment.

The EHS Specialist is responsible for developing, implementing, and continuously improving Oklo's Environment, Health & Safety programs across our offices, laboratories, test facilities, and future construction and plant sites. You will help build a safety culture that fits a fast-moving advanced fission company, one where safety is a shared responsibility and a driver of excellence rather than a box-checking exercise.

Specific responsibilities may include:

• Develop, maintain, and implement EHS policies, programs, and procedures that comply with OSHA, EPA, state, and local regulations
• Conduct workplace hazard assessments, job hazard analyses, and safety inspections, and drive corrective actions to closure

• Partner with engineering, operations, construction, and licensing teams to embed safety into design, procedures, and daily work
• Track EHS metrics and report on performance and trends to leadership
• Support emergency preparedness and response planning
• Stay current on regulatory developments and industry best practices in nuclear, energy, and industrial safety

Minimum Qualifications:

• Bachelor's degree in Environmental Health & Safety, Industrial Hygiene, Engineering, or a related field (or equivalent experience)
• Minimum 5 years years of experience in an EHS role in industrial, laboratory, construction, energy, or nuclear settings
• Working knowledge of OSHA regulations and environmental compliance requirements
• Experience conducting incident investigations and hazard assessments

Bonus Qualifications:

• Professional certification such as CHST, CSP, CIH, or ASP
• Experience in nuclear, DOE, or NRC-regulated environments
• Experience supporting construction or commissioning of industrial or energy facilities
• Experience building or scaling EHS programs in a startup or high-growth company

Competencies

We are looking for an EHS Specialist that is:

• Technically strong in EHS regulations, risk assessment, and program management
• A practical, solutions-oriented partner who helps teams work safely and efficiently rather than slowing them down
• 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 safety and compliance challenges
• 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

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.
