Thanks for your interest in Oklo! We are searching for an Industrial Hygienist to join our team.

Position Description

The Industrial Hygienist is responsible for industrial hygiene programs across active nuclear and construction job sites to ensure compliance with OSHA, NRC, DOE, and other applicable federal and state regulations. This role also supports broader Environmental, Health, and Safety (EHS) initiatives, contributing to the development and implementation of site-wide safety programs, risk assessments, and compliance strategies. The position includes developing and delivering training programs to educate employees and contractors on industrial hygiene practices, hazard recognition, and EHS requirements. The role involves building scalable health and safety infrastructure as operations expand across multiple sites, with a focus on program development, data analysis, cross-functional coordination, training, and supporting overall EHS performance and culture.

Specific responsibilities may include:

• Exposure Assessment & Monitoring

  • Design and execute industrial hygiene sampling plans (airborne contaminants, radiation adjunct hazards, noise, heat stress, etc.)

  • Conduct routine and incident-driven exposure assessments across construction, commissioning, and operational environments

  • Interpret and communicate results, recommending controls where needed

• Regulatory Compliance

  • Ensure compliance with OSHA standards (e.g., HAZWOPER, respiratory protection, hazard communication) and NRC-related worker safety requirements

  • Support development and maintenance of written programs (IH plans, chemical hygiene plans, respiratory protection, PPE, etc.)

  • Prepare for and support audits, inspections, and regulatory interactions

• Hazard Identification & Control

  • Partner with EHS, Engineering, and Operations teams to identify workplace hazards and implement controls using the hierarchy of controls

  • Evaluate new processes, materials, and equipment for potential health risks

  • Support Job Hazard Analyses (JHAs) and pre-job planning for high-risk activities

• Field Support & Site Engagement

  • Maintain strong on-site presence to support construction and operational teams

  • Provide real-time guidance during field activities, outages, or non-routine work

  • Build trust with frontline teams to drive proactive safety culture

• Program Development & Scaling

  • Help build and standardize IH programs across multiple sites as the company grows

  • Implement systems for exposure tracking, record-keeping, and reporting

  • Help build and support integration of IH considerations into broader EHS and operational processes

• Training & Communication

  • Deliver training on IH-related topics (chemical safety, respiratory protection, noise, heat stress, etc.)

  • Translate technical findings into clear, actionable guidance for non-technical audiences

  • Promote awareness of occupational health risks and prevention strategies

• Incident Response & Investigation

  • Support investigations related to exposure incidents or near misses

  • Conduct root cause analyses and recommend corrective actions

  • Collaborate with medical and safety teams as needed

Minimum Qualifications:

• Bachelor’s or Master’s degree in Industrial Hygiene, Occupational Health, Environmental Health & Safety, or related field

• 5+ years of industrial hygiene experience in high-hazard environments (nuclear, energy, construction, manufacturing, or similar)

• Strong knowledge of OSHA regulations and industrial hygiene best practices; familiarity with NRC/DOE environments strongly preferred

• Experience supporting active job sites (construction, commissioning, or operations)

Bonus Qualifications:

• Professional certification (CIH) strongly preferred or in progress

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.
