Thanks for your interest in Oklo! We are searching for a Radiological Waste Engineering Lead to join our engineering team.
Position Description
Oklo is developing advanced fission power plants and fuel cycle facilities to deliver clean, reliable, and affordable energy at scale. Additionally, Oklo is developing isotope production facilities primarily for medical uses. As our portfolio expands across power generation, fuel recycling, isotope production, and future fuel cycle capabilities, we are seeking an experienced engineer to lead the strategy and technical execution of radioactive waste management across the organization.
The Radiological Waste Engineering Lead owns the development of waste management strategies from concept through operations. This role establishes waste processing approaches, disposal pathways, transportation strategies, waste minimization initiatives, and regulatory interfaces for both reactor and fuel cycle facilities.
You will work closely with process engineering, licensing, operations, safeguards, environmental compliance, construction, and business development teams to ensure radioactive waste considerations are incorporated early into facility and process design rather than addressed later in the project lifecycle.
This position is ideal for someone who enjoys solving first-of-a-kind engineering challenges while building scalable systems that will support multiple future facilities.
Oklo is a fast-moving company where technical leaders are expected to make decisions, challenge assumptions, and help shape company strategy. We are looking for someone who enjoys operating in an entrepreneurial environment and is excited to help redefine how the nuclear industry approaches radioactive waste.
Our ideal candidate is self-motivated, technically excellent, collaborative, and comfortable working across multiple disciplines.
Specific responsibilities may include:
-
Technical Leadership
-
Develop enterprise-wide radioactive waste management strategies for advanced reactors, fuel recycling facilities, isotope production facilities, and supporting infrastructure.

-
Establish onsite waste handling requirements.
-
Lead procurement or development of internal waste tracking system.
-
Develop transportation strategies for radioactive materials and radioactive waste.
-
Evaluate disposal pathways across commercial and government facilities.
-
Lead development and maintenance of commercial waste profiles.
-
Coordinate with disposal vendors and transportation providers.
-
Support waste classification and packaging requirements.
-
Develop cost models associated with long-term waste disposition.
-
-
Cross-Functional Leadership
-
Work closely with engineering, licensing, operations, and environmental compliance
-
Mentor junior engineers and establish best practices for radioactive waste engineering.
-
Develop internal standards, design guides, and engineering procedures.
-
Within your first year, you'll be expected to:
-
Develop Oklo's enterprise radioactive waste strategy.

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.
