Director of Development Engineering

Oklo Inc. is developing advanced fission power plants, radioisotope supply chains, and nuclear fuel recycling technologies. The Director of Development Engineering will lead civil, site, and nuclear engineering activities for Aurora powerhouse sites, producing technical deliverables that support approvals, licensing, financing, and construction readiness. The role will also manage engineering teams and consultants, oversee site constraints and technical risk reviews, and support isotope production facilities and Nuclear Lifecycle Innovation Campuses.

Responsibilities:

• Lead development engineering across all active sites: site layout, civil/grading design, geotechnical investigation, hydrology, and infrastructure planning
• Solutions engineering for potential co-located buildings such as advanced manufacturing and data centers
• Produce basis-of-design documentation sufficient for project finance due diligence and EPC handoff
• Manage third-party engineering consultants and coordinate with Oklo's internal nuclear design team
• Provide engineering inputs to NRC licensing and NEPA processes coordinated by Oklo's Environmental & Permitting team
• Develop and maintain engineering standards, templates, and quality protocols for the Development organization
• Partner with Oklo’s New Product Integration (NPI) team to translate reactor design requirements, siting criteria, and product evolution into site-specific technical constraints and development scope — ensuring early alignment between product design and site realities
• Develop and own site constraints packages for each Aurora powerhouse development site, synthesizing geotechnical, hydrological, environmental, grid, and regulatory inputs into a single authoritative technical baseline that governs site selection, design, and permitting decisions
• Integrate and quality-control deliverables from civil, geotechnical, environmental, and nuclear engineering consultants — ensuring all third-party work products are consistent, current, and accurately reflected in the site constraints package and project schedule
• Own the development engineering schedule and provide cross-functional technical leadership to identify, prioritize, and mitigate technical risks and fatal flaws on project sites — coordinating with Project Development, Transmission & Interconnection, and Oklo’s Environmental & Permitting team to surface issues early and preserve development optionality
• Lead structured technical risk reviews at each stage gate, evaluating site constraints packages against go/no-go criteria and escalating unresolved fatal flaw risks to the VP of Development with clear options analysis and recommended disposition
• Build and manage a team of engineers across civil/site/electrical and nuclear development disciplines
• Provide engineering support for Isotope production facilities, including facility layout, utility infrastructure design, and integration with co-located Aurora powerhouse systems
• Lead development engineering for Nuclear Lifecycle Innovation Campuses (NLICs), coordinating multi-use site design across power generation, isotope production, and research facility components

Requirements:

• • 12+ years in energy, infrastructure, advanced manufacturing or data center project development engineering, with at least 5 years in a leadership role
• • Strong civil/site engineering background; nuclear project experience highly valued
• • Experience producing engineering deliverables for project financing and EPC handoff
• • Willing and able to learn quickly
• • 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
• 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
• Oklo requires remote employees to travel to headquarters (Santa Clara, CA) twice a quarter annually, based on business or team needs, including attendance at team meetings, off-sites, and other company events or gatherings
• For the first two weeks of onboarding, employees are required to be in person at headquarters in Santa Clara, CA
• Only applicants who meet the definition of a U.S. person under applicable laws may be eligible
• • PE license strongly preferred; experience with DOE or NRC-regulated facilities a significant advantage
