Strike Engineer

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.

Thanks for your interest in Oklo! We are searching for a Strike Engineer to join our engineering team.

Position Description

The Strike Engineer is a senior, highly adaptable engineer who reports to the Engineering Strike Team Lead and takes ownership of Oklo's highest-priority, most ambiguous technical problems. This person moves between programs, builds context quickly, reduces problems to first principles, and stays accountable through verified resolution. Depending on the need, the Strike Engineer may serve as a hands-on individual contributor, technical lead, or interim manager. They establish a durable path, help staff the work, transfer ownership to the right long-term team, and then take on the next priority.

Specific responsibilities may include:

• Embed in high-priority engineering programs and rapidly develop a working understanding of the system, constraints, stakeholders, and current failure modes.
• Define problems from first principles by separating facts from assumptions, identifying the governing physics and interfaces, and reducing uncertainty to testable questions.
• Work hands-on across design, analysis, prototyping, testing, manufacturing, software and data, systems integration, and field execution as the problem requires.
• Establish a practical execution plan with owners, decision points, schedule, risks, and objective completion criteria, then drive the work through verified closure.
• Diagnose technical and operational failures using data, experiments, direct observation, and disciplined root-cause analysis.
• Make sound engineering tradeoffs under uncertainty while accounting for safety, regulatory requirements, quality, cost, schedule, operability, and manufacturability.
• Temporarily lead a project or team when needed by clarifying priorities, coordinating cross-functional work, removing blockers, and communicating decisions and risks.
• Help recruit and onboard permanent owners, then transfer stable scope with clear documentation, open risks, decisions, and next steps.
• Create reusable tools, processes, design standards, or technical documentation when they will prevent recurring problems or accelerate future work.

Minimum Qualifications:

• Bachelor's degree in engineering, physics, or a related technical field, or equivalent practical experience.
• 2 or more years of experience solving complex engineering problems from definition through design, execution, validation, and handoff.
• Technical breadth across multiple engineering domains and deep expertise in at least one area such as mechanical, electrical, controls, software, systems, manufacturing, test, thermal-fluid, structural, or nuclear engineering.
• Demonstrated ability to reason from first principles, challenge unsupported assumptions, and validate conclusions with analysis, tests, or operating data.
• Hands-on ability to use the tools needed to move work forward, which may include modeling, CAD, calculations, test equipment, scripting, data analysis, or prototyping.
• Experience leading cross-functional technical work without relying on formal authority, including stepping into temporary management responsibilities when needed.
• Strong written and verbal communication, including concise decision records, technical plans, risk summaries, and executive-level updates.

Bonus Qualifications:

• Experience in the nuclear industry, advanced reactor development, commercial power generation, national laboratories, or another safety-critical energy environment.
• Experience delivering hardware or integrated systems in a regulated, high-consequence, or quality-controlled environment.
• Experience starting a new program, recovering a stalled project, or resolving a persistent technical or operational problem.
• Experience with hardware-software integration, automation, controls, data systems, or test infrastructure.
• Experience hiring, developing, or onboarding engineers and transferring work to a durable long-term owner.

Competencies

We are looking for a Strike Engineer who is:

• Able to move across systems, mechanical, electrical, controls, software and data, manufacturing, and test work, while recognizing when specialist depth is required.
• Able to change altitude quickly, from detailed technical work to project leadership and temporary people management, without losing clarity or accountability.
• 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 technical problems
• 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.
