at Oklo

🏢 About Oklo

Oklo is pioneering the deployment of advanced fast fission technology and nuclear fuel recycling to turn waste into clean energy. As a startup, they offer a fast-paced, mission-driven environment where engineers can directly impact the future of energy.

About This Role

This open call seeks engineers to tackle open-ended problems in developing advanced fission power plants, establishing a domestic radioisotope supply chain, and advancing nuclear fuel recycling. Your work will directly contribute to scaling clean, reliable, affordable energy.

💡 A Day in the Life

You might start your day with a standup meeting to discuss progress on reactor design challenges, then dive into simulations or prototyping for fuel recycling systems. Afternoons could involve cross-functional collaboration with regulatory or supply chain teams, followed by iterating on a technical report or preparing a presentation for a company-wide review.

🎯 Who Oklo Is Looking For

  • Holds a Bachelor's, Master's, or PhD in an engineering field (nuclear, mechanical, electrical, or related) with a strong technical foundation.
  • Deeply passionate about making advanced fission a reality, willing to challenge conventional thinking and propose novel solutions.
  • Excellent communicator who writes in modern active voice and can explain complex technical concepts clearly to diverse audiences.
  • Thrives in a fast-paced startup environment, comfortable with iteration, ambiguity, and working on dynamic, cross-functional teams.

📝 Tips for Applying to Oklo

1

Tailor your resume to highlight experience with nuclear systems, recycling, or radioisotopes—even if from academic projects or internships.

2

In your cover letter, explicitly connect your passion for clean energy to Oklo's mission of converting nuclear waste into fuel.

3

Demonstrate your ability to solve open-ended problems by including a brief example of a novel solution you devised in a previous role or project.

4

Write your application materials in modern active voice—Oklo specifically values this writing style.

5

Proofread meticulously for grammar and spelling errors; the job description emphasizes detail-orientation.

✉️ What to Emphasize in Your Cover Letter

['Express genuine passion for advanced fission and recycling nuclear waste, tying it to your personal or professional goals.', 'Highlight your experience with iterative, fast-paced projects (e.g., startup internships, hackathons, research pivots).', 'Showcase a specific technical problem you solved creatively, emphasizing your ability to work with ambiguity.', 'Demonstrate strong communication skills by writing concisely and actively, and mention any experience presenting technical content to non-experts.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • Study Oklo's technology: their fast fission reactor design and the Aurora powerhouse concept.
  • Understand the current state of nuclear waste recycling in the US and globally—what are the key challenges?
  • Read about the domestic radioisotope supply chain and why it's critical for medical and industrial applications.
  • Familiarize yourself with NRC regulations for advanced reactors and how Oklo is navigating them.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you solved an open-ended engineering problem with limited information—what was your approach?
2 How would you design a system to recycle nuclear waste into fuel? Walk us through your technical thought process.
3 Explain a complex nuclear concept (e.g., fast fission, radioisotope production) to a non-technical audience in 2 minutes.
4 How do you prioritize tasks when working on multiple projects in a fast-paced startup environment?
5 What novel idea do you have for advancing nuclear fuel recycling or reducing waste? Be creative.

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume that doesn't highlight nuclear or energy-related experience—Oklo wants passion for their mission.
  • Using passive voice or overly complex language in your cover letter—they specifically request modern active voice.
  • Failing to show adaptability or comfort with ambiguity; avoid rigid, overly detailed plans that don't allow for iteration.
