How to Apply for Fire Protection Engineer

at Oklo

🏢 About Oklo

Oklo is pioneering next-generation fast fission technology with a mission to recycle nuclear waste into clean, reliable energy. Unlike traditional nuclear companies, Oklo focuses on advanced reactor designs that are inherently safer and more efficient. Working here means contributing to groundbreaking technology that could transform the global energy landscape while addressing nuclear waste challenges.

About This Role

As a Fire Protection Engineer at Oklo, you'll build and maintain the entire fire protection program for advanced sodium-cooled fast reactors, from technical documentation to implementation. This role is critical because you'll specifically address unique sodium fire hazards and ensure regulatory compliance for safety-critical systems. Your work directly impacts reactor safety, design decisions, and operational planning for next-generation nuclear technology.

💡 A Day in the Life

A typical day involves reviewing reactor design documents to identify fire hazards, collaborating with mechanical engineers on sodium system layouts, and developing technical basis documentation for fire protection strategies. You might spend time analyzing specific sodium fire scenarios, coordinating with external consultants on specialized analyses, and ensuring all fire protection elements align with both NFPA standards and nuclear regulatory requirements.

🎯 Who Oklo Is Looking For

  • Has 3+ years experience performing fire hazards analyses (FHA) and post-fire safe shutdown analyses specifically in nuclear or high-hazard industrial environments
  • Possesses demonstrated knowledge of sodium fire behavior, suppression methods, and mitigation strategies beyond theoretical understanding
  • Has hands-on experience implementing fire protection programs that meet both NFPA standards and nuclear-specific regulations (NRC, DOE, or similar)
  • Can show examples of cross-disciplinary collaboration with mechanical, electrical, and systems engineers to integrate fire protection into design

📝 Tips for Applying to Oklo

1

Quantify your experience with sodium fire hazards - mention specific projects, mitigation strategies you've implemented, or analyses you've performed

2

Highlight any experience with advanced reactor designs or non-light-water reactor technologies, even if tangential

3

Demonstrate knowledge of both NFPA standards AND nuclear-specific fire safety regulations (10 CFR 50.48, NUREG documents, etc.)

4

Show how you've worked across engineering disciplines by describing specific collaborative projects with mechanical or systems engineers

5

Mention any experience with digital tools for fire modeling or analysis relevant to complex industrial systems

✉️ What to Emphasize in Your Cover Letter

['Your specific experience with sodium fire hazards and mitigation strategies in industrial or nuclear settings', 'Examples of developing or implementing fire protection programs from technical basis through implementation', "How you've successfully collaborated across engineering disciplines to integrate fire safety into design", "Your understanding of Oklo's mission and how your skills advance their next-generation reactor technology"]

⚠️ Common Mistakes to Avoid

  • Only having experience with conventional fire protection in commercial buildings without industrial/nuclear context
  • Treating sodium fires as equivalent to conventional hydrocarbon or electrical fires without addressing unique characteristics
  • Failing to demonstrate understanding of both prescriptive codes (NFPA) and performance-based nuclear regulations
  • Presenting generic fire protection experience without tailoring it to advanced nuclear technology
