How to Apply for Senior Software Engineer
at Oklo
🏢 About Oklo
Oklo is pioneering next-generation fast fission technology to recycle nuclear waste into clean, reliable, and affordable energy. Unlike traditional energy companies, Oklo focuses on advanced reactor design and multiphysics simulations to transform nuclear energy. Working here means contributing directly to solving climate change through innovative nuclear technology.
About This Role
This Senior Software Engineer role involves architecting systems for storing/reactor data at scale, owning CI/CD pipelines for complex multiphysics simulations, and developing tools for reactor engineers to visualize and optimize designs. You'll directly impact reactor development by creating reproducible simulations and enabling data-driven design decisions that advance clean energy technology.
💡 A Day in the Life
You might start by reviewing simulation results from overnight reactor physics runs, then collaborate with reactor engineers to improve visualization tools for design comparisons. Afternoon could involve architecting enhancements to CI/CD pipelines for multiphysics analyses or mentoring junior engineers on best practices for reproducible simulations.
🚀 Application Tools
🎯 Who Oklo Is Looking For
- Has 8+ years experience building scalable data systems and CI/CD pipelines, preferably in scientific computing or engineering domains
- Demonstrates deep Python expertise and Git proficiency with experience in multiphysics simulations or scientific computing
- Shows proven ability to own projects end-to-end while mentoring engineers and setting technical direction
- Possesses strong communication skills for collaborating with reactor engineers and cross-functional teams on complex technical problems
📝 Tips for Applying to Oklo
Highlight specific experience with multiphysics simulations, scientific computing platforms, or nuclear/energy sector software development
Showcase projects where you designed CI/CD pipelines for complex computational workflows with emphasis on reproducibility
Demonstrate how you've enabled engineers or scientists through visualization tools or data platforms in previous roles
Include examples of mentoring junior engineers and contributing to engineering culture in technical organizations
