Software Engineer; Applied AI​/ML

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

Join us in pioneering the next generation of nuclear reactors! You'll leverage your software skills alongside nuclear engineers to model, simulate, design, and deploy advanced fission power technology. You will work at the forefront of the nuclear industry, developing novel techniques to reach new levels of safety, efficiency, and resiliency. Come be a part of powering the future with advanced fission power plants to provide clean, reliable, affordable energy.

Oklo is a fast-moving startup where you will be responsible for tackling a wide range of challenges in deploying nuclear systems. A nuclear background is not required, but a healthy curiosity and eagerness to learn are essential in this role.

• Invent and implement practical LLM-based workflows to accelerate Oklo’s business and engineering processes.
  • Ensure rigorous security and information control.
  • Accelerate both engineering and non-technical workflows.
• Design, implement, deploy and maintain production machine learning models for the design and analysis of nuclear systems.
• Develop surrogate models for use in real-time digital twins.
• Grow and manage a team of software engineers to support your AI initiatives.
• Present roadmaps, product demos, and progress updates to senior leadership.
  • Ensure their departments' needs are met by your initiatives.
  • Solicit user feedback from individual contributors and department leadership.

• Bachelor’s degree in Computer Science, Electrical Engineering, Math, Physics, or equivalent software engineering experience.
• Managing and/or integrating AI into large, corporate data ontologies.
• Leading company-wide initiatives (from project inception to delivery and maintenance).
• Physics-informed machine learning (surrogates, symbolic encodings, digital twins).
• Python fluency.
• CI/CD pipelining.
• Git proficiency.
• Growing small software organizations.
• Working with large data collection pipelines.
• Optimization, statistics and design of experiments.

• Rust development
• Typescript/Java script (especially Svelte) development
• Git Lab CI/CD
• Growing and managing teams of software engineers.
• Navigating sensitive, controlled, or externally regulated data.
• Knowledge of and excitement for a nuclear-powered future.
• Navigating quality assurance and compliance requirements with AI.
• Nuclear engineering concepts (reactors, power generation, fuel performance, fuel recycling, etc.)

We are looking for a Software Engineer that is:

• Passionate about clean energy
• Passionate about making advanced fission a reality
• Willing and able to learn quickly
• [Knowledgeable about fast reactor design]
• [Highly skilled with Monte Carlo neutronics tools such as MCNP, SERPENT, and Open-MC]
• [Skilled with deterministic fast reactor tools, or wiling and eager to learn]
• 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…
