Thank you for your interest in Oklo We are searching for aNeutronics Engineerto join our radioisotopes team.
Position Description:
The Neutronics Engineer is responsible for performing reactor design calculations that include core design and fuel cycle analyses. Other work includes the design of irradiation targets for radioisotope production and how those targets affect the local and macro reactor core system (self-shielding, fuel consumption, production yield, etc.)
Specific responsibilities may include:
- Perform the complete range of actions involved in core design and fuel cycle analysis using Monte Carlo and deterministic codes on Oklo/Atomic Alchemy reactors. These include core design, core sizing, core optimization, reactivity feedback, core lifetime, and criticality analyses, among others.
- Perform calculations and analyses in Monte Carlo based codes such as MCNP, Serpent, and OpenMC.
- Perform calculations and analyses with deterministic codes such as CASMO/SIMULATE or HELIOS.
- Be aware of and familiar with research reactor core design and analysis work being performed internationally, as well as related benchmark calculations and experiments being performed internationally.
- Provide technical feedback to quick-iterating design teams.
- Document work using modern tools and techniques, and write well-written, thoughtful technical reports.
We are looking for a Neutronics Engineer that is:
- Passionate about making advanced industrial-scale radioisotope production
- Knowledgeable about research 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
- Passionate about making "radioisotope shortage" a bygone phrase
- An optimist at heart
- 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
Intermediate (2-5yr) or Experienced (5-10yr)
Minimum Qualifications:
- If you have experience and expertise in reactor design, apply We also think the following are good indicators of qualifications to do this job: Bachelors, Masters, or PhD in a technical field, such as nuclear engineering, with experience in reactor design and analysis (Masters or PhD may be preferable)
- Fluency with Python
- Experience with modern object oriented languages, preferably C++
- Proficiency with high performance computing systems
- Proficiency with MCNP and SERPENT is highly recommended
- Hands-on experience in a reactor setting. Not required, but it is a bonus to not have purely theoretical/modeling experience.
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. Even excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.
About Oklo travel requirements:
Oklo requires remote employees to travel to headquarters (Santa Clara, CA) twice a quarter annually, based on business or team needs, including attendance at team meetings, off-sites, and other company events or gatherings.
About Oklo compensation: $102,000-$190,000
Oklo offers flexible time off, equity, competitive pay, 401k, health insurance, FSA, flexible work hours, and other benefits.
We are looking to fill this position immediately
About Oklo Inc.: Oklo Inc. is developing fast fission power plants to deliver clean, reliable, and affordable energy at scale; establishing a domestic supply chain for critical radioisotopes; and advancing nuclear fuel recycling to convert nuclear waste into clean energy. Oklo was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel material from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission. Oklo is also developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and U.S. National Laboratories.
#CHOP: Oklo's Values
Collaboration: We go further, together. We bring diverse perspectives, listen actively, and build trust through transparency and respect. We work across disciplines, sharing ownership to turn complex challenges into shared successes.
Humility: We are team players who act for the good of the company and for the world. We are focused on our mission, not personal recognition.
