Neutronics Analysis Engineer

Thanks for your interest in Oklo! We are searching for a Neutronics Analysis Engineer to work with our engineering team and help us wrangle the neutrons.

Position Description

The Neutronics Analysis Engineer is responsible for defining, developing, and executing in-core and ex-core neutronics analyses to support reactor design, performance evaluation, and safety assurance. This role involves working closely with the broader design team to solicit and capture requirements, establish the scope of neutronic evaluations, and implement appropriate models and methods. Areas of analysis include, but are not limited to, criticality, depletion, activation, and shielding. The engineer will also support verification and validation activities and contribute to licensing and regulatory interactions by providing technically sound and defensible neutronics analyses.

Specific responsibilities may include:

• Perform the complete range of actions involved in supporting core design and fuel cycle analysis using Monte Carlo and deterministic codes on Oklo reactors.
• Perform calculations and analyses in Monte Carlo based codes such as Serpent, MCNP, SCALE, and OpenMC.
• Perform calculations and analyses with fast reactor deterministic codes such as DIF3D, PERSENT.
• Support the qualification and verification of neutronic analyses, including validation against experiments and benchmarks.
• Be aware of and familiar with fast 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.

Competencies

We are looking for a neutronics 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 SERPENT, MCNP, SCALE and Open-MC
• Skilled with deterministic fast reactor tools, or willing 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

Who you are:

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.
