Thanks for your interest in Oklo! We are searching for a Senior Mechanical Design Engineer to join our team. We are looking to fill this position immediately.


Mechanical design engineers at Oklo are responsible for the design and verification of structural components. This includes creative conceptual design, engineering analyses, modeling and simulation, selection of materials and manufacturing methodologies, and clear and thorough documentation of the design.

  • Designing and modeling structural components and subsystems.
  • Collaborating cross-functionally to define design requirements, and providing technical feedback to quick-iterating design teams.
  • Identifying deficiencies in mechanical designs and proactively making improvements.
  • Devising analysis methodologies that efficiently and effectively build confidence in a design.
  • Performing engineering analysis, which can include thermal, stress, fatigue, tolerance, safety, manufacturability, and cost.
  • Planning for manufacturing and assembly of components and subsystems.
  • Documenting work using modern tools and techniques, and writing well-written, thoughtful technical reports.


We are looking for a mechanical design engineer that is:
  • Passionate about clean energy
  • Experienced in mechanical design and manufacturing
  • Willing and able to learn quickly
  • Eager to work on a dynamic team, receive constructive feedback, and grow with us
  • 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
  • Able to clearly communicate technical content in writing

Experience level: Intermediate (2-5 yrs) or Experienced (5-10 yrs)

Minimum Qualifications:
  • Bachelor's degree in mechanical engineering
  • Experience designing mechanical systems and products
  • Experience in design for manufacturing
  • Proficiency in a CAD software
  • Excellent math skills

Bonus Qualifications:
  • Experience with engineering simulation software, such as ANSYS
  • Fluency in Python

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 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. Excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.
