We are looking for a Mechatronics Engineer who is

• Passionate about clean energy and advanced fission

• Proficient in 2D/3D modeling and CAD for mechanical and robotic systems

• Experienced with electromechanical systems, controls, and automation integration

• Energized by prototyping and deploying real-world hardware

• Creative and persistent when tackling novel engineering challenges

• Comfortable working in a fast-paced, highly iterative startup environment

• A strong communicator, both in technical writing and in collaborative discussions

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.

• Engineering education in mechatronics, mechanical engineering, robotics, electrical engineering, or related discipline

• 5 to 10 years’ experience with automation or robotic system design

• Expert proficiency with CAD software

• Broad familiarity with engineering principles and strong systems integration intuition

• Experience with robotic arms, conveyors, or other automated handling systems

• Experience designing for remote or hazardous environments

• Experience with radiological hot cell environments

• Experience with high-temperature (>500 °C) equipment design

• Familiarity with PLCs, industrial automation, and robotics programming

• Knowledge of GD&T and design for manufacturing

• Experience with simulation tools (e.g., ANSYS, ROS, MATLAB/Simulink)

• Background in nuclear, petrochemical, or pharmaceutical industries with automated systems

• Experience deploying or working on pilot plants or unmanned manufacturing systems

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. For the first two weeks of onboarding, employees are required to be in person at headquarters in Santa Clara, CA.

About Oklo compensation: $100,000–$175,000 (dependent on experience)

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!
