Job Description
Process Engineers at Oklo are responsible for the design, engineering analyses, systems engineering, specifications development, and operations of the fluids and power process systems used in Oklo’s power plants and isotope production programs.
Key Responsibilities
- Design fluid and process systems including: piping, valves, compressors, pumps, and heat exchangers for isotope production, recovery, purification, and supporting process systems
- Define process equipment architecture, specifications, operational modes, and performance criteria
- Design, assemble, and operate prototypes to use for iterative design refinement, including bench-scale or pilot-scale process demonstrations
- Generate documentation guiding the system layout, fabrication, installation, commissioning, operation, and maintenance of process equipment with consideration for contamination control, radiological controls, and safe operation
- Serve as process system owner for assigned systems, maintaining their design basis, configuration, and performance throughout the lifecycle
- Prepare technical documentation supporting regulatory filings, safety analyses, and isotope production operations.
- Work with external vendors on process equipment analysis, procurement, and testing
- Develop and maintain process flow diagrams, piping and instrumentation diagrams, mass and energy balances, equipment specifications, and operating envelopes for isotope production systems
- Support isotope product requirements, including yield, purity, traceability, and contamination limits
- Conduct process hazard analyses and implement risk reduction measures addressing equipment and process failure modes, chemical hazards, criticality interfaces, radiological hazards, and abnormal operating conditions
Requirements
- Bachelor's degree in mechanical, chemical, nuclear, radiological, materials, aerospace, petroleum, or a related engineering discipline.
- 5+ years of experience designing, analyzing, or modifying fluid, thermal, or process systems and equipment in nuclear, radiopharmaceutical, isotope production, or related industries.
- Strong understanding of engineering fundamentals, systems design and integration, equipment interfaces, and process system operation.
- Ability to apply process engineering fundamentals to systems involving radioactive materials, chemical separations, gas/liquid handling, thermal management, contamination control, and product quality requirements
- Experience in nuclear, isotope production, radiopharmaceutical, pharmaceutical, laboratory, or related industry.
- Experience with off-gas, ventilation, filtration, vacuum, inert-gas, or controlled atmosphere systems.
- Familiarity with isotope production, radiochemical processing, radiation protection, shielding, contamination control, or ALARA.
- Experience with process prototyping, commissioning, equipment testing, or system ownership.
- We are looking for a Process Engineer that is:
- Passionate about clean energy, making advanced fission a reality, and building a reliable domestic supply chain for critical isotopes
- Able to balance safety, product quality, throughput, reliability, cost, and schedule in engineering decisions
- 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 facilitate discussions on advanced technical subjects with diverse groups and business partners.
- 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.
- 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.
