Note: The job is a remote job and is open to candidates in USA. Oklo Inc. is developing advanced fission power plants, nuclear fuel recycling technologies, and related nuclear systems. The company is seeking a Mechanical Engineer to develop and integrate radioactive waste treatment equipment from concept through deployment, working with vendors and multidisciplinary teams. The role focuses on defining requirements, evaluating designs, supporting procurement, and delivering practical, maintainable, reliable, and compliant systems for nuclear environments.
Responsibilities
- Develop mechanical requirements, equipment specifications, acceptance criteria, and operating concepts for radioactive waste treatment systems
- Translate process requirements into practical equipment solutions for waste processing, packaging, storage, and material handling
- Evaluate vendor designs for functionality, maintainability, reliability, contamination control, remote operation, and lifecycle performance
- Develop and review equipment layouts, P&IDs, material handling flows, tooling concepts, and mechanical interfaces
- Identify opportunities to simplify designs, improve operability, reduce maintenance burden, and increase production readiness
- Support procurement by finding relevant vendors, preparing technical specifications, evaluating vendor proposals, and reviewing design deliverables
- Lead or participate in multidisciplinary design reviews and drive technical action items to closure
- Develop engineering documentation including design bases, interface definitions, design evaluations, and technical reports
- Support hazard analyses, licensing activities, commissioning, and facility integration
Skills
- Bachelor's degree in Mechanical Engineering or a related engineering field
- Minimum of 5 years of relevant engineering experience
- Experience developing, specifying, integrating, or implementing industrial process equipment
- Experience working with equipment vendors, technical specifications, procurement packages, or design reviews
- Experience with 3D CAD tools, 2D fabrication drawings, equipment specifications, and controlled design documentation
