Mechanical Engineer - Fuel Recycling

Oklo Inc. is developing fast fission power plants and advancing nuclear fuel recycling. They are seeking a Mechanical Engineer to support their nuclear waste treatment systems by developing waste processing equipment and defining mechanical requirements.

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

Requirements:

• 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
• Familiarity with P&IDs, mechanical equipment layouts, process equipment interfaces, material handling concepts, and vendor design packages
• Strong mechanical engineering judgment, including practical understanding of maintainability, reliability, fabrication, inspection, and failure modes
• Experience coordinating work across multiple engineering disciplines
• Ability to produce clear, traceable technical documentation in support of design development, procurement, safety review, or licensing activities
• Experience in nuclear, chemical processing, mining, manufacturing, or other highly regulated industrial facilities
• Experience in commercial nuclear, DOE, advanced reactor, fuel cycle, waste treatment, or high-reliability industrial projects
• Experience with radioactive waste processing, packaging, containerization, storage, or disposal systems in a hot-cell environment
• Experience developing equipment for size reduction, compaction, filtration, solidification, packaging, container handling, drum handling, cask/canister interfaces, or remote/assisted maintenance
• Familiarity with waste characterization, waste acceptance criteria, contamination control, ALARA principles, or radiological work planning
• Familiarity with radioactive waste classification, regulation, or nuclear material packaging requirements
• Experience with design for manufacturability, design for automation, or design for remote handling and maintainability
• Experience with Solidworks
• Experience supporting hazard analysis, failure modes analysis, commissioning, readiness reviews, or startup of industrial process systems
