Jobs at Oklo Inc

Design, analyze, and specify fluids and power process systems for Oklo power plants. Develop equipment architecture and documentation, build and operate prototypes, support procurement and vendor testing, produce regulatory technical documentation, and own process systems across lifecycle stages.

Oklo seeks passionate engineers to innovate in fast fission technology, emphasizing creativity, teamwork, communication, and adaptability in a dynamic startup environment.

Lead strategy and execution to improve design, prototyping, and manufacturing of nuclear reactor components. Drive process improvements, regulatory compliance (NRC/IAEA), safety and quality, team coaching, vendor oversight, digital tool adoption, and program/budget management while supporting company-wide continuous improvement and travel to sites.

Perform and optimize radiochemical processing, isotope handling, sample preparation, and analytical laboratory work within regulated NRC/DOE frameworks. Support radiological controls, contamination control, dosimetry, documentation, audits, training, commissioning, and mentor junior staff to maintain safe, compliant isotope production and laboratory operations.

Support radiochemistry operations and isotope production in a regulated lab: assist with radiochemical processing, sample prep, analytical measurements, contamination control, documentation, surveys, inventory, procedure reviews, troubleshooting, and cross-functional commissioning and readiness activities.

Perform radiation shielding and transport analyses to support reactor design, plant layout, safety, and licensing. Build source-term, activation, streaming, skyshine, and dose-rate models using Monte Carlo and deterministic tools. Validate analyses against benchmarks and measurements, optimize shielding, document results, and provide technical feedback to iterative design teams.

Lead the requirements management process for complex engineering projects, ensuring clarity and compliance with safety standards and regulations.

Lead design and management of project insurance, surety, and risk transfer programs across development, construction, operations, and decommissioning. Build enterprise project risk frameworks, review contractual risk allocation, support financing and commercial activities, manage brokers/insurers, and present risk reporting to executive leadership and the Board. Collaborate cross-functionally to quantify, mitigate, and transfer complex industrial and nuclear-related risks.

The Human Factors Engineer will develop safety basis documentation and human factors strategies for a nuclear fuel recycling facility, ensuring optimal human-system interfaces and error prevention methodologies.

The Hardware Test Engineer will manage test projects focused on thermo-hydraulic and materials testing, ensuring compliance and quality standards, while leading cross-functional teams.

Lead advanced software engineering efforts for nuclear reactor design and analysis, developing tools for modeling, simulation, and design optimization while mentoring other engineers.

The Senior Process Controls Engineer will design and implement various process control systems, ensuring regulatory compliance and safety while collaborating with cross-functional teams.

The Neutronics Analysis Engineer conducts neutronics analyses for reactor design and performance evaluation, responsible for using Monte Carlo and deterministic codes, validating analyses, and collaborating with design teams.

Lead end-to-end logistics for time-critical Class 7 radioactive products: packaging selection and licensing, carrier and route qualification, shipment execution, contingency planning, hazmat personnel and compliance, and logistics-driven facility and network design to ensure reliable, on-time delivery.

Provide technical quality engineering support for materials, pressure-boundary components, suppliers, and ASME Code compliance. Review and approve CMTRs and supplier documentation, develop Certifying Engineer programs, oversee special processes and inspections, support supplier qualification and audits, resolve nonconformances, and translate code requirements into practical controls to ensure safe, documented, and traceable procurement and fabrication for nuclear projects.

The role involves managing capital project budgeting and cost architecture for nuclear power and related facilities, ensuring cost transparency and governance across projects.

Design core assemblies and components for advanced reactors from concept to final design. Produce 3D CAD models, 2D drawings, BOMs, and specifications in PDM/PLM. Coordinate with analysis, manufacturing, and fuel fabrication teams for validation, DFM/DFA, tolerancing, and manufacturability. Participate in design reviews and improve design processes and documentation.

Support and execute project Quality Assurance and Quality Control per ASME NQA-1 and ANSI/ANS-15.8 across engineering, procurement, construction, inspection, testing, commissioning, and turnover. Perform field inspections, supplier reviews, audits, nonconformance/corrective action management, develop inspection/test plans and quality records, and support supplier qualification and project closeout while collaborating with project and EPC teams.

Lead and supervise project QA/QC across engineering, procurement, construction, inspection, testing, commissioning, and turnover. Implement and assess the project Quality Assurance Program to ASME NQA-1/ANSI standards, lead audits and surveillances, manage supplier and field quality activities, review and approve technical deliverables and nonconformance dispositions, and mentor quality personnel to ensure compliance and completion of project quality records.

Build, implement, and continuously improve a commercial ISO 9001-based Quality Management System. Lead audits, corrective actions, supplier quality, metrics, training, and cross-functional coordination while interfacing with Nuclear Quality Assurance and supporting assessments.
