Company Overview Kairos Power is a new nuclear energy technology and engineering company whose mission is to enable the world’s transition to clean energy, with the ultimate goal to dramatically improve people’s quality of life while protecting the environment. This goal will be accomplished through the commercialization of the fluoride-salt-cooled, high-temperature reactor (FHR) that can be deployed with robust safety, affordable costs, and flexible operation to accommodate the expansion of variable renewables. Job Summary Kairos Power is seeking a highly motivated Senior Mechanical Engineer focused on Remote Handling Special Components with expertise in modular hardware design for remotely operated systems. This role is centered on the design, physical integration, and demonstration of remote handling technologies through full-scale mockups and prototype builds. The Senior Engineer will drive 1:1 scale integration efforts to validate interfaces, clearances, tolerances, and handling sequences—systematically derisking reactor maintenance strategies prior to deployment. This position integrates remote handling requirements directly into component architecture and system interfaces to enable efficient assembly, maintenance, inspection, and long-term operability. The role emphasizes hands-on engineering, rapid build-test cycles, and cross-functional collaboration in a highly regulated environment. Responsibilities Modular Maintenance System Development Apply lifecycle design principles including maintainability, inspectability, and decommissioning Integrate remote handling requirements into hardware architecture and system interfaces Develop and maintain interface control documentation supporting plant-level integration Design, build, and evaluate 1:1 scale mockups and integration test articles to validate handling concepts Develop structured test plans and acceptance criteria for full-scale demonstrations Coordinate test readiness reviews with QA and Systems Engineering Implement design updates based on mockup results, demonstrations, and operational feedback Support project planning and cost estimation for integration and testing activities Interface with vendors to ensure manufacturability and feasibility of specialized components Conduct risk and reliability assessments for maintenance systems Ensure compliance with nuclear regulations, safety standards, and applicable codes Maintain configuration-controlled design documentation Remote Handling Solutions Develop remote handling hardware enabling efficient component repair and replacement Lead hands-on design-build-test cycles to mature handling approaches Execute full-scale integration mockups to validate reach, clearances, tooling alignment, ergonomics, and sequencing Collaborate with reactor systems and operations teams to define online and offline maintenance strategies Identify integration risks early and mitigate through rapid prototyping and physical demonstration Testing and Validation Align demonstration opportunities with reactor and facility schedules Develop execution plans for rapid, high-value physical demonstrations Support inspections, installations, shakedown, tuning, and commissioning activities Capture lessons learned from mockups and integration testing to inform future designs Collaboration Partner with engineering, laboratory, shop, and materials teams to execute accelerated hardware development Coordinate cross-disciplinary integration efforts to ensure cohesive system performance Engineering Reports Publish engineering reports documenting design details, mockup results, and integration findings Contribute to design basis documentation and regulatory submittals Team Contribution Share technical knowledge and best practices across the organization Mentor junior engineers in hardware design, integration, and prototype testing Other duties as
