Technical Fellow, Instrumentation and Controls

X-energy, LLC is seeking a Technical Fellow - Instrumentation and Control (I&C) to serve as the company’s technical authority on instrumentation for the Xe-100 high-temperature gas-cooled reactor (HTGR). The successful candidate provides guidance, sets the standards, reviews and approves the work of others, and provides authoritative technical judgment across the instrumentation lifecycle - from measurement concept through procurement, factory testing, and site commissioning.

While primarily consulting, reviewer, and approver role, the Fellow is expected to perform hands-on work as needed to establish expectations, demonstrate standards, and provide worked examples that define the expected rigor and quality of instrumentation engineering. A central dimension of the role is deep experience developing modes of operation for first-of-a-kind technology, ensuring that instrumentation and control approaches are grounded in how a novel plant will actually be operated.

• Serve as the senior technical authority and design approver for instrumentation across the Xe-100 program, applying deep expertise in sensor technologies, associated hardware, installation schemes, setting the direction for developing new sensors and installation methods where existing solutions are inadequate
• Provide expert guidance on the development of detailed description on operating modes and states for first-of-a-kind technology
• Ensuring instrumentation and control approaches are driven by, and consistent with, the plant’s concept of operations - review and approving how measurements and protective functions map to each operating mode and transition
• Review and approve instrument technology selections and the associated redundancy and voting schemes proposed by the engineering team, based on measurement inputs from system designer/process engineer
• Develop standards, guidance documents and approve installation schemes for standard measurements, including additional hardware for installation
• Guide and approve the development of technology selection and installation schemes for non-standard and first-of-a-kind measurement technologies
• Establish specification standards and review/approve sensor and instrument specifications prepared for procurement, ensuring they are clear, complete, and fit for purchasing and supplier engagemen
• Lead or oversee the technical evaluation of received instrument quotes and approve supplier recommendations for specific measurement technologies based on that evaluation
• Advise purchasing and support organizations on the technical aspects of procuring and delivering instruments and associated hardware packages to site on schedule
• Provide oversight and expert support for instrument testing at the factory, at site, and at other stages, reviewing test approaches and results to confirm performance against specification
• Provide expert consultation and selective hands-on support for instrumentation-related installation and commissioning at project sites, helping resolve field issues and confirming as-installed performance meets expectations
• Provide senior I&C expertise into power plant controls development, including review and guidance on control hardware for the investment protection system and the reactor protection system
• Provide guidance for safety analysis workshops and efforts e.g. HAZID/HAZOP/LOPA etc.
• Act as a technical mentor and cross-functional influencer - elevating the I&C capability of the broader engineering organization, defining quality and rigor expectations, and guiding systems engineering, design, licensing, procurement, and project teams through expertise rather than positional authority
