Fusion Energy and Light Isotope Science, Group Manager

People Development and Culture Building Recruit, develop, mentor, and retain a high-caliber technical staff. Identify and grow the next generation of technical leaders within the group. Reinforce the division's operating culture, values, and norms around scientific rigor, collaboration, psychological safety, inclusion, and accountability at the group level. Set the day-to-day tone for how the group works together. Create an environment where researchers are supported, developed, and enabled to do their best work. Manage performance, allocate staff and resources across the group's project portfolio, and make sound personnel and investment decisions. Foster a strong safety culture and ensure all group work — including tritium handling, byproduct materials handling, and other radiological research activities — is planned and executed safely and in full compliance with environmental, safety, health, quality, and security requirements. Ensure appropriate handling of the chemical and mixed hazards associated with fuel cycle and blanket research — including beryllium, lead, lithium, fluorides, and hydrides — alongside radiological hazards such as tritium and activated materials, coordinating with the appropriate SRNL facilities and partners, including the Advanced Manufacturing Collaborative (AMC) , where fabrication and materials work is performed using surrogate materials. Science and Infrastructure Stewardship and Execution Work with the ESE Division Director to translate division and SRNL strategic priorities into the group's technical portfolio and resource allocation. Steward the quality, rigor, and reputation of the group's work across its core domains — hydrogen isotope and fuel cycle science, tritium processing and validation, light isotope technologies and production (e.g., helium-3 recovery, heavy water/deuterium production and purification, lithium/boron isotope separation), and high-radiation-environment operability. Serve as a credible technical voice to sponsors, peers, and the external research community. Coordinate with the fission community on joint challenges such as molten salts, tritium extraction, liquid metal systems, and other synergistic technologies. Synergize tritium-materials interaction research with the fusion materials community, ensuring that functional materials for fuel cycle technologies are developed and tested through progressions with hydrogen isotopes to enable fuel cycle, blanket, and other fusion technologies. Apply SRNL’s maturity-staged development pathway to fusion-relevant conditions — surrogate research (protium/deuterium) for rapid, low-cost development, followed by tritium research to validate concepts under the continuous, high-throughput, plasma-relevant regimes that distinguish the fusion fuel cycle. Support isotope production missions by applying the group's separations, handling, and processing expertise to the recovery and supply of light isotopes (e.g., helium-3, deuterium) needed for fusion, defense, and other strategic applications. Integrate modeling, analytical, and experimental methods to solve challenges such as tritium accountancy, integrated full-plant modeling, and digital-twin simulations. Identify high-value opportunities that align with DOE mission needs (FES, ARPA-E, OTC, etc.) — including the fuel cycle challenge area named in the DOE Fusion Science and Technology Roadmap — SRNL strategic priorities, and the group's distinctive capabilities, and bring them forward to inform division and directorate strategy. Ensure the group has the test infrastructure, equipment, talent, and partnerships needed to execute effectively and on time, while also sequencing capability investments along where the science is headed. External Partnership and Ecosystem Development Cultivate strategic partnerships outside DOE — fusion developers, industry, universities, and other national laboratories — that strengthen the group's capabilities and expand its funding base and impact. Grow the fusion fuel cycle capability as a national hub, bringing regional universities and private industry into cost-sharing partnerships that advance hydrogen isotope research, workforce development, and next-generation fuel cycle technology. Collaborate with the fusion community and provide input on fusion regulations, fusion nonproliferation, and fusion codes and standards, as well as modeling and communication around tritium emissions and accident scenarios. Lead and mentor staff in building and deepening these relationships, positioning the group as a credible, trusted partner to fusion developers, industry, and academia. Work with partners in academia and industry to support workforce development efforts, including development of educational materials, support for seminars, and broader support of the fusion ecosystem created by FC-FIRE and other FIRE collaboratives and other collaboration mechanisms. Advance SRNL's standing and visibility in fusion fuel cycle and isotope science through publications, presentations, and professional leadership. Support the Division Director, SEI Program Office, and Directorate in engaging relevant DOE program offices (e.g., Fusion Energy Sciences, ARPA-E, OTC), translating those relationships into a healthy, diversified project portfolio. Operational Excellence and Business Performance Manage the group's budget, financial performance, and facility and infrastructure needs, including capital planning for fuel cycle test infrastructure. Ensure delivery on scope, schedule, and budget. Establish group-level metrics, reporting cadences, and accountability structures. Track and communicate progress to the Division Director and SEI Program Office. Work within the SRNL matrix structure to align group capabilities with program priorities, surfacing challenges and opportunities that should inform division and directorate strategic planning.
