Responsibilities

• Lead the planning, design, build, commissioning, and operation of the Molten Salt Laboratory including sourcing materials and equipment, mentoring science and engineering teams, and developing molten salt operational experience and expertise
• Define and own the development roadmap for molten salt capabilities including science and engineering workscopes from small pots of static molten salt all the way to large, forced flow integrated effects test loops. Develop the timeline for key prototypical thermal-hydraulic test environments including fabrication methods, corrosion tests, jet nozzle design and testing, and mass and heat exchanger design and testing.
• Partner with other Science departments and with the Engineering and Operations divisions to ensure strong communication, and to align on scientific, engineering, and operational goals for fusion power systems development
• Translate scientific insights, experimental data, and hands-on-experience into design guidance for teams responsible for fusion system architecture
• Evaluate emerging scientific opportunities and integrate advances from academia, national laboratories, and international fusion programs
• Manage relationships with external laboratories, university collaborators, and vendors providing materials, pumps, and fabricated components for high temperature salt systems.
• Establish molten salt laboratory research best practices, documentation standards, review processes, and quality expectations
• Support system troubleshooting, root‑cause investigations, and engineering review of failures or anomalies encountered in development of experimental operations
