Job summary

Xcimer Energy, based in Denver, CO, seeks a Molten Salt Scientist for an on-site, full-time role to drive the molten salt research program. Lead the lab design, experimental campaigns, and collaboration across science and engineering teams to advance fusion system technology.

You will define a roadmap for molten salt capabilities, oversee high-temperature fluid experiments, and translate results into concrete design guidance for scalable fusion power systems.

Qualifications

• PhD in Mechanical, Nuclear, Chemical Engineering or closely related field.
• 8+ years of experience in experimental high-temperature fluids (molten salts or liquid metals), experimental R&D, or technology development for complex nuclear or fusion systems.
• Demonstrated hands-on laboratory experience and ability to establish a new experimental capability from the ground up.
• Experience designing and executing experiments that raise component or system technology readiness.
• Demonstrated leadership of multidisciplinary scientific or R&D organizations.

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 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 Engineering and Operations to align on 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.
