# Senior Molten Salt Engineer

Description SHINE is seeking a Senior Molten Salt Engineer to support two of our product lines: transmutation of used nuclear fuel (UNF) and fusion power. The US has more than 95,000 metric tons of used nuclear fuel and nowhere to put it; transmutation reduces the long-lived actinides that drive its long-term radiotoxicity. Fusion power plants need a blanket that breeds its own tritium and carries heat out of the machine. Both depend on molten salts - chlorides for transmutation, fluorides for the fusion blanket - and on engineers who can make them pure, keep them that way at temperature, and keep them from corroding the systems that hold them. The Senior Molten Salt Engineer owns SHINE’s molten salt capability, from the glovebox to the pilot system. Key responsibilities include preparing and purifying chloride and fluoride salts; designing, building, and operating salt test loops and experimental rigs; generating the salt chemistry, property, and materials data that the designs depend on; and turning those results into design requirements for the transmutation and fusion blanket systems. The role then carries salt-wetted systems through preliminary and detailed design, working wit
