NDB is seeking a Senior Mechanical Engineer specializing in thermal systems to design and optimize heat management solutions for our nano diamond battery technology. This role focuses on thermal system design including Brayton cycles, heat pipes, cooling systems, encapsulation, and safety design. You will design thermal management systems for battery heat dissipation, develop cooling solutions (heat pipes, phase-change systems, active cooling), conduct thermal analysis and testing, and design safe encapsulation and containment systems. This position requires expertise in thermodynamics, heat transfer, and mechanical system design. Join a team working on breakthrough energy technology that requires innovative thermal engineering solutions. This is an opportunity to apply advanced thermal engineering principles to next-generation nuclear battery systems.
