# Senior Thermal-Fluids Engineer – Advanced Cooling

We are looking for a Senior Thermal-Fluids Engineer to lead the development of advanced liquid cooling solutions for the thermal management of state-of-the-art semiconductor processing devices (chips), leveraging single-crystal diamond (SCD) for high-performance heat spreading. This role will focus on designing, prototyping, and experimentally validating high-performance cooling architectures, with particular emphasis on jet impingement, spray and microjet technologies, and high heat-flux heat transfer. You will work hands-on from early concepts and modeling through prototype fabrication, testing, and integration with SCD-based semiconductor systems. Responsibilities Lead the design and development of high-performance liquid cooling architectures for SCD-based semiconductor thermal management, including jet impingement, spray, and microjet-based concepts. Model and optimize fluid flow and heat transfer to define jet/nozzle geometries, flow distribution, pressure, temperature, and operating conditions, including single- and two-phase heat transfer regimes. Design cooling hardware for prototyping and manufacturing, incorporating fluid distribution, extraction/return paths, and micr
