Lead design and analysis of thermal management and aerothermal systems for spacecraft and hypersonic reentry vehicles. Responsibilities include thermal and mass transfer analysis, material and supplier selection, thermal protection design, CAD ownership, hardware integration, and qualification testing. The role oversees TVAC and supports arc jet testing while balancing performance, mass, cost, manufacturing, and vehicle integration constraints.

Designs, analyzes, prototypes, tests, and documents mechanical hardware for spaceflight bioinstrumentation, including electromechanical and microfluidic systems. Responsibilities include CAD modeling, engineering drawings, rapid prototyping, mechanical analysis, DFM reviews, fabrication, manufacturing transition, and assembly, integration, and testing of flight systems. The role requires hands-on hardware development, materials expertise, and experience with polymers, machining, CAM, and analysis software such as ANSYS.

Lead the design and development of spacecraft electrical power systems, including solar power, batteries, high-voltage PMAD, PCDUs, EMI filtering, and power electronics. Develop prototypes, schematics, PCB layouts, and flight hardware; perform testing, debugging, qualification, and environmental validation. Establish design standards, lead DFM reviews, guide hardware through integration and test, manage technical risks, and support manufacturing transition and formal design reviews.

Designs and analyzes thermal management and aerothermal systems for spacecraft, satellites, payloads, and hypersonic reentry vehicles. Responsibilities include CAD assemblies, heat and mass transfer analyses, material selection, thermal budgets, thermal protection systems, supplier evaluation, hardware integration, and TVAC testing. The engineer also supports arc jet testing, high-temperature materials development, qualification activities, and technical projects from concept through implementation while balancing performance, mass, cost, and manufacturing constraints.
