Mechanical Thermal Engineer

Energy is a mission-driven team committed to delivering space-based solar power to the world. We operate at the intersection of space and clean energy, providing continuous baseload power 24/7 without seasonality or the need for batteries. The Mechanical Thermal Engineer will serve as a technical leader responsible for the thermal design, analysis, and testing of spacecraft systems operating in harsh space and ground environments.

Requirements

• Perform spacecraft thermal design and analyses at the board, component, subsystem, and system levels
• Develop spacecraft and subsystem thermal models to predict thermal loads, temperature gradients, and margins for system design
• Lead thermal design and development activities for space-based environments and payload-level integration
• Create and evaluate design concepts using thermal analysis and FEA tools such as Thermal Desktop, ANSYS, or equivalent
• Design passive and active thermal control systems, including heat pipes, radiators, thermal blankets, coatings, heater tapes, and thermistors
• Conduct thermal design and analysis for complex mechanical hardware, including precision mechanisms, electromechanical devices, and electronics packaging
• Support the design, fabrication, and installation of Multi-Layer Insulation (MLI) blankets
• Lead and participate in environmental test campaigns, including thermal vacuum testing and thermal balance testing

Benefits

• Competitive salary and equity
• Medical, dental, vision, disability, and life insurance coverage
• Health and wellness stipend
