Spacecraft Thermal Engineer

Here at The Exploration Company, we are building innovative aerospace technologies that advance the future of space transportation. We are seeking an experienced Spacecraft Thermal Verification Engineer to join our Thermal Control System team. You will be the technical lead for the preparation, execution and exploitation of thermal verification activities by test across the Nyx program. You will own spacecraft-level thermal test campaigns, including Thermal Vacuum (TVAC) and Thermal Balance testing, support AIT with the Thermal Control System Flight Model integration and verification, coordinate thermal qualification activities with other sub-systems, and ensure compliance with spacecraft verification requirements. You will work closely with System Engineering, AIT, Test facilities, Program, Avionics and Propulsion. You will be part of the TCS & ECLSS Team and will report to the Principal Thermal Control System Engineer. Key Responsibilities Lead Thermal Vacuum and Thermal Balance Campaigns Define test objectives, verification logic and success criteria of the Nyx system TVAC campaign Develop test plans, test procedures and operational concepts with other functional chains and AIT Prepare and lead Test Readiness Reviews, Test Review Board and NCR Board Lead test logic and execution of spacecraft, subsystem and components thermal test campaigns. Drive anomaly and NCR investigations and technical decision-making during testing. Present campaign status and recommendations to project leadership. Deliver test reports and verification evidence packages Own Thermal Test Verification Strategy Ensure thermal requirements are properly verified through test, inspection or demonstration. Build and maintain verification events. Drive verification closure toward Qualification Review and Flight Readiness Review. Support Technical Reviews, Design Reviews and Qualification Reviews.
