About The Role

You will be the technical lead for thermal verification activities across the Nyx program. You own spacecraft-level thermal test campaigns, including Thermal Vacuum (TVAC) and Thermal Balance testing. You will support 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, and 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 for the Nyx 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
  • Ensure TCS verification activities remain aligned with program priorities, schedules and risks

Support Flight Model Integration and AIT

  • Work alongside AIT teams during spacecraft assembly and integration
  • Define thermal instrumentation strategies and test configurations
  • Support installation, verification and troubleshooting of thermal hardware
  • Participate in integrated spacecraft functional testing
  • Support leak testing, functional testing, fluid loop commissioning and system check-outs

Drive Thermal Test Data Exploitation

  • Support pre-test thermal predictions
