  • Communicate analytical results and effects of design changes on component and system performance
  • Review and interpret test data to assess performance at system and component level, and anchor analytical models
  • Author analysis reports and supporting documentation for design reviews
  • Lead data and test readiness reviews and contribute to design reviews
  • Provide peer reviews for thermal and fluid analyses conducted by ZBO team colleagues
  • Create work plans, document progress, and report status to leads and managers
  • Develop test plans and procedures for component, subsystem, and integrated cryocooler testing
  • Execute test procedures involving pressurized cryogenic and non-cryogenic fluid systems
  • Ensure work meets Blue Origin policies and procedures

Minimum qualifications
