Senior Thermal Engineer

Company Details

End-to-End Space Transportation and In-Space Services

Thermal engineers apply world-class simulation skills and expert knowledge of heat transfer to solve complex cross-discipline problems encountered during launch vehicle design, development, and operations. Intense thermal radiation, aeroheating, cryogenics, and vacuum culminate in a complex thermal problem with a wide array of solutions.

Thermal engineers will deconstruct these complex issues to ensure Firefly vehicles meet customer requirements and conform to external safety standards, while reducing margin and driving future evolution of the vehicle thermal systems.

RESPONSIBILITIES

  • Determines effective thermal analysis approaches to provide quantitative and clear answers to functional, performance driven thermal questions.
  • Owns vehicle level thermal models (FEM, CFD) of the complete launch vehicle.
  • Creates detailed submodels for key thermal environments to capture effects of ablation, plume radiation, and other challenging phenomena.
  • Develops well documented codes or procedures for performing thermal analysis, and postprocessing analyses and test results. We want to develop the tools and methods to empower all engineers at
  • Firefly to account for thermal effects.
  • Responsible for updating and correlating models based on heat transfer data from test
  • Documents analysis and test for review by responsible engineers, peers, customers, and launch authorities
