TL;DR · Senior Thermal Engineer

The Sr. Thermal Engineer (Starlink) joins the team responsible for the world’s largest satellite broadband system. This role involves the thermal design, test, and validation of all Starlink hardware, including phased array antennas, custom silicon design for chips, consumer WiFi, and various RF systems. You will own every component and interface, performing thermal analysis to improve hardware performance in extreme environments ranging from Antarctica to high-speed flight. Key responsibilities include designing semiconductor packages, running lab tests to validate performance, and automating workflows to reduce engineering investment. Required skills include thermal analysis and modeling experience, while preferred qualifications include proficiency in MATLAB, Python, Thermal Desktop, ANSYS Workbench, Flotherm, and Icepak. You will also utilize 3D modeling and 0-D and 1-D thermal/fluid networks to solve complex engineering problems.

What you'll do

  • Design thermal systems for next-generation phased arrays, gateways, and consumer wireless products.
  • Perform thermal design for semiconductor packages from high-level concepts to detailed simulations.
  • Build and run tests to validate hardware performance in extreme environmental conditions.
  • Automate workflows and simplify operations to reduce engineering investment during the design cycle.
  • Use a first-principles approach to evaluate sizing cases and the impact of design decisions.
  • Analyze hardware performance to provide specific recommendations for robustness improvements.
  • Produce high-quality documentation for all design requirements and technical specifications.

What we're looking for

  • Bachelor's degree in an engineering discipline.
  • 5+ years of experience in thermal analysis and modeling.
  • Must be a U.S. citizen, national, lawful permanent resident, refugee, asylee, or eligible for Department of State authorization.
  • Master's degree in a relevant engineering discipline (preferred).
  • Experience using scientific programming languages such as MATLAB or Python (preferred).
  • Experience with Thermal Desktop and ANSYS Workbench (preferred).
  • Experience with 3D modeling and 0-D and 1-D thermal/fluid networks (preferred).
  • Experience with tools like Flotherm or Icepak (preferred).
