Overview
Company
Impact
Profile match
Astranis builds small geostationary communications satellites that cost a fraction of a traditional spacecraft. Each satellite serves a single country or region, so an operator buys dedicated bandwidth instead of leasing capacity on a shared platform. The company manufactures at its own facility in San Francisco and has flown missions for customers in Alaska, the Philippines and Mexico.

Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. Today Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe - large enterprises, sovereign governments, and the US military. 

With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts. Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization.

Astranis has raised over $1.2 billion from some of the world’s best investors, including Andreessen Horowitz, Baillie Gifford, Blackrock, Fidelity, Franklin Templeton, and Snowpoint, and employs a team of 500 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.

  • Design, evaluate, procure and test thermal solutions such as heaters, heat pipes, thermal interface materials, and surface coatings
  • Develop processes and procedures for integration and assembly which ensure thermal design intent is met. Collaborate with the integration and test team; provide assistance with the installation of thermal hardware as needed
  • Plan and run thermal vacuum testing and verification at the component and spacecraft level

Requirements

  • Bachelor of Science degree in engineering or physics
  • 2+ years of experience in a thermal/mechanical role
  • Experience in thermal analysis and thermally-constrained design; computational thermal design experience (finite methods) is not required but highly preferred
  • Proficiency with mechanical CAD
  • A passion and enthusiasm for hardware development, including working in a fast-paced environment and hands-on design and development
  • Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria.

Bonus

  • Experience with Thermal Desktop
  • Experience with ANSYS Mechanical or ANSYS IcePak
  • Experience with Electronics Packaging and Printed Circuit Board (PCB) design
