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.

• Perform thermal analysis to varying degrees of fidelity (simplified to detailed) on a variety of different types of hardware such as propulsion components, batteries, high powered electronics, RF components, mechanisms, and printed circuit boards (PCBs).
• 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 in the installation of thermal hardware as needed.
• Plan and run thermal vacuum testing and verification at the component and spacecraft level.

Requirements

• Currently pursuing a B.S. or M.S. in mechanical, aerospace, or equivalent technical degree (e.g. physics or applied math)
• A passion and enthusiasm for hardware development, including working in a fast-paced environment and hands‑on design and development
• Demonstrated ability to personally design, build, and test hardware from scratch.
• US Citizenship or Green Card

Bonus

• Experience with CAD
• Experience with analytical software thermal analysis such as ANSYS and Thermal Desktop
• Experience with electronics systems design and packaging
• Experience (projects or previous internships) related to aerospace

The base pay for this position is $29.00 per hour.
