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. Thermal Engineer Intern (Fall 2026)
Internships at Astranis typically last for twelve weeks, and are hourly roles designed for students who are currently enrolled at a four‑year university.
As an Intern, you will have an amazing opportunity to work on hard problems — we pride ourselves on giving everyone at Astranis a chance to do meaningful work on complex projects, no matter their seniority. Many past interns have designed and tested hardware/software that is heading to space on our first satellite, and many of them are now full‑time employees at Astranis.
If you have already graduated from a four‑year university, please apply to be an Associate Engineer.
Work together with the engineering team to design, evaluate, build, and test satellite hardware and/or software.
Support design trades that successfully balance performance margins, resource use, risk, cost, and schedule.
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.
S. in mechanical, aerospace, or equivalent technical degree (e.g. physics or applied math)
