## Job description

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.

#### Thermal Engineer Associate (Winter 2027)

Associate Engineer positions typically last for twelve weeks, and are salaried roles designed for students who have already received a bachelor's degree (or who will have done so before working at Astranis). 

As an Associate Engineer, 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, and our Associate Engineers work on projects that are of equal importance and difficulty to the projects we give our full-time employees. Many past Associate Engineers have designed and tested hardware/software that is heading to space on our first satellite, and many now work at Astranis full-time. 

If you are still a college student, please apply to join us as an Intern.

#### Role

-   Work together with the engineering team to design, analyze, 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.
-   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

-   Have a four-year degree 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
-   Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria.

#### 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 salary for this position is $1,925 per week.
