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. As an Astranis Senior Thermal Engineer, you will design, evaluate and test thermal solutions ranging from electronic chips to full spacecraft thermal vacuum tests. You must have a strong problem-solving background as well as hands-on testing skills. Experience with spacecraft or printed circuit board thermal mitigation are benefits but not required. Role Identify feasible thermal architectures and mature designs through conceptual, preliminary, and detailed design phases using practical passive and active thermal control techniques. Take charge of 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. Mentor and support junior engineers. Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team. Requirements Bachelor of Science degree in engineering or physics 5+ 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 Experience building and operating high vacuum systems Experience designing for a vacuum environment or environments with large temperature swings What we offer: All our positions offer a compensation package that includes equity and robust benefits.
