Thermal Engineer

Astranis•San Francisco, CA

15h•$130,000 - $165,000

About The Position

As an Astranis Thermal Engineer, you will design, evaluate, and test thermal solutions ranging from electronic chips to full spacecraft thermal vacuum tests. The role requires a strong problem-solving background and hands-on testing skills. Experience with spacecraft or printed circuit board thermal mitigation is beneficial but not required.

Requirements

Bachelor of Science degree in engineering or physics.
At least 2 years of experience in a thermal or mechanical role.
Experience in thermal analysis and thermally constrained design.
Proficiency with mechanical CAD.
Passion and enthusiasm for hardware development, including working in a fast-paced environment and participating in hands-on design and development.
U.S. citizenship, lawful permanent residency, or refugee/asylee status, as required to comply with U.S. Government space technology export regulations.

Nice To Haves

Computational thermal design experience using finite methods; highly preferred but not required.
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.
Experience with spacecraft or printed circuit board thermal mitigation.

Responsibilities

Mature designs through conceptual, preliminary, and detailed design phases using practical passive and active thermal control techniques.
Support design trades that balance performance margins, resource use, risk, cost, and schedule.
Perform thermal analysis at varying levels of fidelity, from simplified to detailed, on hardware such as propulsion components, batteries, high-powered electronics, RF components, mechanisms, and printed circuit boards.
Design, evaluate, procure, and test thermal solutions such as heaters, heat pipes, thermal interface materials, and surface coatings.
Develop integration and assembly processes and procedures to ensure thermal design intent is met.
Collaborate with the integration and test team and assist with thermal hardware installation as needed.
Plan and run thermal vacuum testing and verification at the component and spacecraft levels.
