From the original posting
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.
As an Astranis 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
- Mature designs through conceptual, preliminary, and detailed design phases using practical passive and active thermal control techniques
- 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; provide assistance with the installation of thermal hardware as needed
- Plan and run thermal vacuum testing and verification at the component and spacecraft level
Requirements
- Bachelor of Science degree in engineering or physics
- 2+ 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
Base pay is just one component of Astranis’s total rewards package. Your compensation also includes a significant equity package via incentive stock options, high-quality company-subsidized healthcare, disability and life insurance, 401(k) retirement planning, flexible PTO, and free on-site catered meals.
