About the Job

Requirements

  • A Bachelor of Science degree in engineering or physics is required.
  • At least 2 years of experience in a thermal or mechanical role is required.
  • Experience in thermal analysis and thermally constrained design is required; computational thermal design using finite methods is highly preferred but not required.
  • Proficiency with mechanical computer-aided design is required.
  • A strong problem-solving background and hands-on testing skills are required.
  • Enthusiasm for hardware development, including hands-on design and development in a fast-paced environment, is required.

Responsibilities

  • Mature designs through conceptual, preliminary, and detailed design phases using practical passive and active thermal control techniques.
  • Support design trade studies 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, radio-frequency 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 installation of thermal hardware as needed.
  • Plan and conduct thermal vacuum testing and verification at the component and spacecraft levels.

Desired Qualifications

  • Experience with spacecraft thermal mitigation or printed circuit board thermal mitigation.
  • Computational thermal design experience using finite methods.
  • Experience with Thermal Desktop.
  • Experience with ANSYS Mechanical or ANSYS IcePak.
  • Experience with electronics packaging and printed circuit board design.
  • Experience building and operating high-vacuum systems.
  • Experience designing for a vacuum environment or environments with large temperature swings.

Astranis

Builds small satellites for dedicated internet service

Astranis builds and operates small satellites that supply internet capacity to telecommunications companies, large enterprises, and government customers. Its MicroGEO spacecraft work in geostationary orbit, staying above the same region so customers receive continuous coverage without a large moving constellation. The company designs and manufactures satellites in-house, runs their ground networks, and earns revenue by leasing capacity or managing complete connectivity services. Its infrastructure supports cellular backhaul, aircraft connectivity, and broadband links in remote areas where ground networks are difficult to build. Astranis was founded in 2015 and is headquartered in San Francisco, California.
