• 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

• Currently pursuing a B.S. or M.S. 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 pay for this position is $29.00 per hour.
