You will be a core driver of the detailed thermal design of spacecraft subsystems by running thermal analysis at both the component and spacecraft level. You will also be involved in exploring different thermal management strategies and demonstrating them through test campaigns. Our ideal candidate has experience with in-orbit integrated thermal analysis of spacecraft components using both first principles as well analytical models using software tools (such as Thermal Desktop, Ansys IcePak, and Python for automation purposes). Hands-on experience with thermal testing for spacecraft components such as thermal cycling and TVAC is highly preferred.

Responsibilities

Collaborate with Mechanical teams to develop passive and active thermal control hardware for the spacecraft including radiators, heaters, heat pipes, and surface coating

Partner with Avionics teams to develop thermal models and thermal tests for electronic assemblies

Work with the GNC teams to define and thermally analyze nominal and contingency cases for in-orbit operations of the spacecraft

Develop and maintain thermal models for spacecraft and sub-components using Thermal Desktop and Ansys

Interface with vendors and launcher providers to understand their design and translate it into thermal-related requirements

Automate data analysis to support architectural trades effectively

Set up and execute thermal testing ranging from development to qualification

Qualifications

8+ years of experience with satellite thermal design and analysis

Demonstrated experience with radiative and conductive thermal modeling of spacecraft systems using Thermal Desktop

Experience with selection, sizing, and design of thermal control hardware including heat pipes, heaters, stickers, OSR, thermal straps, thermal paints, tapes, MLI, TEC

Experience with thermal cycling and thermal vacuum testing including predictions, setup, instrumentation and thermal model correlation

Nice to Have

Experience with full-vehicle thermal vacuum testing and model correlation

Experience with spacecraft thermal design optimized for cost, reliability, performance and manufacturability

Experience with integrated thermal analysis of spacecraft and rocket

Experience with solar panel thermal modeling

Experience with electrical PCBA thermal modeling and thermal interface materials (thermal grease, gap pads, etc.)

Experience with spacecraft primary radiator design and analysis

Familiarity with SMC-S016 standard or equivalent

Experience with Python, C/C++, or Matlab for thermal modeling and automated data analysis

Compensation and Benefits:

Base salary range for this role is $175,000 - $295,000 + equity in the company

Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level

Comprehensive benefits package including paid time off, medical/dental/vision/ coverage, life insurance, paid parental leave, and many other perks
