At SpaceX, we are applying our expertise in building rockets and spacecraft to create the world's largest and most advanced satellite broadband system. Starlink delivers fast, reliable internet to millions of users through a vertically integrated network of satellites, receiver antennas, lasers, gateways, and sophisticated software. We design, build, test, and operate every part of the system to serve users everywhere on Earth.

As a thermal engineer, you are responsible for the thermal design, test, and validation of all Starlink hardware. This includes but is not limited to phased array antennas, custom silicon design for chips, consumer WiFi, and other RF systems to be developed in the future. You will use your skills in thermal analysis to make engineering decisions that improve the performance of Starlink hardware everywhere from remote research labs in Antarctica to Mach 0.7 in-flight.

RESPONSIBILITIES:

  • Thermal system design of next-generation phased arrays, gateways, and consumer wireless products - own every component, part, and interface in the design
  • Thermal design of semiconductor packages, from high level concepts to detail thermal simulations and lab testing
  • Devise, build, and run tests to validate the expected performance of the hardware in extreme conditions
  • Automate workflow and pursue operational simplicity to reduce engineering investment in the design cycle
  • Utilize first-principles approach to evaluate sizing cases and impact of design decisions
  • Perform analysis to make recommendations for performance/robustness improvements
  • Produce quality documentation of your work for design requirements and specifications
  • Continuous collaboration with mechanical, electrical, software, and RF design teams

BASIC QUALIFICATIONS:

  • Bachelor's degree in engineering discipline
  • 1+ years of experience with mechanical design, electromechanical design, and/or analysis (internship or project team experience is applicable)

PREFERRED SKILLS AND EXPERIENCE:

  • Master's degree in relevant engineering discipline
  • 1+ years of experience using scientific programming languages such as MATLAB, Python
  • Experience with Thermal Desktop and ANSYS Workbench
  • Experience with tools for chip thermal design like Flotherm or Icepak
  • Experience with 3D and reduced order thermal modeling
  • Excellent oral and written communication skills
  • Ability to deliver against an aggressive schedule

ADDITIONAL REQUIREMENTS:

  • Must be available to work extended hours and weekends as needed

ITAR REQUIREMENTS:

  • To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C.

About SpaceX

SpaceX

SpaceX is one of the most influential aerospace companies in the world, transforming space launch, satellite communications, and deep-space transportation. Founded by Elon Musk, SpaceX designs and manufactures advanced rockets and spacecraft, including Falcon 9, Falcon Heavy, and Starship, alongside the Dragon spacecraft and the Starlink satellite internet constellation. The company plays a major role in U.S. space access, national security launch capabilities, and commercial space infrastructure.

For job seekers, SpaceX offers opportunities across some of the most demanding engineering disciplines in the industry, including aerospace engineering, propulsion, software development, avionics, manufacturing, robotics, materials science, and mission operations. The company is especially attractive to engineers, technicians, and builders who want to work in a high-intensity environment focused on rapid iteration, vertical integration, and hands-on hardware development at scale.

Unlike traditional aerospace contractors that rely heavily on long development cycles, SpaceX operates with a fast-paced, vertically integrated engineering culture where teams design, build, test, and fly systems in rapid succession. Employees often work directly on flight hardware and production systems, contributing to programs that routinely push the boundaries of reusability, launch frequency, and cost reduction in space access.

As global demand for satellite communications, space infrastructure, and national security launch services continues to grow, SpaceX remains one of the most important employers in aerospace and defense-adjacent technology. For professionals seeking a highly challenging, mission-driven career at the cutting edge of spaceflight and advanced engineering, SpaceX stands out as one of the most ambitious and impactful companies in the world.
