Job Description
Software Engineer (Thermal & Fluid Analysis) SpaceX United States, Texas, Brownsville 1 Rocket Road (Show on map) May 22, 2026 SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal ofenabling human life on Mars.
SOFTWARE ENGINEER
(THERMAL & FLUIDANALYSIS
) The Thermal & Fluid Analysis team supports the design and testing of Starship's thermal and fluids systems. These include active and passive thermal control, propellant feed systems, gas systems, thermal protection, and in-space propellant management among many other subsystems. These systems must perform reliably in extreme environments from launch to recovery. In this role, you will develop software tools to support analysis, improve design processes, automate workflows, and subsequently deploy the new software/workflows to the analysis and engineering community. Your work will enable making informed decisions more quickly and thus reducing the time required to realize a self-sustaining colony on Mars. This role requires strong software development skills and an interest in simulation, thermal design, and fluid systems. Experience with thermal & fluid system modeling technique and simulation is a major plus.RESPONSIBILITIES
- Design software and workflows that improve mission critical analysis throughput
- Build infrastructure to support thermal and fluid systems analysis
- Automate analysis workflows to speed up mission and design iteration
- Support simulation and validation with test and flight data
- Collaborate with engineers to improve reliability and performance of spacecraft systems
- Write clean, scalable code and maintain strong documentation
BASIC QUALIFICATIONS
- Bachelor's degree in computer science, engineering, physics, mathematics, or a related field
- 1+ years of experience coding in Python, JavaScript, and/or Rust (including internship or academic experience)
PREFERRED SKILLS AND EXPERIENCE
