Software Engineer (Thermal & Fluid Analysis)

Starbase, TX

Full Time On-site

Summary

Job Description

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:
• Familiarity with thermal or fluid systems in spacecraft or aerospace applications
• Strong background in Python and data processing
• Experience automating engineering workflows or simulations
• Knowledge of and/or experience in MATLAB, C/C++, Git, Thermal Desktop, ANSYS Workbench, Siemens STAR-CCM+
• Understanding of thermal/fluid networks (0-D or 1-D modeling)
• Excellent communication and documentation skills
• Interest in making engineering tools easier to use and more scalable
• Familiarity with high performance computing

ADDITIONAL REQUIREMENTS:

Must be willing to work extended hours and/or 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. Section 1157, or (iv) Asylee under 8 U.S.C. Section 1158, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.

About 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.
