Software Development Test Engineer (Starlink)

About the role

At SpaceX, we are leveraging our experience in building rockets and spacecraft to deploy Starlink, the world's most advanced broadband internet system. Starlink is the world's largest satellite constellation, providing fast, reliable internet to millions of users worldwide. Our mission is to design, build, test, and operate all parts of the system, including thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that integrates it all.

As a Software Development Test Engineer for Starlink, you will be responsible for designing and building “hardware-in-the-loop” (HIL/HITL) test systems. These systems allow for Starlink software engineers to build technologies such as space laser mesh networks, next-generation phased array antennas, advanced collision avoidance algorithms, and much more.

Responsibilities

• Design, build, and maintain highly reliable hardware-in-the-loop (HIL/HITL) testbeds—including surrounding infrastructure, tooling, and support equipment—for the Starlink software continuous integration system
• Develop test cases and create simulation environments that replicate on-orbit scenarios to deliver flight-like testing capabilities
• Ensure all software has an appropriate level of test coverage, balancing reliability, velocity and safety
• Pioneer innovative strategies to scale the HITL fleet in accordance with the Starlink software organization’s growing test demands
• Analyze and troubleshoot HITL test results to identify testbed issues and prevent software bugs from reaching production

Qualifications

Bachelor’s degree in software, electrical, mechanical, aerospace, or a related engineering discipline

1+ years of professional test experience within electrical, mechanical, and/or aerospace engineering

Development experience in Python

Skills

• Experience with integration and testing of electrical, electromechanical, RF, and/or high voltage systems
• Experience with electrical test equipment such as oscilloscopes, DAQs, electronic loads, and spectrum analyzers
• Experience with 3D CAD software for design, modeling, and manufacturing applications
• Experience with programmable logic controllers (PLCs)
• Experience with communication protocols including USB, VISA, CAN bus, SPI, I2C, and Modbus
• Experience working with networking hardware and troubleshooting layers 2-4 of the OSI-model
• Strong skills in troubleshooting, debugging, performance optimization, and unit testing
• Solid fundamental knowledge of networks, electronics, RF communications, math, and physics
• Experience with simulation software and data analysis
• Excellent organizational and communication skills
• Ability to learn quickly and work effectively in a dynamic environment
