Senior/Principal Software Engineer

🚀 Senior / Principal Flight Software Engineer – Space Systems

*REMOTE*

Working with a leading U.S. aerospace company looking to add Senior and Principal-level Flight Software Engineers to their satellite team.

This is a hands-on role focused on building and testing embedded flight software for spacecraft, with exposure across the full mission lifecycle. from early concept through on-orbit operations.

What you’ll be doing:

• Develop and test embedded C/C++ flight software for satellite platforms


• Contribute across the full lifecycle:


• Requirements definition & trade studies


• Software architecture & development


• Integration with flight hardware


• Verification, validation, and operations


• Support GNC-related software integration and system performance analysis


• Build internal tools to evaluate flight software performance and mission compatibility


• Work closely with hardware, systems, and test teams in a highly collaborative environment

Testing & Integration:

• Execute testing across:


• Unit, module, and system levels


• Hardware-in-the-Loop (HIL) / FlatSat environments


• Develop test frameworks, tools, and ground support software


• Support debugging, validation, and anomaly resolution

Additional exposure:

• Contribute to modeling & simulation efforts


• Support new mission concepts and proposals


• Evaluate impacts of new hardware, architectures, and mission profiles

What they’re looking for:

• 9–15+ years of experience in software engineering (level dependent)


• Strong background in embedded software development (C/C++)


• Experience with flight software, avionics, or aerospace systems


• Hands-on experience with hardware/software integration and testing


• Exposure to one or more of the following:


• GNC algorithms


• RTOS (VxWorks, Integrity, etc.)


• Device drivers / BSP / bring-up


• HIL / simulation environments


• Software verification & validation


• Ability to operate as a high-level IC across multiple domains

Education:

• Bachelor’s degree in a STEM field required


• Master’s degree preferred - 7 years of experience
  

Travel:

• Up to ~20% travel (domestic)


• Occasional international collaboration

Quick take:

This is a high-impact IC role for engineers who want to stay deeply technical while working on cutting-edge spacecraft and flight software systems.
