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.
🚀 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.
