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.

• 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

• Execute testing across:
• Unit, module, and system levels
• Hardware‑in‑the‑Loop (HIL) / Flat Sat environments
• Develop test frameworks, tools, and ground support software
• Support debugging, validation, and anomaly resolution

• Contribute to modeling & simulation efforts
• Support new mission concepts and proposals
• Evaluate impacts of new hardware, architectures, and mission profiles

• 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

• Bachelor’s degree in a STEM field required
• Master’s degree preferred - 7 years of experience

• Up to ~20% travel (domestic)
• Occasional international collaboration

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.
