Senior Flight Software Engineer

At Turion Space, we’re building spacecraft to secure Earth and expand humanity’s reach beyond it. Our missions span national security, in-space servicing, and orbital debris removal and flight software is the heartbeat of everything we launch.

We’re looking for a Senior Flight Software Engineer to design, build, and test embedded systems that directly control spacecraft behavior and performance. You’ll work cross-functionally across hardware, systems, and mission ops to develop software that’s robust, real-time, and ready for space.

Prior aerospace experience isn’t required. We’re looking for passionate software engineers who want to solve hard problems and make an impact.

• Own the full lifecycle of spacecraft flight software—from early architecture through development, test, and on-orbit operations.

• Lead technical design and implementation of high-reliability embedded systems for spacecraft command and control, autonomy, and fault tolerance.

• Develop simulation environments, test harnesses, and HIL setups to validate software in mission-representative conditions.

• Drive root-cause analysis and troubleshooting efforts for system-level software and hardware interactions across development and flight.

• Collaborate closely with hardware, systems, avionics, and mission ops teams to ensure end-to-end integration and performance.

• Author and maintain critical documentation including software architecture docs, ICDs, verification plans, and test results.

• Influence and improve team-wide software development practices, tooling, and design patterns.

• Mentor junior engineers and help shape the flight software team’s culture, technical standards, and review processes.

• 5 Years of experience in embedded software development, including full lifecycle ownership from design to test and deployment

• Strong proficiency in C/C++ in a Linux or embedded environment

• Demonstrated experience writing high-reliability software that interfaces with hardware in real-time systems

• Proven ability to lead projects or technical domains independently, with minimal oversight

• The ability to obtain and maintain an active DOD Secret or Top Secret security clearance

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field

• 7 years of experience developing embedded software for spacecraft, aerospace systems, robotics, or autonomous vehicles

• Deep familiarity with:

  • Embedded Linux (e.g. Yocto, Buildroot), RTOS, file systems, and bootloaders

  • Spacecraft protocols and standards: CCSDS, CAN, SPI, Ethernet/IP

  • Software frameworks like NASA cFS, F Prime (F’), or similar architectures

  • CI/CD tools and version control systems (e.g. Git, Jenkins)

  • Simulation, test automation, and HIL environments (GTest, PyTest, custom frameworks)

• Experience in fault-tolerant architectures, real-time state machines, or autonomous control logic

• Prior technical leadership or mentorship experience

• An active DOD Secret or Top Secret Clearance

Additional Requirements:

• A passion for building in small, fast-moving teams

• Willingness to work extended hours or weekends to meet mission-critical deadlines
