The Role
Constellation's Flight Software team writes the code that actually flies the hardware. We are looking for a Flight Software Engineer to design and implement the highly reliable, real-time embedded systems that control our spacecraft and flight vehicles.
Responsibilities
Develop, test, and deploy mission-critical flight software in C/C++.
Implement guidance, navigation, and control (GNC) algorithms on embedded hardware.
Perform Hardware-in-the-Loop (HITL) testing to validate software under simulated flight conditions.
Collaborate with hardware engineers to define system architecture and interfaces.
Requirements
B.S. in Computer Science, Computer Engineering, Aerospace Engineering, or similar.
Exceptional programming skills in modern C and C++.
Extensive experience with Real-Time Operating Systems (RTOS) and embedded Linux.
Familiarity with hardware communication protocols (I2C, SPI, CAN, RS-422) and low-level debugging.

What We Do
Constellation Space builds ConstellationOS, an AI-native operating system that forecasts satellite link degradation minutes ahead and autonomously reroutes traffic under policy to prevent data loss. The platform ingests telemetry, uses physics-informed ML to predict failures with high accuracy, and executes rapid, policy-bound reroutes to provide mission assurance and scalable orchestration for large satellite constellations.
