Flight Software Engineer
About this role
Here at The Exploration Company, we are building spacecrafts for humanity. At The Exploration Company we are developing, producing, and operating Nyx - a modular, reusable orbital vehicle for space missions to stations and beyond. Nyx is engineered with the capability to transport cargo and, in the future, humans. We are seeking a highly motivated Flight Software Engineer to join our mission-driven team developing Nyx.
In this role, you will take full ownership of key components of the flight software stack. You will be designing, implementing, and testing mission-critical systems that enable safe, autonomous, and reliable spaceflight operations. You will work in a fast-paced, collaborative environment where cross-functional integration is essential. Your code will interface directly with vehicle avionics, guidance systems, propulsion, communications, and ground control.
Expect to write modern, high-reliability C++ and Python code, drive software simulations, and ensure flight readiness through rigorous testing at both unit and system levels. The position level will be determined based on your experience, technical depth, and ability to take ownership. Key Responsibilities Design, implement, and own core flight software modules for spacecraft control, telemetry, data handling, fault management, and communications.
Develop in modern C++ and Python for support tooling, following best practices in software architecture, testing, and performance optimization. Build and maintain test frameworks for automated unit, integration, and hardware-in-the-loop (HIL) testing to validate software behavior across mission phases. Create and run high-fidelity simulations to model flight dynamics, subsystem interactions, and edge cases. Collaborate closely with GNC, avionics, propulsion, and mission operations teams to ensure seamless integration and mission success.
Participate in code reviews, design reviews, and flight readiness assessments. What we would love to see from you Strong proficiency in modern C++ (C++17 or newer) and Python. Experience with real-time systems, embedded development, or spacecraft software. Demonstrated ability to take ownership of complex technical problems and drive them to resolution. Familiarity with software testing methodologies and simulation tools.
