Senior Flight Software Engineer

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run. We are seeking a highly motivated Senior 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.

• 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.

• 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.
• Excellent cross-disciplinary communication and collaboration skills.
• Good understanding of math & physics.
• Focus on detail, quality, and testing.
• Experience with CI/CD systems and build systems.

• Agile working environment.
• Open and collaborative culture with transparency about risks and obstacles.
• Opportunity to work towards democratizing space.
• Relocation assistance and visa sponsorship where applicable.
