Principal Flight Software Engineer

Here at The Exploration Company, we are building innovative aerospace technologies that advance the future of space transportation. We are looking for an experienced and hands-on Principal Flight Software Engineer (Team Lead) to lead the development at one of the key teams working on the Flight Software stack for Nyx. In this critical role, you will guide a team of talented engineers in building and validating the software systems that control and operate the spacecraft: from launch to docking, re-entry, and recovery. You will combine deep technical expertise with strong leadership to deliver high-reliability software under tight mission timelines. You will collaborate with the other Flight Software teams and the Flight Software Lead to drive architectural decisions, enforce rigorous testing standards, and foster a culture of ownership, simulation-driven development, and cross-functional collaboration with other subsystems such as GNC, avionics, propulsion, and mission operations. This is a high-impact leadership position where your decisions directly influence mission success. KEY RESPONSIBILITIES

• Lead and mentor a high-performing team of flight software engineers in the design, implementation, testing, and integration of spacecraft software.
• Own the technical roadmap and execution for flight software, including architecture, modularity, and interfaces across avionics and vehicle subsystems.
• Set high standards for code quality, test coverage, simulation fidelity, and system robustness.
• Drive development in modern C++ (C++17 or newer) and Python, enabling safe and efficient spacecraft operations in real-time environments.
• Oversee the development of test infrastructure, including unit, integration, and hardware-in-the-loop (HIL) testing, to ensure flight readiness.
• Own key areas of the Nyx Flight Software, such as Simulation, Embedded software and firmware, specific subsystems… in accordance with your experience and expertise.
• Collaborate closely with teams across your team key stakeholders, for example systems engineering, GNC, propulsion, avionics, and mission operations to define requirements, resolve interface challenges, and validate end-to-end behavior.
• Participate in and lead code reviews, software audits, flight software simulations, and mission rehearsals. WHAT WE WOULD LOVE TO SEE FROM YOU
• Strong proficiency in modern C (Embedded/Firmware) or C++ (C++17 or newer, spacecraft software).
