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 Software Engineer to join our mission-driven team developing Nyx. In this role, you will take full ownership of key components of the mission tooling software stack. You will be designing, implementing, and testing mission-support systems that enable safe, autonomous, and reliable spaceflight operations, such as tools related to deployment, configuration data management, autocoding, and simulation.
You will work in a fast-paced, collaborative environment where cross-functional integration is essential. Your products will be used by flight software engineers, GNC engineers, system and mission operations engineers, and ground software teams. Expect to write robust and well-tested Python code, interface directly with users across the technical departments, and take ownership for tools you develop.

• Design, implement, and own core software tools for mission-related automation, testing, simulation, deployment, and configuration data management.
• Listen to user needs across engineering and software departments.
• Develop in modern Python, following best practices in software architecture, testing, and performance optimization.
• Interface with C++ flight software, ground software, system engineering tools, and maintain related CI/CD configurations.
• Build and maintain test orchestration and simulation management tools to validate software behavior across mission phases.
• Collaborate closely with GNC, avionics, system engineering, and mission operations teams to ensure efficient and user-driven tool design.
• Participate in code reviews, design reviews, and flight readiness assessments.
