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 and experienced Software System Engineer to support the certification activities of the flight software for the Nyx program. You will work in a dedicated team focused on verification & validation (V&V), software certification, requirements tracing, test planning and system engineering interfacing. In this role, you will collaborate closely with software development teams, system engineering, certification bodies, and safety authorities. You will work in a fast-paced, collaborative environment where cross-functional integration is essential.

Key Responsibilities

• Contribute to V&V and IV&V activities to ensure that flight software meets functional, performance, and safety requirements

• Support requirements management and tracing, ensuring full traceability from system-level requirements to software implementation, test and verification artifacts

• Prepare and review documentation required for software certification and NASA Safety Reviews

• Interpret, tailor, and apply formal standards

• Interface with internal Product Assurance

• Collaborate daily with system engineers and software development teams to resolve technical issues and clarify requirements

• Develop and maintain software functional design baseline

• Plan software testing of the integrated mission

• Use your understanding of C++ and Python to meaningfully engage in software design and test discussions

What we would love to see from you

• Experience working on safety-critical or highly regulated software systems (preferably in aerospace)

• Solid understanding of requirements management, V&V, test and certification processes

• Strong technical background in software engineering, with practical experience in flight software frameworks and modern C++

• Experience with real-time systems, embedded development, or spacecraft software

• Familiarity with software testing methodologies and simulation tools

• Excellent cross-disciplinary communication and collaboration skills

• Focus on detail, quality, and testing

• Familiarity with agile and modern development practices

Nice to have

• Familiarity with standards such as SSP 50808, NASA-NPR-7150.2, NASA-STD-8739.8B, RCC319, ECSS-Q-ST-80C

• Prior work on human-rated spaceflight programs

• Experience with model-based system engineering

• Experience with CI/CD systems and build systems
