Flight Software Engineer

The Flight Software Engineer plays a key role in the full software development lifecycle for satellite and lander aerospace programs. This role focuses on designing, developing, and integrating C++ software for simulation, ground, and flight systems, ensuring reliable performance in demanding aerospace environments. You will collaborate closely with multidisciplinary engineering teams to integrate software with hardware and support mission-critical operations.

• Design, develop, and maintain flight software for satellite and lander aerospace programs across the full software development lifecycle.
• Develop C++ software for simulation, ground systems, and flight systems, ensuring high performance, reliability, and maintainability.
• Use NASA Trick and other simulation software tools to build, validate, and refine simulation models that support flight and ground operations.
• Collaborate with hardware, systems, and other engineering disciplines to integrate software into embedded hardware platforms.
• Implement, test, and debug embedded software in a Linux environment, ensuring compatibility with mission requirements and system constraints.
• Participate in code reviews, integration testing, and system-level validation to ensure software quality and adherence to engineering standards.
• Troubleshoot and resolve software issues in simulation, ground, and flight environments, providing technical support as needed.
• Contribute to documentation of software design, interfaces, and test procedures to support ongoing development and future maintenance.

• At least 2 years of flight software experience in aerospace or closely related environments.
• Strong proficiency in C++ for embedded, simulation, ground, or flight software development.
• Hands-on experience with flight software, ground software, or simulation software in operational or test environments.
• Experience working with simulation software tools such as NASA Trick or similar platforms.
• Proficiency in Linux for software development, deployment, and debugging.
• Bachelors degree in software engineering, computer science, or a closely related technical discipline.
• Solid understanding of embedded software development principles, including real-time constraints and hardwaresoftware integration.
• Demonstrated ability to participate in the full software development lifecycle, from requirements through design, implementation, testing, and integration.

• Experience with additional C or C/C++ development in embedded or systems-level contexts.
• Background in aerospace, satellite, or lander programs, or other mission-critical systems.
• Familiarity with ground systems software and tools used to support flight operations and mission control.
• Understanding of simulation methodologies and model-based development for complex systems.
• Ability to work effectively in a multidisciplinary engineering environment and communicate clearly with hardware and systems teams.
• Strong problem-solving skills with a focus on debugging complex software and integration issues.
• Attention to detail and commitment to producing reliable, well-tested software for high-consequence applications.

This position is based onsite in a collaborative aerospace engineering environment, working closely with teams developing satellite and lander programs. You will use Linux-based development systems, C++ toolchains, and simulation platforms such as NASA Trick to build and test flight and ground software. The work setting emphasizes teamwork, technical excellence, and rigorous testing to support mission success, with regular interaction across software, hardware, and systems engineering disciplines.
