This position is based onsite in the Dulles, VA or McLean/Tysons Corner, VA area and requires an active Top Secret clearance at the time of application.

Responsibilities

• Perform full stack software development across the operating system, platform, and mission-unique software layers for satellite ground systems.
• Design and develop client and server applications and services using service-oriented or object-oriented architectures and message bus–based data exchange.
• Implement applications using Python, C++, Postgres, Ansible, cloud infrastructure provisioning, PKI, and static code analysis tools, including remediation of findings.
• Act as a self-starter who makes sound technical decisions while considering overall project budget and schedule constraints.
• Support operations for ground software and associated configurations, including troubleshooting software errors and hardware issues that affect ground software performance.
• Configure ground segment software to meet mission and operational requirements.
• Support acceptance test events by planning, executing, and documenting tests.
• Develop and maintain test automation to improve reliability and efficiency of ground software validation.
• Identify, resolve, and remediate software defects in collaboration with the broader engineering team.
• Implement software enhancements driven by customer change requests and evolving mission needs.
• Provide ground software support during launch and launch rehearsal events to ensure mission readiness.
• Support the installation and deployment of new ground segment software in operational, development, and test environments.
• Collaborate with multidisciplinary teams working on spacecraft integration, mission assurance, and complex space-related challenges.

Essential Skills

• Bachelor’s degree in a STEM field, ideally Computer Science or Engineering, and at least 5 years of software engineering experience for Level 3; or a master’s degree and 3 years of experience; or a PhD. Experience may be considered in lieu of a degree with an additional 4 years of relevant work.
• Bachelor’s degree in a STEM field, ideally Computer Science or Engineering, and at least 8 years of software engineering experience for Level 4; or a master’s degree and 6 years of experience; or a PhD and 3 years. Experience may be considered in lieu of a degree with an additional 4 years of relevant work.
• Demonstrated professional software development experience on complex systems.
• Hands-on Python application development experience.
• Strong proficiency in C++ for production-grade software.
• Experience working with satellite ground software, ground systems, or spacecraft-related applications.
• Ability to develop applications using service-oriented or object-oriented architectures and message bus–based data exchange.
• Experience with full stack development, including operating system, platform, and mission-specific layers.
• Active Top Secret clearance at the time of application.

Additional Skills & Qualifications

• Experience with Postgres or similar relational database technologies.
• Experience with Ansible or similar tools for configuration management and infrastructure provisioning.
• Familiarity with cloud infrastructure provisioning and deployment practices.
• Knowledge of PKI and secure software development practices.
• Experience performing static code analysis and remediating identified issues.
• Experience or interest in UI/UX for mission or operations software interfaces.
• Exposure to MATLAB for data analysis or modeling in support of space missions.
• Experience working with satellite ground stations, spacecraft operations, or space-related systems.
• Strong preference for candidates holding Top Secret clearance with SCI eligibility or access.
• Intellectual curiosity and a desire to work on hardware and software that operate in space.
• Ability to thrive in a multidisciplinary engineering environment tackling complex problems such as radiation effects, autonomy, orbital mechanics, systems integration, and mission assurance.

Work Environment

This role is based onsite in a high-performance engineering environment in either Dulles, VA or the McLean/Tysons Corner, VA area. You will contribute to the build, integration, test, and operation of spacecraft and satellite ground systems that must function reliably in the harsh conditions of space.
