About The Position

L3Harris is seeking a senior software engineer to lead a ground station software component. The role leads development of mission-critical satellite ground systems software supporting command and control, telemetry processing, mission planning, automation, simulation, and operator tools. It combines hands-on software design, integration, testing, and performance optimization to deliver secure, reliable, and maintainable ground station capabilities for space missions and operational users. The position is located in Palm Bay, Florida, or Fort Wayne, Indiana, and follows a 9/80 schedule.

The engineer works across the full software lifecycle, designing, deploying, and sustaining software services in AWS cloud environments. The role uses infrastructure automation, containerized applications, cloud-native monitoring, modern engineering and DevSecOps practices, and AI-assisted engineering tools. AI-generated output must be validated for correctness, security, maintainability, and mission suitability before integration. The position also involves integration with simulators, hardware interfaces, external services, databases, and mission support systems; automated testing; architecture and interface support; troubleshooting; and requirements analysis. Travel is no more than 10%.

Requirements

• Bachelor’s degree and at least 6 years of relevant experience; or a graduate degree and at least 4 years of related experience; or at least 10 years of related experience in lieu of a degree.
