About The Position

L3Harris Space Systems Sector, within the Space and Mission Systems Segment, is seeking an experienced SI&T / SW I&T Sr. Specialist to support spacecraft integration and verification activities at our Palm Bay, FL site. This is an on-site role supporting the integration, verification, and validation of complex space systems. The selected candidate will lead and support system integration and test activities across the full product lifecycle, including requirements analysis for testability, test architecture development, integration planning, verification execution, anomaly resolution, and production support. This role is responsible for developing and executing test plans, procedures, and integration flows for spacecraft RF subsystems, lower-level assemblies, payload interfaces, and end-to-end Space Segment testing. Responsibilities also include coordinating integration activities for test beds, hardware/software-in-the-loop environments, and software simulators developed internally and by subcontractors. The Sr. Specialist will define and implement verification strategies, support requirements traceability and compliance, evaluate subsystem and system-level performance, and work cross-functionally to resolve technical issues discovered during integration and test. This position requires close collaboration with systems engineering, software engineering, mission, payload, quality, and operations teams, as well as external partners, to ensure technical readiness and successful execution of system-level integration and verification objectives. The ideal candidate will bring strong experience in complex system integration, spacecraft or aerospace test environments, and execution of structured verification and validation processes.
