About The Position

L3Harris Intelligence & Cyber Sector, within the Space and Mission Systems Segment, is seeking an experienced System Software Integration and Test Engineer to support complex cyber-resilient, cloud-based solutions across the full product lifecycle. The engineer will lead and support system integration and test activities, including requirements analysis for testability, test architecture development, integration planning, verification execution, anomaly resolution, and production support. The role develops and executes test plans, procedures, and integration flows for subsystems, lower-level assemblies, and end-to-end First Article testing. The position coordinates integration activities across test beds, hardware/software-in-the-loop environments, and software simulators developed internally and by subcontractors. It defines and implements verification strategies, supports requirements traceability and compliance, evaluates subsystem- and system-level performance, and collaborates with systems engineering, software engineering, quality, operations, and external partners to resolve technical issues and achieve system-level integration and verification objectives. The role supports secure software deployment and verification of software baselines, interfaces, and configuration changes. The position is based in Melbourne, Florida, and follows a 9/80 schedule: 80 hours over nine workdays in each 14-day period, with every other Friday off. Travel up to 10% may be required, along with extended and weekend hours during critical integration and test phases.
