Senior Specialist, Systems Engineering

Job Code: 46188 Job Location: Palm Bay, FL Job Schedule: 9/80 Job Description: L3Harris is seeking a Systems Engineer to support the development, launch, checkout, and on-orbit operation of advanced satellite and space mission systems. This role will focus on mission and system requirements, launch readiness support, operational performance assessment, telemetry and data analysis, and anomaly investigation/resolution across the mission lifecycle.

Essential Functions: Develop, analyze, and manage system and subsystem requirements for satellite, payload, and mission operations systems. Support mission planning, launch preparation, readiness activities, and transition from integration and test into operational use. Analyze spacecraft and ground system telemetry, trends, and performance data to assess system health, operational status, and mission effectiveness. Lead or support technical investigations of on-orbit, launch-phase, or ground-system anomalies, including fault isolation, root cause analysis, and corrective action development. Define and maintain requirements traceability from mission objectives through system, subsystem, and operational products. Collaborate with flight operations, software, hardware, integration and test, and ground system teams to refine interfaces, operational concepts, and technical baselines. Support development of CONOPS, operational procedures, system architectures, interface definitions, and verification strategies. Participate in launch campaign activities, operational rehearsals, readiness reviews, design reviews, and anomaly review boards. Assess engineering changes and operational impacts to mission performance, reliability, cost, and schedule. Support verification and validation planning to ensure requirements and operational constraints are measurable and testable. Contribute to risk management, issue tracking, and technical decision-making throughout launch, commissioning, and mission operations. Prepare and maintain technical documentation, status briefings, and analysis products for internal and customer stakeholders.

Qualifications: Bachelor's Degree with a minimum of 6 years prior relevant experience. Graduate Degree with a minimum of 4 years of prior related experience. In lieu of a degree, minimum of 10 years prior related experience. Experience supporting spacecraft, payload, ground, or mission operations for space systems programs. Experience in requirements development, decomposition, verification planning, and traceability. Experience analyzing telemetry, mission data, or operational performance data to support decision-making and issue resolution. Experience with anomaly investigation, troubleshooting, and root cause analysis in a complex technical environment. Active security clearance.

Preferred: Additional Skills: Experience supporting satellite launch campaigns, early orbit operations, commissioning, or sustained on-orbit mission operations. Experience with space vehicle telemetry analysis, fault management, command and control workflows, and spacecraft health monitoring. Experience with requirements management tools such as DOORS, DOORS Next, Jama, or similar platforms. Experience with Model-Based Systems Engineering (MBSE) approaches and tools such as Cameo, MagicDraw, Rhapsody, or SysML-based modeling. Experience with mission operations products such as operational procedures, command plans, limit sets, trending tools, and anomaly response processes. Experience with systems engineering lifecycle activities spanning concept development, integration and test, launch, operations, sustainment, and disposal. Experience supporting defense, national security space, civil space, or commercial space programs.#LI-KB1
