Primary Responsibilities

Lead systems engineering activities across the full Counter-Unmanned Aircraft Systems lifecycle, including requirements analysis, architecture development, design integration, verification, validation, and transition to fielding.
Apply Model-Based Systems Engineering (MBSE) methods to define, analyze, and manage system requirements, behaviors, interfaces, and architectural relationships for CUAS solutions using digital engineering best practices.
Develop, maintain, and refine system models in Cameo Systems Modeler to support requirements decomposition, traceability, interface definition, architecture development, and verification planning.
Analyze, define, and manage operational, functional, interface, and performance requirements for CUAS command and control systems, integrated sensors, effectors, and communications architectures.
Maintain end-to-end requirements traceability from mission needs through design, integration, and test, including verification mapping and technical baseline control in model-based and document-based artifacts.
Support integration of sensors, effectors, communications, networking, and C2 software into cohesive CUAS solutions that meet mission objectives and interoperability requirements.
Plan, coordinate, and execute systems integration and test activities at the subsystem, system, and system-of-systems levels.
Perform C2 software testing, including functional, interface, regression, performance, and operational testing in laboratory, integration, and field environments.
Troubleshoot hardware, software, network, and interface issues identified during integration and test and support timely resolution of discrepancies and defects.
Support test planning, procedure development, execution, data analysis, and reporting for developmental and operational test events.
Conduct technical reviews, trade studies, engineering analyses, and risk assessments to support design decisions, capability maturation, and program milestones.
Ensure compliance with applicable program, quality, safety, cybersecurity, and Department of Defense engineering and test standards.
Provide technical leadership across cross-functional engineering, integration, and test teams and mentor junior engineers as needed.
Support configuration management, software release management, and documentation of integrated CUAS system baselines.
Participate in customer and stakeholder meetings, providing technical briefings, engineering recommendations, and status on system performance and test progress.
Contribute to transition-to-production and transition-to-fielding activities, including readiness assessments and support to operational users.
Leverage INCOSE systems engineering principles and practices in execution of requirements management, architecture development, integration, and verification activities; INCOSE CSEP certification is desired or preferred for candidates in this role. Leidos resources identify CSEP as the certification level recognizing systems engineering practitioners with demonstrated knowledge and experience, and note that it requires 5 years of systems engineering experience.

Position requires candidates to be capable of performing in a collaborative engineering environment working closely with multi-disciplinary teams.
Demonstrated experience effectively communicating within a team environment.
Resident of the North Alabama area or willing to relocate to the Huntsville - North Alabama, AL area.
Must be a US citizen, possess a secret clearance, or have the ability to obtain a secret clearance.
