Senior Systems Engineer

Leidos' Defense Sensors is seeking a Senior Systems Engineer to join its team in Lawton, Oklahoma, and Huntsville, Alabama, developing state-of-the-art Counter Unmanned Aircraft Systems (C-UAS) and Mobile Short-Range Air Defense (M-SHORAD) aligned solutions.

The Senior Systems Engineer will 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.

Key responsibilities include:

• Applying 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.
• Developing, maintaining, and refining system models in Cameo Systems Modeler to support requirements decomposition, traceability, interface definition, architecture development, and verification planning.
• Analyzing, defining, and managing operational, functional, interface, and performance requirements for CUAS command and control systems, integrated sensors, effectors, and communications architectures.
• Maintaining 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.
• Supporting integration of sensors, effectors, communications, networking, and C2 software into cohesive CUAS solutions that meet mission objectives and interoperability requirements.
• Planning, coordinating, and executing systems integration and test activities at the subsystem, system, and system-of-systems levels.
• Performing C2 software testing, including functional, interface, regression, performance, and operational testing in laboratory, integration, and field environments.
• Troubleshooting hardware, software, network, and interface issues identified during integration and test, and supporting timely resolution of discrepancies and defects.
• Supporting test planning, procedure development, execution, data analysis, and reporting for developmental and operational test events.
• Conducting technical reviews, trade studies, engineering analyses, and risk assessments to support design decisions, capability maturation, and program milestones.
• Ensuring compliance with applicable program, quality, safety, cybersecurity, and Department of Defense engineering and test standards.
• Providing technical leadership across cross-functional engineering, integration, and test teams, and mentoring junior engineers as needed.
• Supporting configuration management, software release management, and documentation of integrated CUAS system baselines.
• Participating in customer and stakeholder meetings, providing technical briefings, engineering recommendations, and status on system performance and test progress.
• Contributing to transition-to-production and transition-to-fielding activities, including readiness assessments and support to operational users.

The successful candidate will have a Bachelor's degree in Systems Engineering, Software Engineering, Computer Science, Computer Engineering, Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or an equivalent degree from an ABET-accredited university with 12+ years of experience, or an MS with 10+ years.

Preferred qualifications include experience with Cameo and/or other Model-Based System Engineering (MBSE) modeling tools, demonstrated experience effectively leading a team of engineers, and INCOSE Systems Engineering Professional (SEP) certification.

Leidos offers a salary range of $131,300.00 - $237,350.00.
