We are seeking an experienced System Engineer with deep expertise in Electronic Warfare (EW) mission systems to lead in developing technical requirements and system architectures for CACI product development supporting critical US Government and foreign military programs. This role demands a unique blend of software-centric systems engineering, operational EW domain knowledge, and the ability to decompose complex system requirements across multidisciplinary teams

Key Responsibilities

Requirements Development & Management

• Establish and maintain system baselines including functional, performance, and interface requirements
• Lead requirements definition through evaluation of customer high-level system requirements and capability need statements with customer and engineering team technical interactions.
• Manage requirements traceability from mission needs through verification and validation
• Coordinate solutions across multiple physical locations and organizations.

EW Mission Systems Engineering

• Apply deep understanding of EW operational concepts, tactics, techniques, and procedures (TTPs) to translate mission needs into technical requirements
• Define system behavior for EW functions including threat detection, identification, geolocation, jamming, and countermeasures
• Support development of Concepts of Operations (CONOPS) and mission thread analysis for EW systems
• Collaborate with internal and external stakeholders to refine requirements

Technical Architecture & Decomposition

• Develop and document system and software architectures that meet EW mission requirements and operational constraints
• Decompose functional requirements to software, hardware, RF, signal processing, and other engineering disciplines
• Define and document interfaces and data flows between subsystems
• Lead Functional and Physical Architecture development and allocation

Cross-Functional Technical Leadership

• Serve as primary technical interface between system-level engineering and specialized engineering teams
• Facilitate requirements understanding across software engineering, signal processing, RF engineering, hardware engineering, and integration and operational teams
• Conduct technical reviews and ensure subsystem designs satisfy allocated requirements
• Identify and resolve requirements conflicts and technical risks across disciplines

Required Qualifications

Technical Skills

• Software-Centric Systems Engineering: Strong background in software architecture, software requirements specification, and software-intensive system design
• Software Development Lifecycle: Understanding of Agile, DevSecOps, and CI/CD practices in DoD environments

EW Domain Expertise

• 5+ years of experience in EW systems development, integration, or operations, or equivalent system complexity.
• Understanding of EW operational disciplines with working knowledge of how mission requirements translate to system capabilities
• Knowledge of RF propagation, antenna systems, receiver/transmitter architectures, and signal processing
• Understanding of test and evaluation methodologies applied to EW systems

Systems Engineering Fundamentals

• 7+ years of systems engineering experience with at least 3 years in requirements development
• Demonstrated ability to decompose system requirements to software, hardware, and firmware subsystems
• Experience with verification and validation planning and execution
• Experience documenting and maintaining system engineering artifacts including:
• System architecture descriptions and diagrams
• Interface control documents (ICDs)
• Requirements specifications and traceability matrices
• Data flow and sequence diagrams
• Trade study and technical analysis experience

Clearance & Education

• BS in Systems Engineering, Software Engineering, Electrical Engineering, Computer Science, or related technical field
• US Citizenship and ability to obtain TS/SCI clearance

Desired Qualifications

• Active TS/SCI security clearance preferred
• INCOSE CSEP or ESEP certification
• Familiarity with open systems architecture standards (CMOSS, SOSA, FACE)
• Understanding of software testing frameworks and automated test development
• Familiarity with formal requirements and design reviews (SRR, PDR, CDR, TRR, etc.)

Work Environment

• Hybrid/On-site position supporting Florham Park, NJ or Westminster, CO
• Travel to other CACI locations and/or customer sites as necessary (travel requirement is typically 0 - 15%)
• Fast-paced, collaborative engineering environment
