The primary focus of this position is the modeling, simulation, and software-level representation of terrestrial RF signals and systems. This includes ground-based radar systems, tactical communication networks, terrestrial jammers, and electromagnetic environmental effects. You will analyze intelligence-derived parametric data and design high-fidelity emitter and signal simulations to support hardware-in-the-loop (HWIL) and software-in-the-loop (SWIL) testing. **Responsibilities:** · Terrestrial EW Signal Representation: Interpret parametric data, technical intelligence (TECHINT), and design documents to model ground-based RF emitters, tactical communications, and electronic attack (jamming) systems. · Algorithm & Simulation Development: Create, test, and integrate algorithms that simulate complex terrestrial signals, including frequency-hopping spread spectrum (FHSS), direct-sequence spread spectrum (DSSS), and various analog/digital modulation schemes. · RF Environment Modeling: Develop and configure simulation environments that account for terrestrial RF propagation factors such as terrain masking, multipath interference, atmospheric loss, and foliage penetration. · System Logic & Behavior Modeling: Understand how threat systems operate and translate their operational logic, antenna patterns, and scan behaviors into functional software models. · System Testing & Validation: Support the integration of threat models into simulated environments to test tactical EW software, evaluating how system-level characteristics affect signal emission and reception. **Qualifications:** *Required:* · Citizenship & Clearance: US Citizenship is required. Must be able to obtain and maintain a DoD Secret security clearance (Active Secret Clearance preferred). · Experience: 2+ years of professional experience in an engineering, modeling, or software development role. · Education: Bachelor’s degree in a STEM field (Electrical Engineering, Physics, Mathematics, Computer Science, or a closely related discipline). · Software Fundamentals: Strong command of general programming fundamentals, including:    · Variables, functions, Booleans, arrays, and array manipulation.    · Algorithm design (translating physical inputs and mathematical logic into distinct outputs).    · Object-Oriented Programming (OOP) concepts. · Technical Adaptability: Proven ability to analyze physical systems (RF, mechanical, or logical) and represent them mathematically or programmatically. · Office Tools: Comfortable using standard Windows-based productivity tools (Office Suite, Visio, etc.). *Desired:*  EW & RF Principles: Sound knowledge of basic Electronic Warfare concepts (EA, EP, ES) and RF propagation principles. · RF Propagation Modeling: Familiarity with terrestrial propagation models (e.g., Longley-Rice / ITM, TIREM, or APM). · Technical Tools & Languages:    · Experience with scientific programming languages such as MATLAB, Python, or C++ for signal processing or modeling.    · Experience with Software Defined Radios (SDRs) and signal analysis frameworks (e.g., GNU Radio).    · Familiarity with version control systems, specifically Git/GitLab. · Laboratory Hardware: Basic experience or familiarity with RF test equipment and hardware analysis tools (Spectrum Analyzers, Signal Generators, Oscilloscopes, Network Analyzers) and standard hardware connectivity protocols   \- **What You Can Expect:** **A culture of integrity.** At CACI, we place character and innovation at the center of everything we do. As a valued team member, you’ll be part of a high-performing group dedicated to our customer’s missions and driven by a higher purpose – to ensure the safety of our nation. **An environment of trust.** CACI values the unique contributions that every employee brings to our company and our customers - every day.
