The Opportunity:

CACI is seeking an Intermediate Modeling & Simulation (M&S) Engineer to support our critical defense programs at Aberdeen Proving Ground, MD.

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

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
