Digital Signal Processing Engineer

Digital Signal Processing Engineer – CACI International Inc

Join CACI International Inc as a (entry‑level) Digital Signal Processing (DSP) Engineer to support the development of next‑generation signals intelligence (SIGINT) and electronic warfare technologies for the counter‑unmanned aircraft systems (C‑UAS) mission.

Engineering – Full time – Regular – No travel required.

• Independently develop, integrate, test, and debug well‑defined signal processing algorithms and software components supporting SIGINT and electronic warfare systems.
• Implement and evaluate DSP algorithms and analytic signal processing tools, owning discrete tasks from initial implementation through validation and testing.
• Contribute to the development and application of machine learning techniques for signal analysis, detection, classification.
• Enhance and maintain existing Government Off‑The‑Shelf (GOTS) signal processing tools, such as X‑Midas and M2
  
  Extra, while learning domain‑specific frameworks and workflows.
• Collaborate with senior engineers to translate requirements and CONOPs into implementable software solutions, contributing technical analysis and documentation.
• Use computer‑aided engineering and software tools to independently analyze, test, debug, and validate signal processing solutions.
• Work closely with cross‑functional teams in an environment that values initiative, technical curiosity, and continuous learning.

• Expected graduation in Spring 2026 with a Bachelor’s degree in Electrical Engineering, Computer Engineering, Applied Mathematics, Computer Science, or a related field.
• Hands‑on experience applying signal processing concepts through coursework, internships, research, labs, or capstone projects.
• Programming experience in Python and/or C++, gained through academic, internship, or project work.
• Familiarity with Linux‑based software development environments.
• Demonstrated ability to work independently on technical assignments, manage time effectively, and deliver results with limited day‑to‑day direction.
• Ability to clearly communicate technical and analytical information in written and verbal form.
• Exposure to the software development lifecycle (concept, design, implementation, test, and integration).
• Experience working on collaborative, team‑based technical projects.
• Ability to obtain and maintain a TS/SCI clearance.

• Master’s degree (or progress toward one) in a relevant technical discipline.
• Coursework or project experience in communications systems, RF engineering, or DSP.
• Exposure to software‑defined radio (SDR) concepts, including
  • Receiver architectures, Modulation and demodulation techniques, Spectral analysis or channelization
• Experience performing link budgets, range estimates, or system sensitivity analysis through academic or project work.
• Familiarity with X‑Midas, GNU Radio, MATLAB, or similar signal processing tools.
• Introductory experience with containerization tools such as Docker or Kubernetes.
• Coursework or project experience involving
  • Machine learning or data analytics, Error‑correcting codes, Digital video formats or telemetry systems, Target tracking or estimation techniques
