CACI is currently looking for a Senior Digital Signals Processing Engineer to join our team developing next generation signals intelligence (SIGINT) for the U.S. Army. Join this passionate team of industry-leading individuals on a program that leverages the best practices developing DSP algorithms for real-time or near-real-time systems to deliver state-of-the-art capability in support of our nation’s warfighters. As a member of the CACI Team, you will support the men and women charged with safeguarding the American people and enhancing the Nation’s safety, security, and prosperity.

• Lead technical development on a new project for the customer.
• Serve as the DSP subject matter expert for RF measurement and mapping activities.
• Develop and deploy algorithms that estimate Effective Isotropic Radiated Power (EIRP) within defined accuracy requirements.
• Process large-scale RF measurement datasets and generate geospatial EIRP coverage products.
• Lead technical investigations of measurement discrepancies and propagation anomalies.
• Hybrid schedule available.

• Bachelor’s degree in electrical engineering, Computer Engineering, Physics, Mathematics, or related field.
• 8+ years of experience in Digital Signal Processing, RF systems, or wireless communications.
• U.S. citizenship.
• TS/SCI Clearance with CI Poly.
• Strong programming skills in C/C++, Python, MATLAB/Simulink.
• Experience developing DSP algorithms for real-time or near-real-time systems.
• Radio Frequency (RF) and Communications Expertise.
• Effective Isotropic Radiated Power (EIRP) Measurement Experience.

• Strong understanding of RF propagation, antenna theory, EIRP calculations, G/T measurements, path loss modeling and spectrum analysis.
• Experience with SATCOM systems, terrestrial wireless networks, SIGINT or EW systems.
• Experience designing and implementing algorithms for signal detection, frequency estimation, power estimation, channel characterization, noise/interference mitigation, and direction finding.
• Experience developing methods and systems to estimate transmitter EIRP from collected RF measurements, calibrate measurement systems, correct for propagation losses, account for antenna gain patterns, and quantify measurement uncertainty.
• Familiarity with Linux development environments, Git, CI/CD workflows, containerization (Docker), Ansible, and Cobbler.
• Ability to define measurement requirements, develop verification and validation plans, analyze system performance, and support field testing and data collection campaigns.
• Experience working across multidisciplinary teams with RF engineers, antenna engineers, software engineers, and test engineers.
• Experience processing IQ sample data, spectral data, and telemetry and measurement datasets.
• Strong understanding of FFTs, digital filtering, estimation theory, statistical signal processing.
• Ability to validate measured EIRP against theoretical link budget predictions.
• Experience analyzing field-collected RF measurement data.
• Experience generating RF coverage and EIRP maps.
• Familiarity with Geographic Information System (GIS) concepts, Terrain databases, Geospatial coordinate systems, digital elevation models (DEM).
• Ability to develop visualization products showing coverage contours, signal strength heat maps, EIRP distribution, measurement confidence intervals.
• Experience building scalable data-processing pipelines.
• Experience with SATCOM software and systems.
• Experience with geolocation and emitter characterization techniques.
• Familiarity with NSA software.
• Experience with airborne or spaceborne RF sensing systems.
