The Opportunity:
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.

Responsibilities:

•              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.

Qualifications:

Required: 
•              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

Desired:
•             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)
