About The Position

CACI is seeking experienced DSP Communications Engineers who are passionate about working closely with customers to solve difficult mission-critical challenges. This position entails the design and implementation of RF signal processing, communications modems and related algorithms, in a software-defined radio environment for ground-based software implementations and space-based embedded systems.

Requirements

5+ years of related work experience with at least a Bachelor's degree in Electrical Engineering (or equivalent), with an emphasis in communications systems, coding, and digital signal processing.
Familiar with digital signal processing (DSP) for things such as filter design and link-level simulation.
Deep understanding of modern communication systems, including digital communications, source and channel coding, detection, equalization, timing and carrier recovery, and common forms of feedforward estimation.
Experience with communications and signal processing algorithm and channel modeling and simulation in Python or Matlab.
Basic knowledge of C/C++ programming with a willingness to become proficient if hired.
All candidates must be U.S. citizens with the ability to obtain a security clearance.

Nice To Haves

Current TS/SCI security clearance.
Advanced degree in Electrical Engineering or related field with an emphasis in communications systems and signal processing.
Familiar with satellite RF communications systems, telemetry, tracking, and control (TT&C) standards, including universal S-band (USB), Tracking and Data Relay Satellite (TDRS), and the Space Ground Link System (SGLS).
Conversant in satellite air interface standards, such as the various DVB and CCSDS specifications.
Conversant in methods and techniques for carrier and symbol acquisition, including phase locked loops (PLLs), open loop maximum likelihood (ML) estimation, and other common estimation techniques.
Familiarity with Python, including the MATLAB-like features of Python is a plus.

Responsibilities

Contribute to the design of modulators, demodulators and synchronization algorithms for RF communication waveforms
Implement modern forms of channel coding, including trellis coded modulation and decoding, low density parity check coding (LDPC) and turbo coding.
Design and implement new RF signal processing capabilities and waveforms for advanced applications including signal monitoring, detection, and parameter estimation
Model algorithms and waveforms in Python and/or Matlab, and deploy them in a C/C++ environment.
Present research, models and test results to non-technical audiences in a clear, concise form.
Work closely with software, firmware, and hardware team members to deploy functional implementations on CACI’s software-defined radio platforms.
