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.

• 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.

Required:

• 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 feed forward 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.

Desired:

• 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.
