AMERGINT Technologies is seeking an experienced Senior Communications System Engineer with an emphasis in channel coding.  This position entails the design and implementation of modems and related algorithms, in a software radio environment.  In this role, the engineer will be responsible for distilling a waveform description into a working channel encoder, transmitter, receiver, and channel decoder, implemented in a software radio platform, using C++ and Python.

This position will be located in Colorado Springs or Broomfield, CO or Huntsville, AL, or remote.

What You Will Get To Do

  • You’ll be expected to be conversant in legacy and modern forms of channel coding, including trellis coded modulation and decoding, low density parity check coding (LDPC) and turbo coding.
  • Interpret, understand, and implement channel encoding and decoding algorithms for the aforementioned channel coding methodologies in a software radio platform.
  • Conversant in satellite air interface standards, such as the various DVB and CCSDS specifications.
  • Contribute to the design of modulators and demodulators for waveforms such as M-PSK, M-APSK, M-QAM, M-ary FSK, and variations on continuous phase modulation (CPM), e.g. GMSK.
  • Should be 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.


  • 10 Years of related work experience with at least a Master’s degree in Electrical Engineering (or equivalent), with an emphasis is communications systems, coding, and digital signal processing.
  • Familiar with digital signal processing (DSP) for things such as filter design and link-level simulation.
  • Conversant with 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.


  • PhD in Electrical Engineering or related field.
  • Active Secret security clearance.
  • Familiar with 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).
  • Knowledgeable with range telemetry standards such as IRIG-106, including PCM/FM, shaped offset QPSK (SOQPSK), and multi-h CPM.
  • Familiarity with Python, including the MATLAB-like features of Python is a plus.
  • Familiarity with MATLAB is a plus.
