Job Title:

DSP Software Engineer

Location:

Evergreen, CO

Clearance:

TS SCI

Travel:

Minimal

Description:

Work in a small team environment to develop signal chain processing libraries for driving the next generation of TapHere! SDR solutions. Candidate will develop libraries and modules for a variety of programs, generating building blocks for the TapHere! Radio foundational architecture. Work will be done from the TapHere! Radio Lab, with occasional travel to customer sites.

Experience Required:

• BS degree in STEM field supporting an Information Systems Science role (examples include Electrical Engineering, Mathematics, Computer Science, etc.) preferred
• 2-3+ years of professional experience writing general purpose CPU-based DSP code for RF radio signal processing; using MATLAB for proof of concept and C or C++ or C# for final implementation
• Experience creating software filters (FIR, IIR, comb, multirate etc.)
• Experience creating software radio functions such as AGC, received power calculations, phase/frequency correction
• Experience creating software demodulators and modulators (PSK, FSK, QAM, AM, FM, MSK, etc.)
• Experience creating software error coding routines (FEC such as Reed Solomon, CRC, etc.)
• Experience with software defined radio signal chain design
• Good understanding of Information System Sciences from a signals perspective (correlation, convolution, FFTs, bit error rate, constellations, etc.)

Desired Additional Experience (Optional)

• SATCOM Systems

• Convolutional coding (Viterbi, etc.)

• Radar signal processing

• Cognitive radio functions

• Phased Array techniques (beamforming, adaptive nulling)

• MIMO

• Spread Spectrum and PN Coding

• Familiarity with wireless communication protocols/standards/concepts such as 802.11xx, TDMA, CDMA, LTE, MANET, etc.

• Usage of common lab equipment for digital communication signal analysis (spectrum analyzers, vector signal analyzers, oscilloscopes, etc.)

• Comfortable working in both Linux and Windows environments

Skills Required:

• MATLAB and C or C++ or C#
• Ability to convert signal processing concepts such as transform theory, sampling theory, filter theory, common signal processing operations (correlation, convolution, etc) into actual software implementations
