What does a typical day look like?

• The SDR Engineer will be responsible for design, development, and testing of all SDR software including its FPGA and host interface.
• Evaluating SDRs for incorporation into our payload and spacecraft systems
• Understanding the hardware-based requirements of SDRs, e.g., FPGA size, speed, internal clock stability, I/O interfaces, sample rates, dynamic range, radio chip architecture, gains and filtering as the signal progresses within the SDR.
• Designing and evaluating DSP algorithms for satellite communication systems
• Updating or creating host interface software to interact with the SDRs
• Developing test software and drivers to support unit, integration, and system testing of all SDR software functions
• Writing this software in C, C++, or other languages in a Linux environment
• Working with other software team members to benchmark payload software applications
• Testing and validating hardware blocks both in simulation and on target
• Developing and maintaining documentation and ICDs for in-house IP blocks and other SDR related software

What qualifications are they looking for?

• A Master’s degree (or better) in Electrical/Computer Engineering or related field
• Excellent foundation in DSP and Communication Theory
• At least three years of recent experience working with SDRs
• In-depth knowledge of digital signal processing (DSP) algorithms and communication theory (e.g., filter design, clock recovery, signal detection, channel estimation and equalization)
• Experience with implementing DSP algorithms in C/C++
• Experience with device drivers
• Ability to create testbenches for benchmarking and testing
• Knowledge in PHY and MAC layers of cellular standards (e.g., GSM, LTE, 5G) is a plus.
• Experience with implementing DSP algorithms in FPGAs is a plus, but optional
• Experience using lab equipment for testing and validation
• Experience with evaluating SDR platforms and specifications
