DSP Engineer (Digital Signal Processing)

DSP Engineer (Digital Signal Processing)

Alén Space

Nigrán, Spain

We´re expanding our team at Alén Space, and are looking for a DSP Engineer; with passion in what you do, talented and experienced. You will be part of a multidisciplinary team of software, FPGA, and digital signal processing engineers and will support the implementation of DSP (Digital Signal Processing) algorithms in programmable devices (FPGAs).

What you will be doing?

• Design digital communication systems using platforms including software defined radios (SDRs) and FPGAs.
• Functional modeling of DSP algorithms and their implementation in RTL (Verilog/VHDL) or high-level languages (C/C++).
• Support the evolution of our custom space-tailored radio platforms.
• Main languages/technologies used:
  • Verilog/SystemVerilog.
  • Yosys/Xilinx Vivado.
  • Python.
  • C/C++.
  • GNURadio.
• Examples of existing applications already developed by Alén Space:
  • DVB-S2 transmitter in Verilog.
  • ADS-B receiver in Verilog.
  • AIS receiver, hybrid between FPGA (VHF channelizer) and CPU (GNURadio/C++).
  • Proprietary M2M modem implemented in C.

What do we need in our team

• Bachelor or Master’s degree in Telecommunications Engineering.
• More than 3 years of experience in developing signal processing algorithms for communication systems in Python, C/C++ or Matlab using both floating point and fixed-point design techniques.
• Experience in migrating modeled algorithms to implementations in FPGAs or SDR frameworks.
• Understanding of RF concepts such as AGC, noise figure, power amplifiers, phase noise, PLL, oscillators/mixers.

Valuable knowledge:

• Expertise with Software-Defined Radios (SDR) frameworks such as GNU Radio.
• Experience with Xilinx Zynq or Xilinx Zynq UltraScale+ series FPGAs, Analog Devices AD9361, and other common RF chipsets.
• Some experience with Python or other scripting languages.
• Knowledge of coding theory and techniques: LDPC, Turbo codes…
