AI generated summary

  • You should have 10+ years in DSP/FEC for optics, system modeling, C/C++/Python skills, a relevant degree, and familiarity with Linux, SVN, Verilog/VHDL, plus experience in optical communication systems.
  • You will design, test, and optimize DSP/FEC algorithms, validate performance on hardware, model RF/optical components, and analyze transceiver performance against simulations.

Requirements

  • At least 10 years of industry experience in related fields.
  • Experience with Digital Signal Processing (DSP) and/or Forward Error Correction (FEC) for optical communications.
  • Proficiency in modeling communication systems.
  • Programming experience in C/C++, Python, Matlab, or similar languages.
  • A master's or Ph.D. degree in mathematics, physics, or electrical engineering is highly recommended, although not strictly required.
  • Familiarity with C++, Linux, and version control systems, specifically SVN and Perforce.
  • Experience with Verilog or VHDL, and/or collaboration with ASIC designers.
  • Experience with coherent and direct-detect optical communication systems.
  • Practice effectively presenting technical information to colleagues.

Responsibilities

  • Invent, simulate and validate new DSP or FEC algorithms (both in floating-point and fixed-point precision) to improve performance and functionality or lower power consumption
  • Test and optimize these algorithms on actual hardware and correlate performance with previous simulations
  • Develop models of analog RF and optical components and evaluate system performance with these models
  • Analyze performance of developed transceiver modules and update models and simulation environments to accurately match the measured results
