Cisco Principal DSP Engineer – Coherent Optical Transmission Systems 

United States, Massachusetts 

915093369

Job posting may be removed earlier if the position is filled or if a sufficient number of applications are received.

With your expertise in DSP for coherent optical transceivers, FEC, and modeling, you help the team to develop the next generation of low-power and high-performance coherent transceivers. Here are some examples of possible topics:

• 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

Typically: Bachelors + 15 years of related experience, or Masters + 12 years of related experience, or PhD + 8 years of related experience

• + 10 years of industry experience in related fields.
• Experience with Digital Signal Processing (DSP) and/or Forward Error Correction (FEC) for coherent optical communications.
• Experience 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.

• A master's or Ph.D. degree in mathematics, physics, or electrical engineering is highly recommended, although not strictly required.
• Experience with C++, Linux, and version control systems, specifically SVN and Perforce.
• Experience with Verilog or VHDL, and/or collaboration with ASIC designers.
• Experience presenting technical information to colleagues.
