About this role
Cisco is a leading company in the field of data and infrastructure solutions, and they are seeking a Principal DSP Engineer to join their Acacia team. The role involves developing advanced DSP and FEC algorithms for optical transceivers while collaborating with various teams to optimize performance and power efficiency.
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
Requirements:
- 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
- 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
