Cisco Technical Leader DSP Engineer – Coherent Optical Transmission Systems 

United States, Georgia, Atlanta 

282404975

The application window is expected to close on 5/31/25.

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

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

• Design, 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
• Work closely with the optical testing and firmware teams to develop robust algorithms for calibration and run-time optimization of the transceivers

• Bachelor's +12 years of related experience, or Master's +8 years of experience, or PhD +5 years of industry experience in related fields.
• A master's or PhD degree in mathematics, physics, electrical engineering or related fields.
• Proficiency in modeling communication systems or simulating digital signal processing algorithms.
• Programming experience in C/C++, Python, Matlab, or similar languages.

• Experience with Digital Signal Processing (DSP) and/or Forward Error Correction (FEC) for optical communications.
• Familiarity with C++, Linux, and version control systems, specifically SVN and Perforce.
• Experience working in a lab for optical communications.
• Experience with coherent and direct-detect optical communication systems
• Practice effectively presenting technical information to colleagues.
