Ciena enables next-generation high-speed connectivity through advanced optical communication innovation and a people-first culture. This role contributes to the architecture and development of coherent DSP solutions for 800G/1.6T transmission systems and beyond. The position plays a key role in advancing DSP ASIC technologies that power market-leading optical platforms.
How you will make an impact:
  • Define system architecture for high-speed optical DSP chips, optimizing data rates and power consumption
  • Develop DSP algorithms for equalization, error correction, clock data recovery (CDR), and signal optimization
  • Collaborate with hardware, firmware, and chip design teams to optimize performance, power, and silicon area
  • Perform system-level modeling and simulation to validate DSP algorithms and architectures
  • Partner with photonics and RF teams to enable DSP and optical front-end integration
  • Establish performance metrics, validation methodologies, and compliance with optical communication standards
  • Engage with customers and industry partners to align DSP innovation with market requirements.

The must haves:
  • Education: Ph.D. in Electrical Engineering, Computer Engineering, or a related field.
  • Experience: 5+ years of industry experience in DSP algorithm development, system architecture, and ASIC design for optical communications
  • Application of digital signal processing, communication theory, and error correction codes
  • Collaboration within globally distributed, multinational engineering teams
  • Utilization of MATLAB, Python, and C/C++ for DSP simulation and algorithm development
  • Knowledge of ASIC and FPGA design and system-on-chip integration using VHDL and related chip design flows
  • Experience with photonic ICs and DSP co-design.

Nice to haves:
  • Awareness of optical industry standards such as OIF and interoperability requirements
  • Experience working across cross-functional engineering teams in product development environments.
