We are seeking an experienced
Optical DSP Chief Architect
to lead the system architect of cutting-edge Digital Signal Processing (DSP) solutions for high-speed optical communication systems. The ideal candidate will play a critical role in defining system architecture, optimizing performance, and collaborating with cross-functional teams to develop next-generation optical transceivers and communication chips.

Key Responsibilities:

  • Define the system architecture for optical DSP chips used in high-speed optical communication networks (800G/1.6T and beyond).
  • Improve the algorithms for equalization, error correction, clock and data recovery, and other signal processing functions.
  • Work closely with hardware, firmware, and Chip architect to optimize DSP implementation for performance, power, and area.
  • Conduct system-level modelling and simulations to validate DSP algorithms and architectures.
  • Collaborate with photonics and RF teams to ensure seamless integration of DSP with optical front-end components.
  • Define key performance metrics and validation methodologies for DSP architectures.
  • Work with customers and industry partners to align DSP architectures with market needs and emerging technologies.
  • Continuously monitor and adopt advancements in optical communications, DSP methodologies, and semiconductor technologies

Requirements:

Qualifications & Experience:

  • Education: Master’s or Ph.D. in Electrical Engineering, Computer Engineering, or a related field.
  • Experience: Minimum of 10-15 years of experience in DSP algorithm development, system architecture, and ASIC design for optical communication systems
  • Technical Expertise:
  • Strong background in digital signal processing, communication theory, and error correction codes.
  • Hands-on experience with MATLAB, Python, or C/C++ for algorithm development and simulations.
  • Knowledge of ASIC design
  • Familiarity with optical communication standards such as OIF and others
  • Experience with high-speed SerDes, ADC/DAC interfaces, and mixed-signal design considerations.
  • Understanding of optical modulation techniques and coherent optical transmission.

Preferred Skills:

  • Strong leadership and communication skills, with the ability to motivate and inspire a diverse team.
  • Knowledge of photonic integrated circuits and co-design with DSP.
  • Experience with real-time embedded DSP implementations.
  • Proven track record of delivering high-performance DSP architectures in commercial optical products.
