DSP - Optical Design Engineer

Locations: Ottawa, Ontario, Canada or Vancouver, British Columbia, Canada

Key Responsibilities
• Research, develop, and evaluate digital signal processing (DSP) algorithms for high-speed optical communication systems.
• Design and optimize DSP blocks used in optical transceivers, including adaptive equalization, timing recovery, carrier phase recovery, polarization demultiplexing, and nonlinear compensation.
• Develop system-level simulation models of optical communication links and evaluate DSP algorithm performance under realistic channel conditions.
• Analyze performance under various impairments such as noise, chromatic dispersion, polarization effects, and hardware non-idealities.
• Verify and optimize algorithm performance through floating-point and fixed-point simulations.
• Develop bit-accurate and cycle-accurate models to support ASIC implementation.
• Document design details and collaborate with ASIC, firmware, and verification teams to ensure reliable implementation in silicon.

Preferred Qualifications
• Master's or Ph.D. degree in Electrical Engineering, Physics, or Mathematics.
• Minimum of two years of industry experience in related fields.
• Strong background in digital signal processing and digital communications.
• Experience with DSP algorithms for optical communication systems.
• Programming experience in C/C++, Python, MATLAB, or similar languages.
• Experience in modeling communication systems.
• Familiarity with forward error correction (FEC) schemes used in communication systems.
• Experience modeling optical components and electrical frontends of optical transceivers.
• Experience with version control systems, specifically GitHub.
• Familiarity with Verilog or VHDL is a plus.
• Team player with a mindset focused on the successful delivery of the first product.
