DSP - FEC Design Engineer

The role

This person will research, develop, and evaluate forward error correction (FEC) schemes for high-speed optical communication systems. They will design soft-decision FEC algorithms and develop simulation models for algorithm verification.

What you will do

• Research, develop, and evaluate forward error correction (FEC) schemes for high-speed optical communication systems.
• Design and optimize soft-decision FEC algorithms suitable for high-throughput optical modem implementations.
• Develop and evaluate coding schemes such as LDPC, staircase codes, or related high-performance FEC architectures.
• Model and simulate FEC performance in optical communication systems.
• Analyze performance trade-offs including coding gain, latency, throughput, and implementation complexity.
• Develop floating-point and fixed-point simulation models for algorithm verification.
• Implement bit-accurate and cycle-accurate models supporting ASIC implementation.
• Collaborate closely with DSP, ASIC, firmware, and verification teams.
• Document algorithm design and simulation results.

Required qualifications
