DSP - FEC Design Engineer

The ideal candidate must have a strong theoretical background in coding theory, digital communications, and error correction techniques, with experience developing high-performance forward error correction (FEC) algorithms for high-speed communication systems. Candidates with industry experience are preferred.

Key Responsibilities
• 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, including interaction with DSP blocks and channel impairments.
• 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 to ensure efficient hardware implementation.
• Document algorithm design and simulation results.

Preferred Qualifications
• Master's or Ph.D. degree in Electrical Engineering, Mathematics, Computer Engineering, or related field.
• Strong background in coding theory and error correction algorithms.
• Experience with FEC schemes for communication systems, particularly soft-decision FEC.
• Familiarity with LDPC, staircase codes, product codes, or related modern FEC techniques.
• Experience evaluating coding gain, BER performance, and decoder complexity.
• Programming experience in C/C++, Python, MATLAB, or similar languages.
• Experience in modeling communication systems.
• Familiarity with DSP algorithms for communication systems.
• Experience with version control systems, specifically GitHub.
• Familiarity with hardware implementation considerations and languages such as Verilog or VHDL is a plus.
• Team player with a mindset focused on the successful delivery of the first product.
