Job description

Overview

Location: USA – Austin, TX and San Francisco Bay Area (Full-Time)

Work Type: Onsite / Hybrid (Based on Project Needs)

Experience Required: 5+ Years in DSP and ECC Algorithm Design

Compensation: USD 160,000 – 180,000 (plus benefits and stock options)

Job Overview: Our client, a Series-D semiconductor innovator, specializes in programmable coherent DSP solutions that power the next generation of cloud and AI infrastructure. Backed by top-tier investors such as Kleiner Perkins, Spark Capital, Mayfield, and Fidelity, the company recently exited stealth mode with $180M in funding. This position seeks a senior Algorithm Engineer with deep expertise in Error Correction Codes (ECC) for the optical communication market. The selected candidate will play a pivotal role in designing, simulating, and optimizing ECC algorithms for cutting-edge coherent optical transceivers operating at data rates up to 1600 Gbps.

Responsibilities

• Design and simulate ECC architectures, defining key capabilities and performance metrics for implementation.
• Develop, model, and optimize ECC algorithms in MATLAB and C, integrating them with MODEM simulations.
• Collaborate with VLSI, System, Firmware, and Design Verification teams to align on specifications and system-level design.
• Translate algorithmic models into fixed-point representations suitable for hardware (RTL) implementation.
• Partner with digital and firmware designers to ensure accurate and efficient architecture implementation.
• Conduct lab-based validation, debugging, and tuning of ECC and DSP algorithms to ensure optimal system performance.

Must-Have Requirements

• Minimum 5 years of hands-on experience in ECC algorithm design and implementation.
• Strong proficiency in MATLAB and C/C++ for digital signal modeling and testing.
• Deep understanding of DSP systems and hardware implementation constraints (MATLAB-to-RTL flow).
• Proven track record in simulating, validating, and optimizing ECC algorithms.
• Practical lab experience in debugging and performance tuning of algorithms.

Nice-to-Have Skills

• Prior experience with Optical Communication Systems or Coherent DSP.
• Familiarity with high-speed DCI (Data Center Interconnect) architectures.
• Exposure to forward error correction schemes for communication hardware.
• Understanding of modulation techniques, system simulations, and VLSI integration workflows.
