DSP System Architect

Credo Technology Group • San Jose, CA

77d • $110,000 - $200,000

About The Position

We are seeking a DSP System Architect to optimize digital signal processing (DSP) architectures for high-speed SerDes (Serializer/Deserializer) transceivers. This role defines system-level architecture, algorithms, and performance needs. The architect will work closely with cross-functional teams to debug, analyze data and bring SerDes solutions to market.

Requirements

• Master's degree or PhD in Electrical Engineering, Computer Engineering, or a related field.
• 0-7+ years of experience in DSP system architecture and algorithm development for high-speed SerDes or communication systems.
• Understanding of digital communication and signal processing theory, including channel equalization techniques (e.g., FFE, DFE), timing recovery and CDR (Clock and Data Recovery) architectures, detection and estimation theory, adaptive algorithms and system identification.
• Proficiency in communication system modeling using tools like MATLAB, Simulink, C, and/or Python.
• Experience with high-speed serial data protocols (e.g., NRZ, PAM4) and relevant industry standards.
• Familiarity with mixed-signal circuit design concepts and their impact on DSP performance.
• Experience in guiding and testing the transfer of algorithms from high-level models to RTL implementation.
• Communication, problem-solving, and collaboration skills.

Nice To Haves

• Experience with advanced modulation formats (e.g., PAM4).
• Experience with ADC-based wireline transceivers and/or coherent DSP architectures.
• Familiarity with FEC (Forward Error Correction) techniques, such as RS or LDPC codes.
• Familiarity with lab equipment for testing high-speed serial links (e.g., oscilloscopes, spectrum analyzers).
• Experience with machine learning concepts and their application in DSP.
• Knowledge of analog mixed-signal circuit design concepts.
• Experience in firmware or embedded software development.

Responsibilities

• Collaborate with analog, digital, and mixed-signal design teams to implement DSP solutions.
• Collaborate with application and firmware team participate in silicon bring-up and debugging by analyzing data and provide guidance on test plans for lab characterization and verification.
• Assist customers on system-level performance and algorithmic issues.
• Define and design DSP architectures for high-speed SerDes and optical transceivers.
• Develop and maintain end-to-end system models using tools like MATLAB, Simulink, C, and/or Python.
• Design and simulate DSP algorithms for signal processing in high-speed links, including equalization, timing recovery, and error correction (FEC).
• Perform research and development activities to advance DSP for SerDes and optical channels.
• Develop and perform behavioral modeling of mixed-signal circuit designs for transceivers.
