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.

Key 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.

Basic Qualifications

• 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.

Preferred Skills:

• 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.
