Rebellions | 리벨리온대한민국 경기도 성남시 분당구 정자일로 248, 18층 리벨리온
Responsibilities and Opportunities
Bring-up and Characterization: Lead the bring-up, electrical characterization, and functional validation of various high-speed interfaces, including SerDes PHYs (PCIe, CXL, Ethernet), High Bandwidth Memory (HBM3E/DDR), and high-speed clocking networks
Compliance and Interoperability: Conduct thorough compliance and interoperability testing for key industry-standard interfaces to ensure strict adherence to electrical specifications and protocol requirements
Measurement and Analysis: Perform detailed lab measurements utilizing specialized test equipment (Oscilloscopes, BERTs, VNAs) for jitter analysis, eye diagram analysis, link margin characterization, and system-level margin analysis
Debugging and Root Cause Analysis: Collaborate cross-functionally with ASIC, SI, and Firmware teams to effectively debug complex IO issues, identify the root cause of performance degradation (e.g., link training failures, marginal timing, BER issues), and drive resolutions
Documentation: Create detailed test plans, validation reports, and technical documentation summarizing test results, compliance status, and observed failures
Key Qualifications
Bachelor's or higher degree in Electrical Engineering, or a related field
Minimum of 5 years of hands-on experience in high-speed IO validation, electrical characterization, and system debug, specifically focused on interfaces operating at multi-Gbps speeds(e.g., 100 Gbps/lane SerDes, HBM/DDR interfaces), including SerDes PHY performance validation such as TX equalization tuning, receiver adaptation, and eye/jitter margin optimization
Equipment Mastery (Must-Have): Expert proficiency in setting up, operating, and automating high-speed test equipment:
Real-time/Sampling Oscilloscopes (for Eye and Jitter analysis)
Vector Network Analyzers (VNA) / Time Domain Reflectometers (TDR)
Strong working knowledge of physical layer architecture, equalization techniques (CTLE, DFE, FFE), and the operation of high-speed protocols (PCIe, CXL, Ethernet)
Understanding of firmware/driver architecture and their interaction with hardware systems
