高级应用工程师

该职位来源于猎聘 Position Description:

• Develop and execute comprehensive validation plans for high-speed transceivers and DSP chips, covering optical and system-level testing.
• Perform compliance, performance, and interoperability testing for high-speed signaling such as 100G/200G PAM4.
• Tune and validate the performance of optical sub-components (e.g., TX drivers, PICs, TIAs).
• Develop and maintain a test automation framework for validation regression, data collection, and data analysis, using Python, C#, or similar languages.
• Conduct environmental and reliability stress testing, including thermal cycling, voltage margining, and soak tests.
• Analyze test data, identify root causes of failures, and drive issues to resolution with cross-functional teams.
• Support platforms bring-up, firmware validation, and vendor qualification for high-speed modules.
• Contribute to DSP bring-up and tuning, including developing low-level code for signal processing and link optimization.
• Apply knowledge of optical components, modulation schemes, and optical communication principles to system validation.
• Contribute to validation hardware design, including schematic review and board-level bring-up Preferred Qualifications:
• Bachelor’s or higher degree in Electrical Engineering, Optical Engineering, Communications, or a related field.
• Hands-on experience in validating high-speed transceivers using lab equipment such as oscilloscopes, BERTs, and spectrum analyzers.
• Hands-on experience in tuning and validating optical components (e.g., laser drivers, TIAs, PICs).
• Familiarity with the CMIS interface and a solid understanding of signal integrity fundamentals.
• Hands-on experience with optical module testing and validation is highly preferred.
• Proficiency in Python, C#, or C for developing test automation, data processing, and analysis tools.
• Strong problem-solving skills and the ability to work both independently and collaboratively.
• Excellent communication skills and a proven ability to collaborate effectively with cross-functional teams.
• Passion for high-speed signaling, system-level validation, and continuous learning.
• Solid understanding of high-speed link architectures and behavior, including SerDes and DSP, with the ability to write bring-up, tuning, and validation code.
