• • Make hands-on technical contributions to unblock critical design, validation, and customer issues in a dynamic, fast-paced environment. 

• High-Speed SerDes Validation 

• • Direct ASIC Power-On and bring-up, silicon/PCB debug, PVT characterization, margin analysis, and performance optimization across voltage, temperature, channel, and workload conditions. 

• • Validate high-speed NRZ and PAM4 SerDes-based protocols, including PCIe Gen 3 and above 

• • Apply signal/power integrity, SerDes/PHY knowledge, coding, and lab expertise to identify risks and drive practical solutions across circuits, power distribution, connectors, sockets, and cables. 

• Cross-Functional and Customer Execution 

• • Partner with ASIC, system validation, firmware, systems, mechanical, thermal, quality, compliance, manufacturing, and customer engineering teams to deliver robust products. 

• • Engage key internal customers to understand system requirements, evaluate form factors, propose complete board solutions, and resolve issues through production support. 

• • Collaborate with external vendors for test equipment, bench sockets, temperature forcing units, RF cables, PCB vendors, and related suppliers to ensure validation platforms are automated, robust, and scalable. 

• Team Development and Productization 

• • Build, mentor, and develop a high-performing engineering team while establishing clear ownership, technical standards, and execution mechanisms. 

• • Drive products from concept to mass production, including validation data reviews, code/automatin reviews, validation reporting, documentation, and post-production support. 

• • Improve post-Silicon development processes and methodologies, share lessons learned, and reuse validation best practices across Astera Labs’ connectivity and memory product portfolio. 

Basic Qualifications 

• Bachelor’s degree in Electrical Engineering or a related technical field. Master’s degree in Electrical Engineering preferred. 

• 12 - 15+ years of relevant experience, consistent with Astera Labs’ standardized Director level. 

• Technical management experience leading design, validation, product, or system engineering teams. 

• Experience with high-speed serdes PHY Validation over PVT conditions and taking products from concept to validation plan, validation, production release and post-production support.  

• Strong background in high-speed SerDes IP validation and PHY tuning, signal/power integrity, and automation using common lab equipment such as high-speed oscilloscopes, BERTs, and VNAs 

• Entrepreneurial, open-minded behavior and can-do attitude. Think and act with the customer in mind! 

• Strong cross-functional collaboration, technical communication, prioritization, and independent problem-solving skills. 

Preferred Qualifications.
