Senior Signal Integrity Engineer

The role

This person will lead board-level high-speed electrical design and validation for 1.6T DR8 OSFP optical modules. They will own SI/PI architecture, lead simulations, and mentor the SI team.

What you will do

• Own SI/PI architecture and strategy for 1.6T DR8 OSFP modules
• Lead pre- and post-layout SI/PI simulations and reviews
• Define PCB stack-ups, materials, via and breakout strategies, connector selections, and routing guidelines
• Drive cross-functional technical decisions with hardware, optics, mechanical, FW, and test teams
• Lead lab correlation and validation plans
• Provide technical leadership for SI-related debug on proto and field issues
• Establish and maintain company-wide SI/PI design methodologies, checklists, and documentation
• Mentor and coach junior and mid-level SI/hardware engineers

Required qualifications

• B.E/B.Tech or M.E/M.Tech (or equivalent) in Electrical/Electronics Engineering
• 15–20 years of relevant high-speed SI/PI and board-level design experience
• Deep expertise in very high-speed SerDes (≥56G)
• Extensive hands-on experience with leading SI/PI tools (e.g., Sigrity, ADS, HFSS, SIwave, HSPICE or equivalents) and scripting/automation
• Proven track record bringing complex high-speed hardware or optical modules from concept through production
• Strong lab expertise with high-bandwidth scopes, VNAs, BERTs, and TDRs

Nice to have

• 100G/200G PAM4 SerDes expertise
• Direct experience with OSFP/OSFP-XD/QSFP-DD optical transceiver designs at 800G/1.6T or similar data-center interconnects
• Knowledge of IEEE 802.3 DR8/FR8/LR8-class electrical/optical standards and relevant MSAs/OIF specifications
• Background in EMI/EMC, mechanical and thermal considerations for pluggable modules
• Experience managing or technically leading small SI/PI or hardware teams

Benefits

• Competitive salary commensurate with experience
• Comprehensive benefits package including health insurance
• Professional development opportunities and certification support
• Access to cutting-edge technology and cloud platforms
• Collaborative work environment with cross-functional teams
