• Write with clarity detailed HW specifications, SI simulation and measurement test plans, and test reports
• Drive PCB placement and layout for robust SI performance
• Design, layout, and characterize high speed Integrated SerDes circuits in various channel environments spanning multiple PCBs and high speed connectors
• Evaluate SerDes interconnect PHY topologies, transmitter and receiver capabilities, parameter tuning, and related clocking / power supply considerations to meet critical performance and robustness objectives
• Design with high emphasis on noise, jitter, and signal crosstalk suppression
• Design with high emphasis on compact size/miniaturization appropriate for dense boards with multiple optical/electronic channels in parallel.
• Drive supplier collaborations to optimize for SI performance. Suppliers would include both external component vendors and internal (INFN ASICs).
• Work with EMI compliance engineers and define PCB design rules for EMI

Required Experience and Qualification

• Expert level skill in Ansys HFSS EM analysis for 10-100GHz channels.
• Deep understanding of transmission line theory
• 7+ years of direct experience with PCB and package geometry optimization with EM tools
• Create PCB routing guideline based on the PCB geometry optimization and channel simulation.
• Experience in high speed channel measurement with VNA and TDR, and the technique of de-embedding test fixture.
• Experience in 56Gbps SerDes design and debug, understanding of transmitter and receiver equalization, CDR behavior, modeling, and link training algorithms.
• M.S. degree in electrical engineering or physics with minimum 10 years of industrial experience in signal integrity.

Preferred Experience and Qualification

• Experience in defining PCB stack-up, material selection and trade-offs for 112Gbps channels
• Experience in SerDes channel simulation at 112Gbps data rate with Keysight/Ansys tools.
• Experience in methodologies to achieve good correlation between simulation and measurement for PCB channels at 112Gbps or higher.
• Experience in component selection/evaluation for 112Gbps SerDes including but not limited to SerDes IP, re-timer/repeater, connectors, DC blocking caps, and etc.
• Experience in PCB design guideline for EMI. 
• Experience in power integrity simulations and lab measurement verification
• Experience in high speed backplane design desirable

“This position requires direct or indirect access to certain confidential information, hardware, software, technology, or technical information (referred to here as “Export-Controlled Information”) controlled under the U.S. International Traffic in Arms Regulations (ITAR) and/or the U.S. Export Administration Regulations (EAR). All personnel in this position must be eligible to or be able to obtain authorization from the appropriate agency to access applicable Export-Controlled Information. The U.S. Department of Commerce currently requires a foreign person with a most recent citizenship or permanent residency of Sudan, Ukraine, or a country currently designated in Country Group D:1, E:1 or E:2 (Supplement No. 1 to Part 740, Title 15) to have an export control license to access our Export-Controlled Information, unless they meet certain exemptions provided under U.S. export control laws and regulations. The list of applicable countries in Country Group D:1, E:1 or E:2 may be updated by the U.S. government from time to time. The current processing time for an export control license is approximately 4 to 6 months.

Your employment or engagement with Infinera shall be contingent on verifying your eligibility or requirement for obtaining a necessary license and/or authorization from the appropriate agency. You will be required to provide certain information for export control compliance assessment purposes, and your information will be reviewed by Infinera's hiring and export control teams to ensure compliance with the U.S. export control laws and regulations. Infinera will collect necessary documents (such as proof of citizenship etc.) to assess license/authorization requirements if you are offered and accept the position.”
