Asic Engineering Layout Leader | Custom Ic Layout, Analog @ Cisco

At Cisco Systems , the Client Optics Group (COG) Engineering team is at the forefront of building next-generation optical interconnect solutions powering high-speed networking. The team focuses on delivering cutting-edge 100G, 200G, and 400G per lambda technologies that enable scalable, high-performance data movement across modern infrastructure.

As a Layout Lead, you will work within a highly collaborative, cross-functional environment alongside analog and mixed-signal designers, digital engineers, packaging experts, process technologists, and validation teams. Together, you will drive end-to-end development of complex silicon solutions that are critical to Cisco s innovation in optics and high-speed connectivity.

In this role, you will provide technical leadership and drive the physical implementation of high-performance analog and mixed-signal designs from concept through tapeout.

You will:

• Lead end-to-end layout development for complex analog, mixed-signal, and high-speed circuits including SerDes and PAM4 interfaces
• Own block-level and top-level floorplanning, placement, routing, and integration
• Translate circuit schematics and performance requirements into optimized, manufacturable layouts
• Optimize designs for parasitics, matching, signal integrity, power integrity, thermal behavior, and yield
• Ensure compliance with all physical verification requirements (DRC, LVS, ERC, EM/IR, density, reliability)
• Drive integration across analog, digital, and high-speed domains including clocking and control logic
• Support post-layout extraction, simulation closure, and tapeout readiness
• Partner with packaging teams on bump planning, pad ring, ESD, and overall package integration
• Identify and resolve layout challenges impacting performance, yield, or manufacturability
• Lead design reviews, assess trade-offs, and mitigate tapeout risks
• Improve layout methodologies, flows, and automation in collaboration with CAD teams
• Mentor junior engineers and strengthen layout best practices across the team
• Support silicon bring-up, debug, and failure analysis

• Bachelor s or Master s degree in Electrical Engineering or a related field
• 7+ years of experience in custom IC layout (analog, mixed-signal, or high-speed designs)
• Proven experience leading block-level or top-level layout through full tapeout cycles
• Strong expertise in custom layout, parasitic-aware design, and physical verification
• Hands-on experience with industry-standard tools such as Cadence Virtuoso (or equivalent)
• Solid understanding of DRC, LVS, ERC, and physical signoff methodologies

• 10 12 years of experience in advanced-node layout implementation (FinFET, GAA, or similar technologies)
• Deep expertise in layout techniques such as common-centroid, interdigitation, shielding, and isolation
• Strong understanding of signal integrity, power integrity, and thermal effects in high-speed designs
• Experience working on SerDes, PAM4, or other high-speed interface designs
• Familiarity with EM/IR analysis, parasitic extraction, and reliability considerations
• Experience with scripting (Python, Perl, or TCL) for automation
• Comfortable working in Linux-based environments
• Demonstrated technical leadership and ability to drive execution across global, cross-functional teams
• Strong communication, problem-solving, and collaboration skills
