This is a hybrid role with four days per week at Cisco’s Yerevan office.

Meet the Team

Join the Silicon One Team at Cisco, a group at the forefront of developing Cisco's groundbreaking silicon architecture. We are a collaborative unit focused on pushing the boundaries of ASIC design for advanced process nodes. As part of our team, you will contribute to defining innovative Physical Design methodologies and creating robust flows essential for developing our complex chips. You will also have the opportunity to work hands-on with the Physical Design of intricate chip partitions.

Your Impact

This role as a Static Timing Analysis (STA) CAD/Methodology Engineer on Cisco’s Silicon One Engineering team offers a key opportunity to enable the next generation of high-performance networking SoCs and ASICs. You will lead the development of scalable STA flows and automation, enhancing the efficiency and quality of design processes. Working at the intersection of design, methodology, and infrastructure, you will help establish best practices and drive innovation within a leading silicon organization.

• Architect, develop, and maintain static timing analysis (STA) methodologies and flows to support full-chip and hierarchical signoff for high-speed networking ASICs.

• Support timing closure for SoCs with complex clocking structures, high-speed interfaces, and large-scale integration.

• Develop robust SDC management, checking, and validation infrastructure across multi-mode, multi-corner (MMMC) scenarios.

• Build and optimize automation scripts and infrastructure (TCL, Python, Makefiles, etc.) to scale timing flows for enterprise-level SoC programs.

• Collaborate with RTL design, DFT, P&R, and signoff teams to align on timing methodologies and resolve critical timing issues.

• Work with EDA vendors to drive tool evaluations, enhancements, and roadmap discussions.

• Drive flow standardization across business units and participate in timing methodology governance across global CAD teams.

Minimum Qualifications

• B.S./M.S. in Electrical Engineering, Computer Engineering, or related field.

• 6+ years of experience in ASIC/SoC timing analysis, CAD flow development, or physical design methodology.

• Expertise in STA fundamentals, including setup/hold, skew, OCV/AOCV/POCV, CRPR, and noise analysis.

• Proficiency with industry-standard tools such as Synopsys PrimeTime, Cadence Tempus, or equivalent.

• Strong scripting experience in TCL, Python, and automation frameworks.

• First-hand experience with timing constraint (SDC) creation, management, and validation.

• Solid understanding of physical implementation flows (synthesis, floorplanning, P&R, timing ECO).

• Experience with large-scale SoC programs and hierarchical timing signoff flows.

Preferred Qualifications

• Familiarity with networking ASIC design challenges (e.g., low latency, high-throughput clocking, SerDes, packet processors) is a strong plus.

• Strong communicator and team player, able to work across geographically distributed teams.

• Exposure to networking ASIC architectures, high-speed interface timing, and power-aware timing flows.

• Experience with liberty modeling, timing model generation, and correlation to silicon.

• Familiarity with version control systems (e.g., Git/Perforce), and job schedulers (LSF/SLURM).

• Prior experience in a large enterprise engineering organization or global silicon team is a plus.
