ASIC Design Technical Leader – Design & Timing Constraints Focus

The application window is expected to close on: US 01/25/2026. This position will be onsite in San Jose 5 days per week. Meet the Team Join the Cisco Silicon One team in developing a unified silicon architecture for web scale and service provider networks. Cisco’s silicon team offers a unique experience for ASIC engineers, combining the resources and stability of a large, multi-geography organization with the agility and growth opportunities of a smaller, startup-style team. You’ll collaborate with exceptional talent with deep ASIC design and development expertise. As part of a systems company, you’ll also have the opportunity to partner with other ASIC teams throughout the full lifecycle, from concept to first customer shipments. Your Impact You are a diligent Design/SDC Engineer with strong analytical skills and a deep understanding of timing constraints, including clock groups, exceptions, and clock exclusivity. Proficient in industry-standard SDC/STA tools and scripting for automation, you excel at identifying and resolving timing issues across all design levels. You will collaborate with Front-end and Back-end teams to understand chip architecture and guide them in refining design and timing constraints for seamless physical design closure. As part of this team, you’ll contribute to developing next-generation networking chips. Responsibilities include: Being a member of design team who oversees fullchip SDCs and works with physical design and DFT teams to close fullchip timing in multiple timing modes. Option to also do block level RTL design or block or top-level IP integration. Helping develop efficient methodology to promote block level SDCs to fullchip, and to bring fullchip SDC changes back to block level. Helping develop and apply methodology to ensure correctness and quality of SDCs as early as possible in design cycle. Reviewing block level SDCs and clocking diagrams and mentor other RTL design owners on SDC development. Creating fullchip clocking diagrams and related documentation. Minimum Qualifications: Bachelor’s Degree in Electrical or Computer Engineering with 8+ years of ASIC or related experience or Master’s Degree in Electrical or Computer Engineering with 6+ years of ASIC or related experience. Experience with block/full chip SDC development in functional and test modes. Experience in Static Timing Analysis and prior working experience with STA tools like PrimeTime/Tempus. Understanding of related digital design concepts (eg. clocking and async boundaries). Experience with synthesis tools (eg. Synopsys DC/DCG/FC), Verilog/System Verilog programming. Preferred Qualifications: Experience with constraint analyzer tools such as TCM (Timing Constraint Manager from Synopsys) and CCD (Conformal Constraint Designer from Cadence). Experience with Spyglass CDC and glitch analysis. Experience using Formal Verification: Synopsys Formality and Cadence LEC. Experience with scripting languages such as Python, Perl, or TCL. .
