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 provides a unique experience for ASIC engineers by combining the resources offered by a large multi-geography silicon organization and a large campus (with onsite gym, healthcare, and café, social interest groups, and philanthropy), with the startup culture and breadth of growth opportunities that working in a smaller ASIC team can provide.

Your Impact

• Own and develop full-chip timing constraints (SDC) across functional and test modes for complex networking SoCs.
• Drive Static Timing Analysis (STA) and partner with RTL, physical design, and DFT teams to resolve timing issues across the design hierarchy.
• Partner with RTL designers to achieve timing convergence through constraint development and timing-driven RTL improvements.
• Define and maintain clocking architectures and constraint models, including clock groups, timing exceptions, and clock exclusivity.
• Integrate and validate timing constraints from third-party IP vendors within the full-chip SoC timing environment.
• Develop and review block-level SDCs and clocking architectures, ensuring constraint correctness and alignment across the design hierarchy.
• Contribute to timing closure and silicon readiness across multiple modes, corners, and operating conditions.

Minimum Qualifications

• Bachelor’s degree in Electrical or Computer engineering and 7+ years of ASIC experience, or Master’s degree in Electrical Engineering or Computer Engineering and 4+ years of ASIC experience, or PhD in Electrical Engineering or Computer Engineering +1 years of ASIC experience.
• Experience developing block-level and full-chip SDC constraints for complex SoC designs.
• Expertise in Static Timing Analysis (STA) using tools such as Synopsys PrimeTime or Cadence Tempus.
• Experience writing timing constraints for complex networking SoCs and ARM CPU subsystems.
• Experience integrating third-party IP timing constraints into full-chip SDC environments.
• Understanding with RTL design and synthesis, with the ability to analyze RTL structures and guide timing-driven design improvements.

Preferred Qualifications

• Experience developing constraints for large SoCs with multiple clock domains and complex clocking architectures.
• Ability to analyze RTL structures and recommend timing-driven micro-architectural improvements.
• Expertise with constraint analysis tools (Synopsys TCM, Cadence CCD) and CDC analysis tools (SpyGlass CDC).
• Proficiency in engineering scripting and automation (Python, Perl, TCL).

U.S. employees are eligible for paid time away as described below, subject to Cisco’s policies:

• 10 paid holidays per full calendar year, plus 1 floating holiday for non-exempt employees
• 1 paid day off for employee’s birthday, paid year-end holiday shutdown, and 4 paid days off for personal wellness determined by Cisco
• Non-exempt employees** receive 16 days of paid vacation time per full calendar year, accrued at rate of 4.92 hours per pay period for full-time employees
• Exempt employees participate in Cisco’s flexible vacation time off program, which has no defined limit on how much vacation time eligible employees may use (subject to availability and some business limitations)
• 80 hours of sick time off provided on hire date and each January 1st thereafter, and up to 80 hours of unused sick time carried forward from one calendar year to the next
• Additional paid time away may be requested to deal with critical or emergency issues for family members
• Optional 10 paid days per full calendar year to volunteer

For non-sales roles, employees are also eligible to earn annual bonuses subject to Cisco’s policies.

Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components, subject to the applicable Cisco plan. For quota-based incentive pay, Cisco typically pays as follows:

• .75% of incentive target for each 1% of revenue attainment up to 50% of quota;
• 1.5% of incentive target for each 1% of attainment between 50% and 75%;
• 1% of incentive target for each 1% of attainment between 75% and 100%; and
• Once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.

For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay 0% up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.

The applicable full salary ranges for this position, by specific state, are listed below:

New York City Metro Area:
