• System-Level Validation: Define and execute comprehensive design verification and validation (DVT) strategies, ensuring adherence to rigorous regulatory and performance specifications.
• Advanced Troubleshooting: Serve as the primary technical authority for complex root cause analysis of hardware issues, including signal integrity, power distribution, and mechanical integration.
• Strategic Collaboration: Act as a key technical liaison between hardware, software, BIOS, and manufacturing teams. Provide expert guidance to resolve cross-functional bottlenecks.
• Process & Quality: Drive continuous improvement in design methodologies, maintain high-quality technical documentation, and conduct rigorous design reviews to mitigate risk.
• Mentorship: Provide technical guidance and mentorship to junior engineering staff, fostering a culture of innovation and engineering excellence.
• Integrate AI-driven design, simulation, and diagnostic tools to streamline design cycles, enhance predictive quality analysis, and improve overall operational efficiency

Minimum Qualifications:

• 4+ years of experience with a Masters’ degree or 7+ years of experience with a Bachelors’ degree. Experience expected to be in hardware design.
• Experience taking complex hardware products from concept to production.
• Experience with industry-standard design suites, such as Cadence Allegro/Concept, Mentor Graphics Xpedition, etc.

Preferred Qualifications:

• Architectural Expertise: Deep proficiency in board design leveraging x86, ARM, and high-performance FPGA/SoC architectures.
• High-Speed Design: Expert-level knowledge of high-speed interface bus design (PCIe Gen 4/5, DDR5, PAM4) and high-speed Ethernet (100G/400G).
• Board-Mounted Power Design (Bonus): Demonstrated expertise in designing robust power delivery networks (PDN). Proficiency in selecting and implementing DC-DC converters, LDOs, and managing power sequencing for high-current, low-voltage processors, FPGAs, and ASICs.
• Signal & Power Integrity: Advanced capability in modeling and mitigating signal integrity and power distribution challenges in dense, high-speed systems.
• Firmware/RTL Interaction: Strong understanding of RTL design (Verilog/System-Verilog) and its interaction with hardware/BIOS.
• Communication: Exceptional ability to communicate complex technical concepts to both technical and non-technical stakeholders.

• 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.
