## Description

Cisco’s Silicon One Optics Group (S1O) designs and delivers high-speed optical transceivers and platforms that power Cisco's core data center networking solutions.

We seek an experienced High Speed AMS Design Engineer to lead full-chip electrical specifications and mixed-signal design for Cisco's silicon photonics driver integrated circuits supporting 100G/200G/400G per Lambda solutions.

**Your Impact**

- Provide technical leadership in analog/mixed-signal design for Cisco's next-generation silicon photonics driver integrated circuits for 100G/200G/400G per Lambda solutions.

- Lead full-chip electrical specifications, circuit design, and verification test plans from concept through production, coordinating across electrical, optical, and product teams.

- Author mixed-signal datapath designs including photonics modulator drivers, serializers, PLLs, TIAs, and control circuits while optimizing for power, performance, testability, and cost.

- Debug complex silicon and system-level issues during bring-up and lab validation phases, driving yield enhancements and failure analysis.

- Mentor and guide analog, digital, and validation engineers while collaborating with architecture and product teams on verification and testability strategies.

**Minimum Qualifications**

- Bachelors + 12 years of related experience, or Masters + 8 years of related experience, or PhD + 5 years of high-speed AMS design experience.

- Demonstrated expertise in high-speed optical transceiver design (modulator drivers, TIA, CDR, PLLs, ADC/DAC) and proficiency with industry-standard tools (Cadence Virtuoso, Spectre, Caliber, SystemVerilog, Verilog-AMS).

- Proven ability to lead design teams through full tapeout cycle, making critical decisions with limited data and delivering successful silicon products.

- Proficiency in Python or C for design automation, scripting, and analytical tools.

**Preferred Qualifications**

- 10-15 years of hands-on analog/mixed signal circuit design experience.

- Experience with silicon photonics driver ICs and direct-detect optical module architectures.

- Strong understanding of silicon photonics, optical subsystems, MSA standards (QSFP/QSFP-DD), and IEEE 802.3 specifications.

- Expertise in multiple high-speed PHYs, protocols, and subsystems (SerDes 112Gbps/224Gbps PAM4, Ethernet, UCIE, clock and data recovery systems, PLLs, ADC/DAC circuits).

- Demonstrated experience in design for testability (DFT) and test methodology development for large mixed-signal designs.

- Hands-on experience with lab instrumentation (digital communication analyzers, real-time scopes, BERTs), SI/PI, and test fixture/PCB.

- Familiarity with optical sub-component models (photodiodes, modulators) and Verilog-A modeling for AMS simulations.

- Strong collaborator, team player with the ability to work across teams in multiple sites.
