About the role
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, specializing in IM/DD optics and silicon photonic platforms for pluggable, Near Packaged Optics and Co-packaged Optics. The team develops and optimizes 800G, 1.6T and beyond optical transceivers and modules that integrate with Cisco's routing, switching, and datacenter platforms for AI/ML workloads and next-generation data center architectures. This role drives full-chip electrical specifications and mixed-signal design of high-speed datapath and low-speed control circuits for silicon photonics driver ICs supporting 100G/200G/400G per Lambda solutions.
What you will do
- Participate in analog/mixed-signal design for Cisco's next generation silicon photonics driver integrated circuits for 100G/200G/400G per Lambda solutions.
- Drive 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.
- Collaborate with architecture, digital, SI/PI and product teams on verification, design and testability strategies.
Skills used in this role
What the employer is looking for
- Bachelors + 7 years of related experience, or Masters + 4 years of related experience, or PhD + 1 years of high-speed AMS design experience
- Demonstrated knowldedge in high-speed optical transceiver design (modulator drivers, TIA, CDR, PLLs, ADC/DAC) and proficiency with industry standard tools (Cadence Virtuoso, Spectre, Caliber)
- Strong skills in device physics, & circuit operations
- Proficiency in Python or C for design automation, scripting, and analytical tools
Preferred qualifications
- Master’s or PhD degree in Electrical Engineering
- 6-8 years of hands-on analog/mixed signal circuit design experience
- Experience with silicon photonics driver ICs and direct-detect optical module architectures
- Good understanding of silicon photonics, optical subsystems
- Expertise in one or more high-speed PHYs, protocols and subsystems (SerDes 112Gbps/224Gbps PAM4, Ethernet, UCIE, clock and data recovery systems, PLLs, ADC/DAC circuits)
- Hands-on experience with lab instrumentation (digital communication analyzers, real-time scopes, BERTs), SI/PI and test fixture/PCB
- Familiarity with Verilog-A modeling for AMS simulations
- Strong collaborator, team player with ability to work across teams in multiple sites
Benefits and support
- Compensation and benefits are detailed in the job posting
