Job Description
Cisco s Client Optics Group (COG) designs delivers the high-speed optical transceivers, and platforms that power Ciscos core data center networking solutions. We specialize in the design and integration of cutting-edge IM/DD optics and silicon photonic platforms that enable customers to deploy industry-leading optical technologies within data center with unprecedented speed, capacity, and reliability. Come join us and take part in shaping COG s ground-breaking optical solutions by designing, developing, and testing some of the most advanced pluggable, and Co-packaged Optics (CPO) being developed in the industry. You will work with Ciscos best-in-class Silicon Photonics team. Our team is responsible for driving the development and optimization of optical transceivers modules (800G,1.6T beyond) that seamlessly integrate with Ciscos routing, switching, and datacenter platforms, enabling customers to build scalable, high-performance networks that support emerging technologies including AI/ML workloads, and next-generation data center architectures. We seek an experienced High Speed AMS Design Engineer to lead full-chip electrical specifications and mixed-signal design for Ciscos silicon photonics driver integrated circuits supporting 100G/200G/400G per Lambda solutions. You will own high-speed datapath and low-speed control circuit design for receive and transmit paths in our next-generation silicon photonics modules. Your Impact As a High-Speed Analog/Mixed-Signal (AMS) Design Leader, you will play a pivotal role in shaping next-generation silicon photonics driver ICs. You will:
- Lead full-chip electrical architecture, specifications, and execution for high-speed silicon photonics driver ICs (100G/200G/400G per lambda)
- Own end-to-end mixed-signal design for both transmit and receive paths, including high-speed datapath and low-speed control circuits
- Design and optimize critical building blocks such as modulator drivers, TIAs, serializers, PLLs, and control loops
- Drive performance across power, speed, signal integrity, testability, and cost
- Partner cross-functionally with optical, system, and product teams to align design with real-world deployment requirements
- Define and execute verification and validation strategies from concept through production
- Lead silicon bring-up, debug, and lab validation resolving complex system-level challenges and improving yield
- Influence architecture decisions and contribute to next-gen product roadmaps
- Mentor engineers across analog, digital, and validation domains, fostering technical excellence and innovation
- Bachelor s + 12 years, Master s + 8 years, or PhD + 5 years of experience in high-speed analog/mixed-signal design
- Strong expertise in high-speed optical transceiver circuits (modulator drivers, TIAs, CDRs, PLLs, ADC/DAC)
- Proven experience leading designs through full tapeout cycles and delivering successful silicon
- Hands-on proficiency with industry tools such as Cadence Virtuoso, Spectre, Calibre, Verilog/SystemVerilog, or Verilog-AMS
- Experience in scripting and automation using Python or C
- Ability to make critical technical decisions in ambiguous, fast-paced environments
- 10 15 years of deep hands-on experience in analog/mixed-signal IC design
- Experience with silicon photonics driver ICs and direct-detect optical architectures
- Strong understanding of silicon photonics, optical subsystems, and industry standards (QSFP/QSFP-DD, IEEE 802.3)
- Expertise in high-speed PHYs and protocols (112G/224G PAM4 SerDes, Ethernet, UCIe, CDR systems, PLLs)
- Experience in design for testability (DFT) and developing test methodologies for large mixed-signal systems
- Hands-on lab experience with high-speed measurement equipment (BERTs, oscilloscopes, communication analyzers)
- Familiarity with SI/PI analysis, PCB/test fixture design, and optical component modeling (photodiodes, modulators, Verilog-A)
- Strong collaboration skills with the ability to work across global, cross-functional teams
