Silicon Photonics Design Engineer Technical Lead- (Hybrid)

The application window closes on 07/25/2026. This hybrid role requires three days per week at Cisco’s Carlsbad, Allentown, or Santa Monica office. Meet the Team The Common Hardware Group (CHG) creates innovative hardware platforms central to the AI era, powering Cisco’s core Switching, Routing, and Wireless products. Our innovations in silicon, optics, and hardware platforms—like Silicon One—are shaping the technology industry. We are a global team of creative experts, pushing boundaries to power the future of the digital world. Your Impact As a Silicon Photonics Design Engineer Technical Lead, you will design, develop, and qualify integrated optical devices used in Cisco silicon photonics transceivers. Work on integrated optical devices with a team to enable next‑generation Cisco optical transceiver products. Develop modulators and photodetectors through device design, layout of test and characterization structures, testing (including high‑speed), and reliability qualification. Interact with the foundry and its engineers to optimize manufacturing process and select process parameters. Interface with product team IC designers to deliver device models and optimize performance parameters of optoelectronic devices to match with drivers and TIAs. Minimum Qualifications Bachelor’s degree in Optics, Electrical Engineering, Physics, or a related field and 8+ years of engineering experience. Experience designing passive and active silicon photonics components (e.g., grating couplers, photodetectors, modulators, filters) or subsystems that use them. Experience using software modeling tools such as Ansys/Lumerical, Silvaco, or Photon Design. Experience using CAD layout tools such as Cadence Virtuoso, kLayout, etc. Preferred Qualifications Master’s degree in Optics, Electrical Engineering, Physics, or a related field and 6+ years of engineering experience, or PhD in Optics, Electrical Engineering, Physics, or a related field and 3+ years of experience. Experience with optical test equipment (e.g., tunable lasers, detectors, OSA, VNA) and microwave measurement techniques, as well as statistical analysis tools (e.g., JMP). Experience designing integrated electronic circuits that interface with active silicon photonics components (e.g., TIAs, modulator drivers). #J-18808-Ljbffr
