High-speed Low-Power Interconnect Technology Sr. Engineer

Company: Qualcomm Technologies, Inc. Job Area: Engineering Group, Engineering Group > ASICS Engineering General Summary: We are seeking a highly skilled Senior Device Engineer with deep expertise in low‑power interconnects and SiPh/optical interfaces. This role requires close collaboration with internal design, CAD, yield, and test teams, as well as external foundries and test partners. You will develop and implement low‑power, high‑density interconnect technologies—electrical and optical—to support advanced memory ICs and chiplets for the AI era (training and inference). The ideal candidate has strong expertise in CMOS/photonic interconnect technologies, circuit design, and simulation, PIC simulation and optimization, PDK development, and tap‑out flows. Responsibilities: Low‑Power Interconnect Design Design and optimize low‑power chiplet‑to‑chiplet interconnects using copper (TSVs, micro‑bumps) and optical waveguides. Develop and simulate PIC components, including modulators, photodetectors, multiplexers, fiber‑to‑chip couplers, and lasers/uLED. Construct and validate optical link budgets, ensuring robust Tx/Rx signal integrity (IMDD/Coherent). FEM Simulation & AI‑Driven Optimization Perform optical/RF simulations using Ansys Lumerical (FDTD, MODE, INTERCONNECT), COMSOL, or similar tools. Build and apply AI‑based inverse design workflows to discover novel, high‑performance photonic or RF structures. Model and mitigate manufacturing‑induced variations and assess their impact on interconnect device performance for fab tape‑outs. Process, PDK, and Characterization Partner with test, yield, and design teams to address fab‑related issues for new optical/SiPh processes and products. Support technology benchmarking and model validation using test IP cores for PIC structures and interconnect Rx/Tx building blocks. Support end‑to‑end tape‑out activities including mask reviews, database preparation, and validation. Lead wafer‑and die‑level optical characterization including automated probe station measurements of bandwidth, insertion loss, and thermal behavior. Cross‑Functional Collaboration Interface with global CAD, design, SQE, YMT, package, and reliability teams to resolve issues effectively. Collaborate with external IP vendors, fabs, OSATs, and silicon/III‑V service partners to ensure timely execution. Minimum Qualifications: Bachelor's degree in Science, Engineering, or related field and 2+ years of ASIC design, verification, validation, integration, or related work experience. Master's degree in Science, Engineering, or related field and 1+ year of ASIC design, verification, validation, integration, or related work experience. PhD in Science, Engineering, or related field. Preferred Qualifications: Minimum 2 years of experience in silicon photonics, optics, high‑speed interconnects, or PIC design. Hands‑on experience with interconnect circuit design, PIC design/simulation, and PEX/EM tools (Cadence, ADS, Lumerical, COMSOL). Knowledge of digital/RF/MSA CMOS design flows is a plus. Experience with technology development, benchmarking, and model validation using test IP for RF/PIC/analog applications. Strong understanding of interconnect link‑budget calculations, optical communications, and AI‑driven simulation workflows. Excellent communication skills with demonstrated ability to meet deadlines and solve problems efficiently. Experience with hardware description languages such as Verilog or VHDL. Experience using statistical tools and scripting languages (Python, Tcl, JMP). Understanding of CMOS/SiPh process flows, including lithography, etch, and deposition. Knowledge of optical/SiPh process modules is a strong plus.
