Sr Principal TIA Designer

Join Nokia's advanced photonics and semiconductor design team, developing next-generation analog ICs for high-speed optical communication systems. In this role, you will lead the design of multi-tens of GHz Transimpedance Amplifiers (TIAs) for coherent long-haul, metro, and PAM4 data center applications, leveraging cutting-edge SiGe BiCMOS and CMOS technologies. You'll play a key role in delivering innovative solutions that enable faster, more efficient data transmission across data centers, telecommunications networks, and emerging AI-driven infrastructure. NION2026 Extensive experience designing high-speed TIAs for coherent optical communication systems and/or PAM4 data center transceivers. Strong expertise in analog and mixed-signal IC design using SiGe BiCMOS and CMOS technologies. Deep understanding of transistor-level circuit design, device physics, noise analysis, and feedback/control loop stability. Proven experience in one or more of the following areas: Optical receiver front-end design AGC loop implementation CTLE design High-precision analog circuits (bandgaps, regulators, ADC/DAC interfaces) Package and system-level integration Proficiency with industry-standard EDA tools, custom analog layout techniques, and electromagnetic (EM) simulation tools. Demonstrated success delivering silicon from concept through production. Hands-on experience with lab measurement, debugging, and performance validation of high-speed ICs. Strong leadership, problem-solving, communication, and collaboration skills. Ability to work effectively in a fast-paced, multidisciplinary global engineering environment.
