Senior System Architect – Ethernet PHY & High-Speed Interconnect (m/f/d)

Job description

Huawei Heisenberg Research Center (Munich) drives advanced research and innovation in next-generation communication technologies, combining system architecture, modeling, and strategic engineering to shape future products and contribute to industry direction and standards. The Applied Network Technology Lab (ANTL) in Munich is expanding its research activities in next-generation Ethernet and high-speed interconnect technologies for data center networks. A key focus area is the physical layer (PHY), where increasing data rates introduce new challenges in signal integrity, non-linearities, and system-level optimization. We are looking for an experienced architect who can bridge deep technical analysis with long-term technology strategy, translating complex system behavior into scalable architectural solutions that will influence future products and industry standards. This is a highly influential role operating at the intersection of system architecture, advanced modelling and standards development. Join the ANTL Ethernet Team as a Senior System Architect (m/f/d) Your mission Define and and employ end-to-end PHY system models for architecture decision, covering channel behavior, TX/RX impairments, data converter constraints and associated non-idealities. Lead architecture trade-off studies across performance, power, bandwidth, BER, latency and implementation feasibility. Evaluate equalization and signal processing techniques under realistic system limitations and hardware impairments. Translate complex simulation results, impairment analysis and implementation constraints into clear, data-driven architectural recommendations and engineering insights. Define system-level constraints, performance budgets and identify optimization opportunities for future Ethernet PHY architectures. Monitor emerging Ethernet technologies and analyze standards, including IEEE 802.3, UEC, OIF and MSA activities, to identify opportunities for innovation. Shape technical positions and contribute to industry standards discussions through robust technical analysis. Provide technical leadership, architecture guidance and mentorship to engineers across multidisciplinary teams. Collaborate with universities, research institutes and external partners to help shape future PHY concepts. Your profile/areas of expertise Essential Master's degree and/or PhD in Electrical Engineering, Electronic Engineering, Computer Science or a related discipline. Strong experience with high-speed PHY, SerDes system or wireline communication system architecture. Solid understanding of Ethernet PHY architecture, including channel modelling, equalization, jitter, noise analysis and system-level data converter impact on link performance. Proficiency in Python, MATLAB or similar system-level simulation environments for architecture exploration and trade-off analysis. Ability to abstract complex physical phenomena into accurate and actionable system models and architecture trade-offs. Proven ability to make architecture decisions under technical uncertainty and clearly communicate assumptions, risks and trade-offs. Excellent communication and collaboration skills in international environments. Full professional proficiency in English. Preferred Experience with ≥100Gb/s per lane systems. Familiarity with IEEE Ethernet standards activities, UEC, OIF and MSA ecosystems, including how standards decisions influence PHY architecture choices. Experience contributing to standards discussions, technical papers or industry forums. German and/or Chinese language skills. Some international travel will be required as part of the role.
