TL;DR

As a Principal Field Applications Engineer (FAE) at Arm, you will join the Cloud and AI Infrastructure team to guide Tier 1 hyperscale customers through architectural reviews and product rollouts. Your day-to-day involves steering infrastructure build decisions, coordinating customer requirements with Arm’s roadmap, and accelerating the adoption of Arm-based platforms. Key responsibilities include advising on CPU configuration, coherency fabric design, memory subsystem architecture, and large-scale system integration. You will work closely with engineering teams to ensure technical alignment and long-term success, requiring expertise in server SoC architecture, cache/memory hierarchy behavior, and scalable interconnect fabrics like CHI. Strong knowledge of DDR5/HBM subsystems, PCIe Gen5/6, and CXL is essential, along with experience in pre-silicon modeling and post-silicon validation.
