Job Overview
At Arm, we are shaping the future of computing for cloud and AI infrastructure. Our hyperscale partners rely on Arm technology to deliver performance and efficiency on a meaningful scale.
We seek a Principal Field Applications Engineer (FAE) to guide critical technical teamworks with Tier 1 hyperscale customers—from initial architectural review to product rollout. This is a technically intensive, customer-facing position. In this impactful role, you will steer infrastructure build decisions, coordinate customer requirements alongside Arm’s roadmap, and hasten the adoption of Arm-based platforms.
This role focuses on silicon at the architectural level. You will guide CPU configuration, coherency fabric design, memory subsystem architecture, and large-scale system integration. Your work begins at early definition and continues through silicon bring-up to production.
You will work closely with Account, Engineering, and Product teams to ensure technical alignment and long-term customer success. This role requires deep system expertise, strong communication skills, and the ability to operate independently in dynamic environments. Approximately 8% travel is expected, including occasional UK trips.
Key Responsibilities
- Lead architecture-level collaborations with hyperscaler customers throughout the entire silicon lifecycle, serving as their dependable technical advisor and ensuring system builds align with Arm’s strategic direction.
- Find opportunities to implement Arm technology in partner designs and provide both pre-sales and post-sales technical leadership.
- Influence adoption of Arm Cloud AI solutions; including Arm CSS (Neoverse CPU configuration, core scaling, cache hierarchy, and coherency fabric topology, such as CMN).
- Advise on memory subsystem design (DDR5, HBM, NUMA scaling) and bandwidth/latency trade-offs.
- Lead PCIe Gen5/6 and CXL integration engagements, including coherent memory expansion strategies.
- Lead accelerator and heterogeneous compute integration within server-class SoCs.
- Support partners using pre-silicon performance models to identify architectural bottlenecks prior to tape-out.
- Collaborate with customers to optimize workloads, including cloud-native applications, HPC, AI/ML, and enterprise systems.
- Stay informed on trends in cloud infrastructure, systems architecture, and modern software stacks.
- Anticipate technical risks, handle partner concerns, and ensure timely issue resolution.
- Communicate architectural concepts effectively to audiences with technical and executive backgrounds.
- Drive technical alignment between customer silicon teams and Arm engineering.
- Provide structured field feedback to influence product direction and driven positioning decisions.
- Promote consensus on firmware requirements through leading dialogues between customers and internal engineering departments, ensuring customer needs are thoroughly recorded.
- Own technical customer concerns by coordinating issue triage and resolution across customers, internal engineering teams, and ecosystem partners, driving issues to closure with clear communication and accountability.
Who You Are
- Deeply experienced infrastructure technologist with demonstrated success driving adoption of sophisticated silicon platforms at hyperscale customers.
- Comfortable operating across abstraction layers — from high-level architecture strategy to low-level technical details.
- Demonstrated skill in assisting customers during the assessment, incorporation, and start-up and production implementation of sophisticated infrastructure technologies.
- Clear, persuasive communicator who simplifies sophisticated architectural concepts into actionable recommendations for both technical and executive audiences.
- Strategic advisor capable of influencing critical technical decisions in high-visibility, multi-company engagements.
- Self-directed, adaptable, and credible in multifaceted customer environments.
Required Qualifications
- Bachelor’s degree or equivalent experience in Electrical Engineering, Computer Engineering, Computer Science, or a comparable field.
- confirmed experience in server SoC architecture, silicon integration, system engineering, or applications engineering.
- Strong understanding of server-class CPU architecture and cache/memory hierarchy behavior.
- Experience with coherency protocols (such as CHI or similar expertise) and scalable interconnect fabrics.
- Solid knowledge of DDR5/HBM subsystems and NUMA architecture.
- Background in integrating PCIe and knowledge of CXL or comparable expertise in data center settings.
- Exposure to pre-silicon modeling and/or post-silicon bring-up and validation.
- Experience working with hyperscale or large cloud silicon programs.
Preferred Qualifications
- Master’s degree or comparable experience in EE, CE, CS, or a related field.
- Experience with Arm CSS, Neoverse CPUs, CMN interconnect and System IP.
- Experience with chiplet or multi-die server architectures.
- Experience in integrating AI accelerators or heterogeneous computing systems.
- Track record of influencing architecture decisions in production silicon programs.
