Compute Subsystem Architect

MediaTek is seeking a Compute Subsystem Architect to define and build capability in this space ahead of product commitment. The role covers the full Neoverse Compute Subsystem scope: core configuration, CMN topology and parameterization, cache/SLC architecture, and CHI coherency behavior. The role also provides architectural guidance on chiplet and 3D‑IC partitioning trade‑offs, collaborating with dedicated packaging and interconnect teams on interface definitions. Responsibilities Architect compute subsystems (CPU cluster, L2/L3/SLC cache, coherent mesh fabric) for next‑generation ASIC and advanced Arm computing platform products. Own CMN topology recommendations: mesh dimension, HN‑F/SN‑F/RN‑F placement, SLC distribution, snoop filter policy, and QoS parameters. Build CPU subsystem performance models to quantify many‑core scaling: latency, bandwidth‑per‑core, and mesh congestion under AI‑era workload traffic patterns. Drive technology readiness: track Arm Neoverse CSS/CMN roadmap, identify IP gaps, and lead technical engagement with Arm on architecture and multi‑die scope. Evaluate architectural implications of 3D‑IC and chiplet splits on CMN topology, CHI credit return, and snoop timing; hand off quantified constraints to packaging and physical teams; co‑design while maintaining focus on computing architecture. Align design with potential product landing vehicles including custom ASIC solutions and advanced Arm platforms (including future CPU Dielet configurations). Prepare architecture specifications and technical documents; present trade‑offs to engineering leadership and executives. Qualifications Deep expertise in Arm CMN‑series coherent mesh networks: topology sizing, HN/SN/RN placement, SLC optimization, QoS. Arm Neoverse CSS experience strongly preferred (required). Proficiency in AMBA CHI protocol: transaction types, snoop behavior, credit flow, and debug mechanisms (required). Experience architecting for many‑core scaling (32+ cores): coherency overhead, cache/fabric co‑optimization, tail‑latency analysis (required). Familiarity with CXL Type‑1/2/3 and server‑class RAS architecture (desired). Excellent communication skills; ability to produce high‑quality architecture documents and present complex trade‑offs to both engineers and executives. Educational background: MS in Electrical Engineering, Computer Engineering, Computer Science. Minimum 10 years of relevant industry experience. Architecture definition and technology readiness for Neoverse CSS‑based compute subsystems: CPU cluster, CMN, cache/SLC, and CHI coherency. Architectural interface ownership for chiplet/3D‑IC configurations; packaging and D2D implementation handled by dedicated functional teams. Opportunity to shape MediaTek’s advanced computing platform strategy and data center CPU roadmap from the ground up. Compensation & Benefits Salary range: $211,000–$356,000. Employee may be eligible for performance bonus, short and long term incentive programs. Actual total compensation will be dependent upon the individual’s skills, experience and qualifications. MediaTek provides a variety of benefits including comprehensive health insurance coverage, life and disability insurance, savings plan, company paid holidays, sick leave, vacation time, parental leave, 401(k) and more.
