Job description

Job Description

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.

Requirements and 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.
• Scope: Architecture definition and technology readiness for Neoverse CSS-based compute subsystems: CPU cluster, CMN, cache/SLC, and CHI coherency.
• Scope: Architectural interface ownership for chiplet/3D-IC configurations; packaging and D2D implementation handled by dedicated functional teams.
• Scope: Opportunity to shape MediaTek's advanced computing platform strategy and data center CPU roadmap from the ground up.

Compensation and 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.

In addition, 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, 401K and more.
