Memory & Data-Movement / Chiplet Architect (IRT712ST RM 4408)

Position: Memory & Data-Movement / Chiplet Architect (IRT712ST RM 4408)

Position Summary
Develop models and architecture studies for HBM, DDR, CXL memory, and system-level data movement in AI infrastructure.

Work mode : Hybrid

Education : B.E. / B.Tech / M.E. / M.Tech in Electronics, Electrical, Computer Engineering, or related discipline.

Key Responsibilities

• Memory / Data-Movement Modelling: Develop functional/ performance models for HBM/DDR/memory subsystems; model memory bandwidth, latency, and access patterns; model DMA and high-volume data movement; analyze buffering, queues, and traffic patterns; evaluate CXLbased memory architectures.
• Multi-Chiplet / Multi-XPU Scalability: Analyze memory scaling with multiple XPUs/chiplets, study aggregate bandwidth requirements, and identify memory bottlenecks in multi-XPU configurations.
• System Performance & Architecture Exploration: Perform memory architecture trade-offs, evaluate bandwidth vs. latency vs. capacity, and correlate memory behavior with AI workload requirements.

Required Technical Skills

• HBM / DDR.
• 7–12+ years of semiconductor/system architecture experience.
• Memory controllers.
• Data movement / DMA.
• SystemC/TLM.
• C++ / Python.
• AI/HPC system architecture.

Preferred Skills

• Chiplet architecture, UCIe, PCIe.
• Cache/coherency.
• HBM2E / HBM3 / HBM3E.
• AI accelerator architecture.

Project Experience : Hands-on memory/data-movement architecture or modelling work on HBM, DDR, or CXL-based memory systems.

Soft Skills

• Strong quantitative reasoning across bandwidth, latency, and capacity trade-offs.
• Ability to correlate memory-subsystem behavior with AI workload requirements for non-memoryspecialist stakeholders.

Good to Have

• Direct HBM2E/HBM3/HBM3E architecture or modelling experience.
• Exposure to cache/coherency design in a multi-chiplet system.

Expected Deliverables

• Functional/performance models for HBM/DDR/CXL memory subsystems.
• Memory scaling analysis across multi-XPU/chiplet configurations.
• Memory architecture trade-off studies (bandwidth vs. latency vs. capacity).

Growth Path : Progress into Principal Memory Architect or Memory Subsystem Practice Lead roles.
