Your Team, Your Impact
Marvell is a global leader in high-performance silicon and AI infrastructure, powering the world's most advanced datacenters, cloud platforms, 5G networks, and AI/ML workloads. Our innovations drive next-generation computing, networking, and storage, enabling breakthrough performance, scalability, and efficiency for the most demanding applications.

This team at Marvell develops Murals, a next-generation AI/ML infrastructure simulation and design platform that enables in-depth analysis and optimization of large-scale training and inference workloads. Leveraging trace-driven simulation, performance modeling, and hardware/software co-design, the team helps shape scalable and resilient solutions for advanced workloads such as LLMs, DLRMs, GenAI, and GNNs.

Working closely with system architects, hardware designers, and ML practitioners, the team explores innovative ways to optimize compute, memory, and networking subsystems across complex datacenter environments.

What You Can Expect

• Simulation & Modeling – Implement workflows to study AI/ML workloads using trace-driven and analytical models.
• Performance Analysis – Profile and analyze system bottlenecks across compute, memory, and network layers.
• Networking Studies – Evaluate collective communication performance (all-reduce, all-to-all, reduce-scatter) across different topologies and fabrics.
• Tooling & Automation – Develop utilities for trace generation, merging, conversion, and visualization.
• Prototype & Validation – Test distributed training and inference pipelines in simulated and real environments.
• Hardware/Software Co-Design – Collaborate on emerging technologies (CXL, DPUs, NVLink, PCIe, UET/UEC, in-network compute).
• Scaling Studies – Conduct performance projections and trade-off studies for next-gen AI infrastructure.
• Knowledge Sharing – Document workflows, publish internal reports, and drive peer learning.

What We're Looking For

• Bachelor's, Master's, or PhD in Computer Science, Electrical Engineering, or related field with 4–12 years of relevant professional experience.
• Strong foundation in computer architecture, distributed systems, AI/ML, and operating systems.
• Solid networking fundamentals including TCP/IP, RDMA, RoCE, UET/UEC, and switching/routing.
• Experience with simulation frameworks (e.g., Astra-Sim, Chakra, gem5, SST, NS-3).
• Hands-on with PyTorch/TensorFlow and distributed training frameworks (DDP, Horovod, DeepSpeed).
• Strong programming skills in Python, C++, and scripting for automation.
• Familiarity with interconnect and memory technologies (CXL, PCIe, NVLink, UAL).
• Experience with profiling, telemetry, observability, and debugging tools.
• Knowledge of collective communication algorithms and topology-aware scheduling.
• Exposure to AI accelerators, memory disaggregation, DPUs, and custom silicon.
• Familiarity with visualization tools (Perfetto, Chrome Tracing, Chakra Timeline, Flamegraphs).
• Experience with large-scale AI training pipelines and scaling studies.
• Interest in energy/performance trade-offs and resilience techniques.
