• Excellent communication and collaboration skills across engineering organizations.

• Passion for building foundational technologies that enable the next generation of AI workloads.

Responsibilities

Key Responsibilities

• Architect and develop high-performance networking software for large-scale AI and HPC environments.

• Design and implement RDMA-based services and infrastructure that enable low-latency, high-throughput communication across GPU clusters.

• Drive the evolution of collective communication frameworks and transport layers used by distributed AI training and inference workloads.

• Develop congestion management, traffic engineering, load balancing, and resiliency mechanisms for large-scale RDMA networks.

• Optimize end-to-end communication performance across networking, GPU, and software stacks.

• Collaborate with hardware, networking, distributed systems, and AI platform teams to deliver scalable infrastructure solutions.

• Lead performance analysis, bottleneck identification, and system-wide optimization efforts.

• Define architecture and technical direction for networking platforms supporting next-generation AI workloads.

• Build observability, monitoring, telemetry, and debugging capabilities for large-scale distributed systems.

• Drive reliability, fault tolerance, and recovery mechanisms for mission-critical AI infrastructure.

• Mentor engineers across the organization and provide technical leadership on complex cross-functional initiatives.

• Influence engineering best practices, architecture reviews, and long-term technology strategy.

Minimum Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or related field; advanced degree preferred.

• 10+ years of software engineering experience building distributed systems, networking software, or infrastructure platforms.

• Deep expertise in RDMA technologies including RoCE, InfiniBand, or equivalent high-performance networking technologies.

• Strong experience developing networking software in C/C++.

• Experience designing and optimizing distributed communication frameworks and transport protocols.

• Solid understanding of operating systems, networking stacks, memory management, and performance optimization.

• Experience troubleshooting and optimizing large-scale production systems.

• Demonstrated technical leadership driving architecture and execution across multiple teams.

• Strong knowledge of Linux systems and low-level systems programming.

Preferred Qualifications

• Experience with collective communication libraries such as NCCL, RCCL, MPI, UCC, UCX, XCCL, or similar technologies.

• Experience building AI infrastructure supporting distributed training and inference workloads.

• Expertise in GPU networking technologies including GPUDirect RDMA and GPU-aware communication stacks.

• Experience with congestion management, adaptive routing, traffic shaping, and network resiliency mechanisms.

• Familiarity with large-scale GPU clusters consisting of hundreds to thousands of accelerators.

• Experience developing services and platforms operating directly over RDMA transports.

• Knowledge of distributed training frameworks such as PyTorch, DeepSpeed, Megatron-LM, TensorFlow, or JAX.

• Experience with cloud infrastructure and large-scale production service deployment.

• Familiarity with Kubernetes, containerized environments, and cloud-native infrastructure.

• Experience leading architecture for highly available and performance-critical systems.
