About the role

We are building the next generation of large-scale AI systems that power training and inference workloads at unprecedented scale and efficiency. You will design and develop high-performance distributed software that orchestrates massive compute and data pipelines across heterogeneous clusters, pushing the limits of concurrency, throughput, and scalability for models at massive scale.

Responsibilities

  • Design and implement distributed runtime components to efficiently manage large-scale execution workloads.
  • Develop and optimize high-performance data and communication pipelines that fully utilize CPU, memory, storage, and network resources.
  • Enable scalable execution across multiple compute nodes, ensuring high concurrency and minimal bottlenecks.
  • Collaborate closely with ML and compiler teams to integrate new model architectures, training regimes, and hardware-specific optimizations.
  • Diagnose and resolve complex performance issues across the software stack using profiling and instrumentation tools.
  • Contribute to overall system design, architecture reviews, and roadmap planning for large-scale AI workloads.

Qualifications

  • 3+ years of experience developing high-performance or distributed system software.
  • Strong programming skills in C/C++, with expertise in multi-threading, memory management, and performance optimization.
  • Experience with distributed systems, networking, or inter-process communication.
  • Solid understanding of data structures, concurrency, and system-level resource management (CPU, I/O, and memory).
  • Proven ability to debug, profile, and optimize code across scales—from threads to clusters.
  • Bachelor’s, Master’s, or equivalent experience in Computer Science, Electrical Engineering, or related field.
