Sr Software Development Engineer, Neuron Collectives, Annapurna Labs

Amazon Amazon · Big Tech · Cupertino, CA · Software Development

Software Engineer role focused on optimizing collective operations for AWS Trainium, a purpose-built AI training chip. The role involves enhancing collective algorithms and topologies, identifying bottlenecks, and optimizing communication patterns to scale AI compute across the data center, working closely with hardware teams.

What you'd actually do

  1. Enhance collective algorithms and topologies for optimal training performance
  2. Use tools like Neuron Explorer to identify bottlenecks in compute and bus bandwidth utilization
  3. Monitor and analyze processor, DMA, firmware, and workload metrics
  4. Optimize collective operations to scale AI compute across the data center
  5. Work closely with the hardware team to co-optimize software and Trainium silicon

Skills

Required

  • Bachelor's degree in computer science or equivalent
  • 5+ years of Experience building complex software systems that have been successfully delivered to customers
  • 5+ years of Experience contributing to the architecture and design (architecture, design patterns, reliability and scaling) of new and current systems
  • C/C++

Nice to have

  • Master's degree in computer science or equivalent
  • Familiarity with collective communication algorithms (e.g., all-reduce, all-gather) or distributed training frameworks

What the JD emphasized

  • optimize compute for the specific topologies used to train modern LLMs
  • fully utilize compute and bus bandwidth to scale across the data center
  • impact how AI training runs at AWS scale

Other signals

  • AWS Trainium
  • optimize collective operations
  • scale AI compute across the data center
  • frontier AI models
