Description

We're enhancing the shopping experience on Amazon through the conversational capabilities of large language models, and we're looking for innovative professionals who are passionate about technology and customer experience. You'll have the opportunity to drive breakthrough innovations in LLM inference efficiency while working alongside talented scientists, engineers, and technical program managers (TPMs) to create solutions that serve our customers.

If you're excited about optimizing the computational heart of AI systems, collaborating with a dynamic team, and contributing to this evolving field, we'd love to have you join our mission to unlock unprecedented LLM performance!

Key job responsibilities

We're looking for an experienced Software Development Engineer with deep expertise in GPU/customized chip kernel optimization and ML inference acceleration to lead projects in architecting, designing, developing, and optimizing high-performance kernel implementations for large language model. You'll guide your team in creating and optimizing innovative kernels, custom operators, and low-level optimizations that maximize hardware utilization and minimize computational overhead.

In this role, you'll establish best practices for kernel development, memory management, and parallel computing that dramatically reduce inference latency and boost throughput for transformer-based models. You'll work with your team to develop kernel fusion techniques, attention mechanism optimizations, and matrix multiplication accelerations at scale, partnering with engineers and scientists in a fast-paced environment to deliver measurable performance gains. You'll also drive technical roadmap, performance benchmarking, and optimizations focused on kernel-level improvements.

Basic Qualifications

- 5+ years of non-internship professional software development experience

- 5+ years of programming with at least one software programming language experience

- 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience

- Experience as a mentor, tech lead or leading an engineering team

- Experience with Machine and Deep Learning toolkits such as MXNet, TensorFlow, Caffe and PyTorch

- Experience with CUDA, cuDNN, cuBLAS and other GPU kernel-level optimization techniques

Preferred Qualifications

- 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience

- Bachelor's degree in computer science or equivalent

- Experience in Neuron hardware (Inferentia and Trainium chips) and NKI kernel optimization

- 3+ years of hands-on experience with CUDA programming and GPU kernel development
