Pytorch Jobs in Seattle, WA (NOW HIRING)

The Annapurna Labs team at Amazon Web Services (AWS) builds AWS Neuron, the software development kit used to accelerate deep learning and GenAI workloads on Amazon's custom machine learning accelerators, Inferentia and Trainium.
The AWS Neuron SDK, developed by the Annapurna Labs team at AWS, is the backbone for accelerating deep learning and GenAI workloads on Amazon's Trainium ML accelerators. This comprehensive toolkit includes an ML compiler, runtime, and application framework that seamlessly integrates with popular ML frameworks like PyTorch and JAX enabling unparalleled ML inference and training performance.
The Training Enablement and Foundation team is at the forefront of running a wide range of models and supporting novel architecture alongside maximizing their performance for AWS's custom ML accelerators. Working across the stack from PyTorch till the hardware-software boundary, our engineers build systematic infrastructure, innovate new methods and create high-performance kernels for ML functions, ensuring every compute unit is fine tuned for optimal performance for our customers' demanding workloads

We combine deep hardware knowledge with ML expertise to push the boundaries of what's possible in AI acceleration.
As part of the broader Neuron organization, our team works across multiple technology layers - from frameworks and kernels and collaborate with compiler to runtime and collectives. We not only optimize current performance but also contribute to future architecture designs, working closely with customers to enable their models and ensure optimal performance. This role offers a unique opportunity to work at the intersection of machine learning, high-performance computing, and distributed architectures, where you'll help shape the future of AI acceleration technology
You will architect and implement business critical features, and mentor a brilliant team of experienced engineers

We operate in spaces that are very large, yet our teams remain small and agile. There is no blueprint. We're inventing.

We're experimenting. It is a very unique learning culture. The team collaborates with open source ecosystems to provide seamless integration and bring peak performance at scale for customers and developers.
This role is responsible for development, enablement and performance tuning of a wide variety of LLM model families, including massive scale large language models like the Llama family, DeepSeek and beyond

Key job responsibilities
This role will help lead the efforts in building distributed training support for Pytorch/JAX in the Neuron SDK. This role will enable frameworks, tune models to ensure highest performance and maximize the efficiency of them running on the customer AWS Trainium silicon and servers. Strong software development using Python, C++, System level programming and ML knowledge are both critical to this role.

Our engineers collaborate across compiler, runtime, framework, and hardware teams to optimize machine learning workloads for our global customer base. Working at the intersection of software, hardware, and machine learning systems, you'll bring expertise in low-level optimization, system architecture, and ML model acceleration. In this role, you will:
* Design, develop, and optimize machine learning models and frameworks for deployment on custom ML hardware accelerators.
* Participate in all stages of the ML system development lifecycle including distributed computing based architecture design, implementation, performance profiling, hardware-specific optimizations, testing and production deployment.
* Build infrastructure to systematically analyze and onboard multiple models with diverse architecture.
* Analyze and optimize system-level performance across multiple generations of Neuron hardware
* Conduct detailed performance analysis using profiling tools to identify and resolve bottlenecks
* Conduct comprehensive testing, including unit and end-to-end model testing with continuous deployment and releases through pipelines.
* Work directly with customers to enable and optimize their ML models on AWS accelerators
* Collaborate across teams to develop innovative optimization techniques
A day in the life
You will collaborate with a cross-functional team of applied scientists, system engineers, and product managers to deliver state-of-the-art inference capabilities for Generative AI applications

Your work will involve debugging performance issues, optimizing memory usage, and shaping the future of Neuron's inference stack across Amazon and the Open Source Community. As you design and code solutions to help our team drive efficiencies in software architecture, you'll create metrics, implement automation and other improvements, and resolve the root cause of software defects.
You will also build high-impact solutions to deliver to our large customer base and participate in design discussions, code review, and communicate with internal and external stakeholders. You will work cross-functionally to help drive business decisions with your technical input

You will work in a startup-like development environment, where you're always working on the most important initiative.
