Original job description

We are building foundational LLMs for Amazon Stores that fuse world knowledge with deep e-commerce understanding to power next-generation shopping experiences. These systems continuously learn from real-world customer interactions to become more helpful, personalized, and context-aware over time.

We are looking for builders who are passionate about large-scale systems, AI innovation, and customer impact. You will work at the intersection of distributed systems, machine learning infrastructure, and science to bring frontier research - especially in post-training and reinforcement learning - into production at Amazon scale.

Key job responsibilities

Architect and build scalable ML infrastructure powering LLM training and post-training workflows, including supervised fine-tuning, reinforcement learning, and continuous learning from live traffic
Transform real-world customer interactions into high-quality training signals, enabling continuous model improvement and better customer experiences
Build and optimize post-training and RL systems, including reward modeling, policy optimization, data collection loops.
Drive experimentation and iteration velocity by building tooling and frameworks that enable rapid hypothesis testing, signal validation, and model quality improvements
Partner closely with applied scientists to translate frontier techniques (e.g., RLHF, agentic workflows, multi-turn optimization) into reliable, production-grade systems
Own systems end-to-end, including design, implementation, deployment, observability, and operational excellence
Raise the engineering bar through technical leadership, design reviews, and mentorship, influencing best practices across the organization 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 vLLM, SGLang, TensorRT or similar platforms in production environments
Experience with CUDA kernels or ML/low-level kernels 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 with Machine Learning and Large Language Model fundamentals, including architecture, training/inference lifecycles, and optimization of model execution
