# AIML - Sr. LLM Inference Quality Engineer

Apple is building the next generation of AI data center infrastructure to power large language model (LLM) services at scale. We are looking for a senior engineer to own the correctness, consistency, and stability of LLM inference in production. You will design and build the automation frameworks, evaluation methodology, and qualification strategy that give us confidence in every model, prompt, serving stack, and infrastructure change before it reaches our users. Your work is the safety net that lets Apple ship frontier AI quickly, without sacrificing quality, safety, or trust. Description In this role, you will lead the qualification of an LLM inference, output-correctness, automation framework for large-scale AI data center deployment and platform validation. You will architect qualification systems for generative AI, including agentic workflows and tool-using models, running at data center scale, validating that outputs remain correct, consistent, and stable as models, weights, prompts, serving runtimes, quantization schemes, and accelerator hardware change underneath them. This is a hands-on AI systems engineering role at the intersection of machine learning, distributed system
