• Define and track key performance indicators (KPIs) and service level objectives (SLOs) for large-scale, LLM inference services

• Formulate and execute performance benchmarks utilizing tools like vLLM, GuideLLM, and PyTorch Profiler and other related tools to characterize performance, drive improvements, and detect issues through data analysis and visualization.

• Develop and maintain tools, scripts, and automated solutions that streamline performance benchmarking and AI model profiling tasks.

• Collaborate closely with cross-functional engineering teams to identify and address critical performance bottlenecks within the architecture and inference stacks.

• Partner with DevOps to bake performance gates into GitHub Actions/RHAIIS Pipelines.

• Explore and experiment with emerging AI technologies relevant to software development, proactively identifying opportunities to incorporate new AI capabilities into existing workflows and tooling.
