Hands-on experience with LLMs, AI-assisted engineering, or agentic systems, including tool/function calling, agent workflows, and multi-step AI workflows.
Experience or familiarity with LLM and agent evaluation, evaluation datasets, deterministic evaluators, model-based evaluators, and probabilistic systems.
Strong understanding of the testing pyramid and validation across unit, integration, API, UI, performance, and agentic layers.
