Experience with agent SDKs and harnesses (such as Claude Code / Agent SDK, OpenAI Agents SDK, LangGraph, or similar) and LLM observability tooling, eval tooling such as Braintrust or MLflow, and model APIs from Anthropic, OpenAI, and Google. Own the architecture of the shared GTM AI platform: orchestration, LLM and tool gateways, identity and access, and the MCP and SDK contracts that let the GTM web app, Salesforce, Slack, desktop, and Claude plugins share one set of governed capabilities.
