• Has shipped conversational agents or agent harnesses at scale, using text or voice.
• Experience developing evaluation and tracing infrastructure for AI agents.
• Full-stack software engineering background and applied LLM experience; familiarity with agent frameworks, voice AI, SMS integrations, or multi-agent orchestration is valuable.
