AI Product Engineer at Notion — building the LLM-powered Custom Agents that automate recurring team workflows

This role builds the AI-powered features behind Notion's Custom Agents, which automate recurring workflows like filing tasks, writing reports, and answering knowledge-base questions. It's framed as an 'AI Product Engineer' position emphasizing prototyping with LLMs and embeddings, productionizing async workflows at scale, and cross-functional collaboration with AI, Infrastructure, and Product teams. The JD does not specify a hard years-of-experience floor for the core bar, though the nice-to-haves reference 10+ years as a stretch signal, so this reads as a mid-level bar with room for a strong generalist.
