About the job

Set direction and build Klaviyo’s production conversational AI agent platform that helps brands serve their customers at scale.

What you'll do

  • Own technical and product direction for Customer Agent, from architecture through production.

  • Ship and review code, establish reusable frameworks, mentor through design reviews, and shape the roadmap with cross-functional partners.

What they ask for

  • Have architected, built, scaled, and supported a production agentic system end to end, including real orchestration, evaluations, guardrails, and non-deterministic failure handling.
  • Have secured production agents against misuse and abuse and maintained their reliability as usage grows.
  • Have set technical and product direction for a product area and championed work shipped and adopted by other teams.
  • Remain hands-on in coding, architecture reviews, and production debugging; communicate trade-offs clearly across technical and executive audiences.

Nice to have

  • Experience running a multi-tenant agent platform at production scale.
  • Experience with 0-to-1 products, production evaluation systems, AI observability, or human-in-the-loop workflows for LLM-powered products.
