About the Role

At Klaviyo, the ARIA (Applications, Resources, Intelligence, and Automations) team is building AI systems that transform how our employees work. As an AI Builder Resident, you’ll join a cohort of builders focused on developing AI-powered internal tools that automate workflows, improve knowledge access, and unlock productivity across the company.

This is a 1-year, hands-on builder program (starting June 22, 2026) designed for candidates who have demonstrated the ability to build real things with AI. You’ll embed directly with business teams, working on high-impact problems and shipping production-ready agentic AI solutions. This role focuses on building and deploying agentic and LLM-powered applications in production, with an emphasis on learning, execution, and growing your ability to work across the AI system stack.

This role sits at the intersection of engineering, product thinking, and real-world problem solving. It emphasizes execution, curiosity, and ownership, with the expectation that you’ll actively build, iterate, and deploy—not just observe. This role is designed to accelerate your growth by giving you direct ownership of real problems and production systems from day one.

How You’ll Make an Impact

Embed with business teams to identify opportunities: Partner with internal teams to uncover workflow inefficiencies and translate ambiguous business problems into AI-powered solutions. Own problems end-to-end from discovery through deployment, not just execution.
Build AI-powered workflow automations: Design and implement solutions that automate repetitive or complex tasks using LLMs and agentic workflows.
Develop agent-based systems and integrations: Build AI agents that can take actions, chain tasks, and integrate with internal systems (e.g., HR, CRM, ticketing tools). Surface insights and patterns from deployments to inform broader AI platform and tooling improvements
Ship internal AI tools into production: Use AI-assisted coding tools to rapidly prototype, gather feedback, iterate, and deploy scalable, production-ready systems used by teams across Klaviyo. Ensure solutions are adopted and deliver real impact.
Advance team AI maturity: Help teams move from basic AI usage to
