About Happy Robot

Happy Robot is the infrastructure for enterprises to build and orchestrate AI work forces. Our AI workers don't just communicate - they make decisions, take action, and run operations autonomously across voice, email, and enterprise systems. Born in Y Combinator (S23) and backed by a16z and Base
10 with over $60M raised, we power critical operations for global enterprises worldwide.

Our platform is battle-tested in the most demanding environments - where AI has real consequences. We started in logistics, built our own voice stack, models, and orchestration layer from the ground up, and are now bringing that infrastructure to every enterprise that runs the real economy.

We're looking for an Infrastructure Engineer to take the lead on scaling our operational resilience as we grow.

• Experience working with distributed systems or services at scale
• Built or maintained internal tooling for on-call teams or reliability workflows
• Familiarity with deployment pipelines, CI/CD, or infra-as-code
• Experience improving system observability (e.g., custom metrics, traces, log pipelines)

• Opportunity to work at a high-growth AI startup
