Member of Technical Staff (Software Engineer, Agentic Commerce)

Perplexity is seeking a Software Engineer to own and evolve the billing platform that powers monetization across all Perplexity products. You'll build the abstractions and infrastructure that let product teams launch new paid offerings, run pricing experiments, and convert users into paying customers — without needing to understand billing internals. This is a high-leverage role on a small team. The usage-based billing system this team owns is the foundation that monetizes Perplexity Computer and our agentic products — metering every action an AI agent takes in real time, enforcing credit budgets, and settling costs across entirely new interaction models. You'll work across subscriptions, usage-based billing, and enterprise contracts to ensure every revenue path is reliable, observable, and easy to extend.
