Billing & Payments Engineering: The Billing & Payments Engineering team builds and owns the mission-critical systems that power 1Password’s revenue engine end-to-end. We are responsible for the highly available architecture that enables seamless subscription management, complex payment processing, and global financial compliance. From managing the intricate logic of the subscription lifecycle—creations, renewals, upgrades, and cancellations—to integrating with diverse payment gateways and app-store ecosystems, our work ensures a frictionless experience for our customers. As a team, we are actively architecting the next generation of our billing infrastructure, modernizing and consolidating our systems to support rapidly scaling product lines, guarantee absolute data integrity, and ensure robust integrations with downstream financial workflows.

How we’re using AI today

Our Engineering, Product, and Design teams are thoughtfully integrating AI across the full software and product development lifecycle to move faster without sacrificing quality or security. In practice, that looks like engineers using AI-assisted coding tools to accelerate reviews and catch bugs earlier, product managers synthesizing user research at scale, and designers rapidly prototyping and iterating with AI-generated mockups. We approach AI the same way we approach security: with clear principles, human accountability at every consequential decision point, and rigorous evaluation before anything ships to customers.
