Hi there!
Zapier’s Revenue Zone is where product meets payments — and where customers truly experience the value of Zapier. Whether they’re choosing a plan, managing their subscription, or checking usage, we believe those moments should feel effortless, transparent, and trustworthy.
We’re hiring a Full Stack Engineer to help us build and evolve the infrastructure behind these moments. You’ll work on the systems that power billing, payments, plan selection, usage tracking, and more — and play a critical role in making these experiences reliable, flexible, and user-friendly.
If you’re excited to build systems that directly influence how millions of users access Zapier and help ensure our business continues to grow sustainably — this is the role for you.
The Revenue Zone owns how Zapier is packaged, priced, and purchased — and how those systems evolve with our customers.
We work across two cross-functional teams:
Team Payments builds the systems behind billing, invoicing, subscription management, and payment processing. Their work ensures customers can reliably pay for Zapier — and get the value they expect.
Team Catalog focuses on how we present pricing, help customers choose the right plan, and support internal tooling for packaging and offers.
Together, we build and maintain the infrastructure that supports pricing, payments, subscriptions, and customer visibility into their accounts — while keeping reliability, performance and clarity top of mind.

• You value collaboration, pairing, and async communication in a remote team environment
• You’re customer-focused. Whether internal or external, you care about solving real problems and creating great experiences
• You love learning and are curious about ambiguous or novel problems. You’re comfortable asking questions, digging in, and figuring things out
