Payments Engineer - credit card processing infrastructure - TypeScript React, NestJS Postgres Prisma, AWS (SQS/SNS/Lambda)

As a Payments Engineer, you will have the opportunity to join our growing Engineering team and report to the Head of Engineering and CTO. You will be staffed directly on one of our highest-leverage new initiatives: building credit card processing infrastructure from the ground up — including acquirer integration, PCI-scoped data handling, and modern checkout flows that power card-based pay-ins and pay-outs across our platform. This is a core new piece of Mural's infrastructure, and we're hiring someone who has done this before and can come in with thesis-backed opinions on how and why to build it a certain way.
