Apply for this Role Share Role About jStack

jStack builds financial infrastructure that helps banks, fintechs, telecom operators, enterprises and governments launch and scale modern financial products across payments, wallets, mobile money, cards, stablecoins and emerging financial rails.

About the Role

You will own end-to-end delivery of services and interfaces across the jStack platform — from transaction APIs and ledger workflows to the dashboards our customers operate every day.

You will work closely with platform engineering, product and integration teams building against banks, card networks, telecom operators and blockchain rails.

The problems are concrete: correctness under load, predictable latency, clean abstractions over messy external systems, and interfaces that make complex money movement understandable.

This role matters because everything our customers launch runs on the foundations you build.
