Posted 2mo ago · via Lever
About this role
At CloudWalk, we are building the core infrastructure behind our credit card operation — from authorization to clearing — handling real-world financial transactions at scale.
This is not a typical backend role.
You will work on systems where latency matters, correctness is critical, and failures have real impact.
The Role
You will design and build the systems that authorize, process, and reconcile transactions in real time — ensuring performance, correctness, and security at every step.
Our stack is heavily based on Rust, and we operate with full ownership of the issuing flow, including authorization, clearing, and ledgering.
