You are visible, your talents are valued, and you are empowered to shape the future of payments.
JOB PURPOSE
We are looking for a Principal Software Engineer in Test who treats quality not as a gatekeeping function but as a property of the entire software delivery system. This engineer embeds quality thinking at every stage of the value stream - partnering with product, architecture, and engineering to define clear, testable acceptance criteria, and then coaching development teams to build and own fast, deterministic test suites themselves.
This is not a role that owns a separate test...
