The Role We're looking for an SDET who thinks like an engineer and tests like one too. You won't be writing test cases in a spreadsheet. You'll be designing and owning test infrastructure for financial-grade systems — payment flows, KYC pipelines, card transaction handling, and the compliance rails that underpin them. This is not a QA role. It's an engineering role that happens to own quality as its primary output surface. You will work embedded in a team that ships production financial software at startup velocity. That means your job is to make speed and correctness coexist — not to be the brake pedal.
What You'll Own Test automation platform for Money Movement: end-to-end tests, API contract tests, integration test suites covering funding rails, card transactions, KYC flows, and Cash account operations. CI/CD quality gates : design, implement, and maintain test pipelines that run on every PR and block regressions from reaching production. Failure mode coverage : model the real failure modes — duplicate charges, partial KYC completions, webhook replay, idempotency violations, provider outages — and build tests that catch them before users do. Performance and load testing : validate that payment flows hold up under peak load; identify latency regressions before they hit p95 in production. Test data and environment infrastructure : own the tooling that makes tests repeatable, isolated, and fast. Observability for test quality : track test coverage, flakiness rates, bug escape rates, and regression detection latency as real metrics with real owners.
