About the role

We are looking for a QA Engineer (manual-first, API-heavy) to keep a payments platform stable during frequent releases and occasional urgent hotfixes. We don't run strict sprint cycles, so you should be comfortable in a Kanban / continuous delivery setup: clarifying scope, building lightweight test coverage, and shipping fast without breaking critical payment routes.

You will focus on risk-based testing of payment flows, end-to-end API validation (including webhooks), and maintaining pragmatic regression/smoke checklists that balance speed and safety.

Key Responsibilities

• Manual testing: validate new features, fixes, and hotfixes across Web UI + APIs.

  Risk-based testing: define test scope based on financial / customer impact; call out residual risks.

  API / E2E validation: test REST APIs, async flows, and webhooks using Postman/Newman (or equivalent).

  Data validation: verify state transitions and side effects in PostgreSQL
