** Your Mission

- Analyse business requirements, functional specs, and user stories to design comprehensive test cases and scenarios.

- Perform end-to-end testing of transaction lifecycles, covering initiation, authorisation, settlement, and reconciliation.

- Explore the platform proactively for edge cases, risks, and behaviour the specs did not anticipate.

- Validate data accuracy and consistency across services using SQL queries against PostgreSQL or MySQL.

- Test REST and gRPC endpoints with Postman, grpcurl, or similar, to verify request and response behaviour.

- Verify event-driven flows across message queues such as Kafka, RabbitMQ, or NATS, including retries and duplicate handling.

- Write and extend automated tests in Go for regression-critical paths, working with the engineering team where needed.

- Log, track, and manage defects in Jira with clear reproduction steps, payloads, and service logs.

- Run regression testing after every deployment.

What You Bring

- 4+ years of manual testing experience with a focus on backend services and APIs.

- Domain experience in iGaming, Fintech, payment gateways, or banking platforms.

- Proficiency in writing intermediate SQL queries to validate data in relational databases.

- Hands-on experience with API testing tools such as Postman, and test management tools such as TestRail or Zephyr.

- Able to read Go and write or extend tests in it. Prior automation experience in any language is fine if you are willing to work in Go.

- Working knowledge of Docker and the ability to spin up services locally for testing.

- Solid understanding of Agile/Scrum methodologies and the Software Testing Life Cycle (STLC).

- Strong analytical and problem-solving skills with meticulous attention to detail.

Nice to Have

- Existing Go experience.

- Experience supporting UAT with business stakeholders.

- Exposure to CI/CD pipelines.
