Tezza Business Solutions Ltd

Remote

Role Purpose

Executes and automates the API test suite, and builds and maintains the committed automation regression pack for the programme.

Key Responsibilities

Execute API test cases: contract correctness, status codes, schema validation, version and backward-compatibility.
Build and stabilise mobile UI automation (Appium) and API automation (RestAssured) scripts for the committed automation scope.
Integrate automation into CI/CD execution waves — smoke tests on every build, regression nightly, extended suite pre-release.
Stand up service-virtualization mocks for third-party payment-rail and identity-verification dependencies during initial environment setup, so early testing isn't blocked by sandbox availability.

Required Qualifications & Experience

Demonstrated API test automation experience (RestAssured or equivalent).
Demonstrated mobile UI automation experience (Appium or equivalent).
CI/CD pipeline integration experience.

Required Skills & Tools

RestAssured, Postman/Newman, Appium, Java or Kotlin, CI/CD platforms (e.g. Jenkins, GitHub Actions).

What Success Looks Like

Committed automation scope is scripted, stable, and integrated into CI/CD before code freeze; the regression suite runs in hours, not days.
