How to Succeed

Analyze business use cases, functional specifications, solution designs, and acceptance criteria to define the right E2E test coverage.

Design and maintain test cases covering complete payment journeys across channels, APIs, processing components, and downstream systems.

Execute manual and automated E2E tests, including happy flows, unhappy flows, error handling, boundary conditions, and regression scenarios.

Validate payment data, statuses, and outcomes as transactions move between different systems.

Prepare and maintain test data, test accounts, access rights, and environment prerequisites.

Collect clear test evidence, including expected and actual results, logs, API responses, screenshots, and relevant transaction or message identifiers.

Retest resolved defects and perform targeted regression testing to ensure fixes don't create unintended impact elsewhere in the payment chain.

Build and maintain automated test suites and help move E2E scenarios from manual testing toward maintainable automation.

Collaborate across squads and domains to identify blockers, communicate quality risks, and drive issues toward resolution.

Around 3-6 years of experience in software testing or quality engineering.

Strong hands-on experience with end-to-end, system integration, API, functional, and regression testing.

Experience designing test cases based on business requirements, functional specifications, user journeys, and technical designs.

Experience building and maintaining automated test suites.

Practical experience with Postman, GitHub, GitHub Copilot, and modern automation frameworks such as Playwright.

A hands-on ownership mindset, taking responsibility from test preparation through execution, evidence, retesting, and follow-through.

Strong stakeholder management skills and the ability to translate complex testing topics into clear risks and decisions.

A proactive and resilient approach when priorities shift, dependencies create blockers, or delivery pressure increases.

Strong problem-solving, communication, and presentation skills.
