Title and Summary

Software Engineer II

Software Engineer II - Test Automation/Java

We are looking for a Software Engineer – Test Automation (Java) with 3+ years of experience to join the Developer Experience team, responsible for the Mastercard Developers portal and related tools used by developers globally.

This is a hands‑on individual contributor role focused on building and maintaining high‑quality automated tests and frameworks. You will work closely with software engineers to embed test automation directly into the development workflow and ensure reliable, production‑ready releases.

This is an individual contributor role, with opportunities to grow in scope and responsibility over time.

HOW WILL YOU WORK

You will be an embedded member of a feature team and take end‑to‑end ownership of testing for assigned features.

For each feature, you will:

• Understand the feature and its requirements
• Test it manually first, exploring edge cases and real user scenarios
• Identify defects and work directly with developers to clarify issues and drive fixes
• Once the feature stabilizes, design and implement automated tests to ensure long‑term reliability

The balance between manual testing and automation is typically around 50/50, but may vary depending on the feature, its complexity, and delivery phase.

WHAT WILL YOU DO

• Own testing for assigned features as part of a feature team
• Perform manual and exploratory testing, identify defects, and work directly with developers on fixes
• Design and implement automated tests in Java (API, UI, integration)
• Ensure new features are covered by reliable automation before release
• Maintain and improve test stability and CI/CD integration

WHAT YOU BRING

• Experience in test automation or software engineering in test
• Very good Java skills used in automation or tooling
• Experience testing APIs, UI, and distributed systems
• Ability to combine manual testing and automation effectively
• Experience collaborating closely with developers in feature teams
• Familiarity with CI/CD pipelines and modern delivery practices

NICE TO HAVE

• Experience in cloud-native or microservices-based environments
• Familiarity with developer platforms or tools for external/internal developer experience

• Abide by Mastercard’s security policies and practices;
