Title and Summary

• Lead Software Engineer
• Test Automation/Java

We are looking for a Lead Software Engineer – Test Automation (Java) with 8+ years of experience in test automation to join the Developer Experience team, responsible for the Mastercard Developers portal and related tools used by developers globally.

This is a hands‑on technical leadership role focused on defining and driving test automation solutions, shaping quality practices, and ensuring consistent, production‑ready releases across teams. You will work closely with engineering teams to embed quality throughout the software delivery lifecycle while remaining actively involved in automation design and implementation.

This is a senior individual contributor role with broad technical ownership and responsibility for test automation direction and standards.

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

In addition, as a Lead, you will:

• Mentor and support junior team members in day‑to‑day work, coaching them on automation design, coding standards, and testing practices
• Help define and review the automation approach for the team, including framework structure, test architecture, and maintainability
• Partner with developers and tech leads on testability and architecture decisions (e.g., where to test, what to mock, how to structure contracts/integration points)
• Raise quality and automation standards through reviews, guidance, and continuous improvement initiatives

The balance between manual testing and automation is typically around 50/50, but may vary depending on the feature, its complexity, and delivery phase.
You will work take ownership of test automation strategy and quality practices across key areas of the platform.

WHAT WILL YOU DO:

• Own end‑to‑end testing for assigned features as part of a feature team (manual first, then automation)
• Design and implement automated tests in Java across API, UI, and integration layers
• Work closely with developers to identify, fix, and prevent defects
• Define and evolve the team’s automation approach, standards, and test architecture
• Review automation code and improve test stability and CI/CD feedback
• Mentor junior team members and guide them on testing and automation practices
• Influence testability and quality‑related architecture decisions with engineering leads

WHAT YOU BRING:

• Extensive experience (8+ years) in test automation
• Java programming skills applied to building automation frameworks and tooling
• Experience testing APIs, UI, and distributed systems at scale
• Proven ability to take technical ownership and guide quality initiatives
• Experience working across teams to influence testing and automation practices
• Strong understanding of CI/CD pipelines and modern delivery workflows
• Ability to communicate clearly and collaborate effectively with engineers and stakeholders

NICE TO HAVE:

• Experience with contract testing, performance testing, or testing in production
• Experience in cloud‑native or microservices‑based environments
• Familiarity with developer platforms or internal/external developer tools
