Description

About Xe

Xe is a cross-border payments platform. We help SMEs and consumers in the US, UK, Canada, Australia, and New Zealand collect, convert, hold, and send money across markets. Each year, over 300 million people use Xe for currency information and over 350,000 use us to send money overseas. Today, we're rebuilding the platform layer behind cross-border payments for corporate and consumer clients. We're small enough that your code ships fast and your decisions matter, and Euronet Worldwide (Nasdaq: EEFT) backs us so the problems stay real-scale.

About This Role

We're hiring a senior QA engineer who owns quality end-to-end and shapes how the team tests, from test design and automation infrastructure through to release gating and production observability. You already use AI as part of how you think, build, test, and ship. You'll catch problems before code that moves money hits production, design the test automation other engineers depend on, and lead modernization of the test estate as new capability ships. You'll work in a small team with direct access to engineering, product, and compliance, own quality strategy for your domain, lead test architecture decisions, mentor mid-level QA engineers, and partner with architects and team leads on cross-domain quality decisions.

What You'll Do

• Design and own integration test harnesses and contract tests for the flows that move money, across a range of domains and the partner APIs behind them.
• Lead the design of the test automation that gates code into production, across onboarding, KYC and KYB, payment initiation, FX, settlement, and other supporting flows.
• Set the balance of manual and automated testing for your domain: write test cases, run manual tests where they are the right tool, and lead automation in Playwright and equivalent frameworks.
• Own CI/CD quality strategy for your domain (release-blocking signals, flaky-test triage, test infrastructure health), lead production incident investigation, and translate findings into automated tests and process improvements.
• Lead design reviews of test architecture, set quality direction for your domain, and mentor mid-level QA engineers.
• Use agentic coding tools and AI test tools (Copilot, Cursor, Claude Code, or equivalent; test generation, eval frameworks, or equivalent) daily, and lead the build of the test estate for new capability on the modern stack.

What We're Looking For

Must-have

• 6 to 10+ years building production test automation, end-to-end.
• Strong test automation skills in JavaScript, TypeScript, Python, or C#, including test framework design, system design, and test architecture experience.
• SQL and relational database fundamentals (for test data, validation, and debugging).
• API testing (Postman, Bruno, or equivalent) and UI automation (Playwright, Cypress, or equivalent).
• Functional and non-functional testing principles (reliability and security) and disciplined defect management, with hands-on performance, load, or resilience testing (k6, JMeter, or equivalent).
• Comfortable generating test cases and running manual tests where they are the right tool, alongside building automated coverage.
• Daily use of agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) and AI test tools (test generation, eval frameworks, or equivalent) across the SDLC.
• Production experience with AWS in a development or test context, and CI/CD pipeline ownership (GitHub Actions or equivalent), including building release gates.
• Payments, FX, or regulated-industry experience.
• Track record of QA technical leadership: setting test architecture, leading code reviews of test automation, and making quality decisions in your domain.
• Strong written and verbal communication.

Nice-to-have

• Experience with contract testing for partner integrations (Pact or equivalent).
• Experience testing Windows client applications.
• Mobile app test automation.
• Experience leading modernization of test estates or quality programs.

Perks & Benefits

• Competitive Salary & Discretionary Bonus
• 23 days annual leave increasing with service (capped at 28 days)
• Paid day off for your Birthday
• 4% employer pension contribution
• Discounted Euronet ESPP
• Life Cover, Income Protection & Critical Illness cover
• Healthcare
• Plumm Mental Health and Wellbeing
• Volunteering day for a charity of your choice
