Job summary

Xe is hiring a senior QA engineer to own quality end-to-end for cross-border payments platform. You will design test automation, architect testing strategies, and mentor mid-level QA engineers within a small cross-functional team including engineering, product, and compliance.

You’ll implement integration tests, automate release gates, and lead modernization of the test estate using Playwright and AI-assisted tooling across onboarding, KYC/KYB, payments, FX, and settlement.

Qualifications

• 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.

Responsibilities

• 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.
