Job summary

Airwallex Singapore is seeking a dedicated Quality Engineer (SDET) to build end-to-end testing for our Risk Platform. You’ll design automation, testing pipelines, and contract testing to ensure fast, safe deployments of risk decisions at scale.

You will collaborate with engineering and product teams, champion testability, and mentor others in test design, AI-assisted testing approaches, and reliable data practices to minimize production risk.

Qualifications

• Experience as an SDET / Software Engineer in Test with strong programming skills and test framework building.
• Solid experience testing large-scale distributed backend systems: REST APIs and service-to-service integrations.
• Hands-on API and E2E automation and CI/CD; experience with contract testing and test data/environments.

Responsibilities

• Design, build, and maintain end-to-end and regression automation across risk decisioning flows – onboarding (KYC/KYB, merchant risk), transaction scoring, and screening – and wire the suites into CI/CD so regressions are caught before release.
• Establish stable, reproducible test data and isolated environments, including realistic fraud, screening, and jurisdiction scenarios, so automation stays deterministic and trustworthy.
• Introduce and own contract testing between the Risk Platform and its upstream and downstream services to catch integration breakages early.
• Build jurisdiction-specific coverage that validates regional rules, thresholds, and regulatory requirements.
• Define and enforce release-quality gates, and design post-release verification (smoke tests, monitoring-backed checks) to confirm risk systems behave correctly in production.
• Own testing and release acceptance for major client-facing projects, end to end, partnering with engineering and product on acceptance criteria.
• Champion testability and quality across the team, and mentor engineers on test design and automation.
