Powered by our unique combination of proprietary infrastructure and software, we empower over 250,000 businesses worldwide – including Brex, Navan, Qantas, SHEIN and many more – with fully integrated solutions to manage everything from business accounts, payments, spend management and treasury, to embedded finance at a global scale. Proudly founded in Melbourne, we have a team of over 2,300 of the brightest and most innovative people in tech across 27 offices around the globe. Valued at US$11 billion and backed by world-leading investors including T. Rowe Price, Visa, Mastercard, Robinhood Ventures, Sequoia, Salesforce Ventures, DST Global, and Lone Pine Capital, Airwallex is leading the charge in building the global payments and financial platform of the future. If you’re ready to do the most ambitious work of your career, join us. Attributes We Value We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you’re motivated by our mission and [operating principles](https://www.airwallex.com/us/operating-principles). You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor. You're humble and collaborative; turn zero‑to‑one ideas into real products, and you “get stuff done” end-to-end. You use AI to work smarter and solve problems faster. Here, you’ll tackle complex, high‑visibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let’s build what’s next. ## About the team Risk Platform builds the decisioning infrastructure that sits between Airwallex and every dollar that moves through it, protecting 150,000+ businesses moving over US$260 billion a year across 150+ countries and 60+ currencies, and deciding, often in milliseconds, whether a new signup is real, a payment is safe, or a login is who they claim to be. The hard part is that fraud evolves fast, and every decision carries a two-sided cost: miss an attack and money is lost, over-block and a legitimate business can't get paid. We build this with streaming pipelines processing billions of events a day, graph databases exposing coordinated fraud rings, ML models scoring every transaction, and LLM agents that triage alerts. You don't need a fintech background, just an appetite for adversarial systems problems where the scoreboard is measured in dollars. If you want to help scale one of the world's fastest-growing financial platforms safely, this is the team. ## About the Role As the first SDET on the Risk Platform team, you'll help the whole risk team decide and define what quality means for risk-critical systems — the standards, practices, and quality gates everyone builds around. You're an engineer first: you build the automation, tooling, and infrastructure that let us ship changes to these systems quickly and safely. Responsibilities: - Design, build, and maintain end-to-end and regression automation across the 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. ## Who you are We're looking for people who meet the minimum qualifications for this role. The preferred qualifications are great to have, but are not mandatory. Minimum qualifications: - Experience as an SDET / Software Engineer in Test, with strong programming skills and a track record of building test frameworks — not just writing test cases. - Solid experience testing large-scale distributed backend systems: REST APIs, message-driven flows, and service-to-service integrations. - Hands-on experience with API and E2E automation and CI/CD; experience with contract testing and managing test data and environments, or the ability to build these from the ground up. - A strong sense of what makes tests reliable: deterministic data, isolated environments, and fast feedback. - Use AI to accelerate testing — LLM-assisted test generation, coverage analysis, and failure triage — and help define how we test the team's ML models and LLM agents (evaluation, regression, and guardrails). - Comfort working in a self-directed, Agile team, with excellent written and verbal communication. Preferred qualifications: - Exposure to risk, fraud, payments, compliance, or other regulated financial domains. - Experience testing systems with jurisdiction- or region-specific behaviour. - Experience with contract testing tools (e.g. Pact) and building test-data / environment tooling from the ground up. - Experience using AI/LLM tools in the testing workflow, or testing ML- or LLM-based systems (evaluation harnesses, non-deterministic outputs). - Performance and latency testing for systems on the critical path. Life at Airwallex - Industry-leading salaries, plus equity for every employee. - Access to our mental wellness platform, including coaching and EAP sessions. - A paid day off on your birthday, generous parental leave, and paid volunteer leave.
