More than 675,000 businesses, including McLaren Racing, Qantas, SHEIN, and TikTok, use us, directly or through our platform partners, to run their financial operations or build and monetize financial products of their own.\nWe started in Melbourne in 2015 to build the infrastructure global commerce runs on. We're the regulated backbone behind global payments: not by accident, but by design. A decade plus, 85+ licenses, and a financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific.\nWe're co-headquartered in San Francisco and Singapore, with more than 2,300 people across 27 offices. We hire builders with founder-level energy, people who move fast with good judgment, dig in with real curiosity, and make calls from first principles rather than waiting to be told what to do. Read ouroperating principles to see it in full.\nHow you'll make impact\nYou'll architect distributed payment systems at global scale, designing and evolving core infrastructure across real-time local clearing, SWIFT, and proprietary treasury routing in 150+ countries.\nArchitect distributed payment systems at global scale, designing and evolving core infrastructure across real-time local clearing, SWIFT, and proprietary treasury routing in 150+ countries.\n\nSolve complex financial integrity problems by building idempotent, fault-tolerant systems for multi-currency reconciliation, asynchronous settlement, and compensation logic across unreliable banking partners.\n\nOwn the reliability and observability of the payment network by defining SLAs, designing for graceful degradation during partner outages, and building real-time payment health monitoring.\n\nUse payment telemetry to optimise routing, identify bottlenecks, and measure how infrastructure changes affect settlement speed and conversion.\n\nSet technical direction across a distributed engineering team by leading design reviews for platform-wide changes, collaborating with engineering hubs across the US, Singapore, Hong Kong, and Shanghai.\n\nYou'll work from our Seoul office five days a week.\nWhat we're looking for\nEssentials\n7+ years’ experience building and operating production software, including distributed systems at scale.\n\nStrong system architecture skills, with practical experience designing for fault tolerance, idempotency, asynchronous workflows, reconciliation, settlement, and failure recovery.\n\nExperience owning reliability for critical systems, including defining SLAs, designing graceful degradation, building observability, and leading incident response.\n\nStrong programming or scripting skills in a language such as Java, Kotlin, C++, Python or a similar language.\n\nA bachelor’s degree in Computer Science, Software Engineering, or a related field.\n\nExperience setting technical direction across multiple teams through design reviews, RFCs, and architecture decisions.\n\nStrong analytical skills, using operational and product data to guide technical decisions.\n\nPreferred\nExperience in fintech, payments, or other regulated financial domains.\n\nDeep experience with JVM-based ecosystems, including Java or Kotlin with Spring or Spring Boot.\n\nPrior experience leading teams responsible for high-availability, low-latency systems.\n\nYou'll thrive here if\nYou're comfortable owning the roadmap yourself.\n\nYou hold yourself to a high standard even when no one is watching. Quality and accountability aren't external expectations, they're internal ones.\n\nYou're comfortable with ambiguity. Give you a problem, not a prescription, and you'll run with it.\n\nYou enjoy working closely with people across multiple countries and time zones as part of one connected, global team.\n\nYou can advocate hard for a position, then fully support the team's direction once a call is made.\n\nLearn more about your team\nThe Global Treasury and Payment Network (GTPN) team sits at the heart of Airwallex’s payment infrastructure.
