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. 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. # What you’ll do
Our mission is to keep Airwallex’s products and services safe and secure. We continuously improve risk strategies and systems using modern technologies, including graph, machine learning, and LLMs/Gen AI, to detect and prevent fraud and abuse at scale. ### Responsibilities:
- Design, develop, and operate core transaction risk services and infrastructure using Kotlin/Java, supporting payment products and transaction systems. - Own end-to-end delivery of key components and services on Airwallex’s microservice framework: design, implementation, testing, deployment, and observability. - Build high-concurrency, highly available distributed services, optimizing latency, throughput, and reliability for production workloads. - Collaborate with senior engineers and cross-functional partners to define technical solutions, APIs, and service boundaries; drive architectural improvements. - Explore and evaluate new technologies (e.g., graph/streaming/ML/LLM related) and propose pragmatic upgrades aligned with business risk needs. - Mentor engineers through code reviews, design discussions, and engineering best practices, improving team quality and delivery efficiency. - Participate in on-call/incident response when needed, driving root-cause analysis and long-term remediation. #
