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.
What the Scale Team Does
- Embedded Finance Platform: Build and maintain the multi-tenant infrastructure powering companies like Rippling, Navan, Qantas, and SHEIN. You'll architect systems that aggregate requests from all platform customers, meeting enterprise-grade SLAs for availability, latency, and throughput while handling cross-data-center scenarios.
- Cross-Domain Product Features: Own features that require synthesizing knowledge across business, regulatory, and technical domains—areas where no single existing team has full coverage, like tax systems, compliance-driven flows, or monetization tools.
- Solutions Architecture: Design integrations for enterprise prospects by translating their business requirements into technical solutions. Your architectural decisions directly influence deal outcomes—from enabling multi-million dollar contracts to differentiating in competitive sales.
Who You Are
You might be a great fit if you:
- Have 3+ years of software engineering experience in ReactJS & TypeScript.
- Excel at making the right level of abstraction—balancing flexibility and simplicity in system/component design.
- Demonstrate clean communication across technical and non-technical stakeholders.
- Make pragmatic decisions on when to optimize for performance vs. velocity based on business impact.
- Thrive in cross-functional environments spanning Product, Design, Compliance, and Sales.
- Design for scale, maintainability, and production excellence.
Bonus if you have:
- Fintech, payments, or regulated industry experience.
- Experience with OAuth2.0, API design, or developer documentation.
- Solutions engineering or customer-facing technical experience.
- Experience building BFF services or API aggregation layers (Node.js or similar).
- Comfort working across the stack—taking on scoped backend tasks when it improves delivery speed.
- Strong product sensibility and user empathy, with experience incorporating user research into technical decisions.
Why Join Us
- Build Something That Matters: Your work directly impacts how millions of people use financial services. Companies like Rippling and SHEIN rely on infrastructure you'll build.
- Grow Beyond Engineering: You'll develop expertise that extends beyond technical skills: understanding customer business models, navigating regulatory landscapes, influencing enterprise sales.
- Join a World-Class Team: Work with exceptional engineers, product thinkers, and designers across the globe. At Airwallex, you'll be challenged, supported, and surrounded by people who are building something meaningful together.
