## Job description

## About Airwallex

Airwallex is the AI-native financial operating system for a real-time, intelligent economy. 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. We 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. We're co-headquartered in San Francisco and Singapore, with more than 2,700 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 our[operating principles](https://www.airwallex.com/en-us/operating-principles) to see it in full.

## How you'll make impact

You’ll build frontend experiences and platform capabilities that help companies embed Airwallex financial products at speed and with confidence. You’ll work with ReactJS and TypeScript to support multi-tenant systems, cross-domain product features, and enterprise integrations serving global customers such as Rippling, Navan, Qantas, and SHEIN. You’ll translate complex business, regulatory, and technical requirements into scalable, maintainable user experiences, balancing tenant isolation, performance, resilience, and delivery speed.

- Build frontend capabilities for multi-tenant platforms, balancing tenant isolation with resource efficiency and long-term extensibility.
- Own cross-domain product features that bring together business, regulatory, and technical requirements.
- Design enterprise integrations by translating customer business needs into scalable technical solutions.
- Partner with Product, Design, Compliance, and Sales to turn complex requirements into clear, reliable experiences.
- Make pragmatic trade-offs between performance, maintainability, and delivery speed based on business impact.

You’ll work from the Singapore office five days a week.

## What we're looking for

Essentials

- 5+ years of software engineering experience with ReactJS and TypeScript.
- Strong judgment in choosing the right level of abstraction, balancing flexibility and simplicity in system and component design.
- Clear communication across technical and non-technical stakeholders.
- Pragmatic decision-making on when to optimise for performance versus velocity based on business impact.
- Experience thriving in cross-functional environments spanning Product, Design, Compliance, and Sales.
- A track record of designing for scale, maintainability, and production excellence.

## Preferred

- Experience in fintech, payments, or another regulated industry.
- Experience tuning performance at high scale, including 100k+ QPS, large user bases, or strict latency SLAs.
- A background in multi-tenant SaaS or platform architecture.
- Proficiency with PostgreSQL, Redis, Kafka, or cloud platforms such as AWS, GCP, or Azure.
- Experience with OAuth 2.0, API design, or developer documentation.
- Experience with cross-region deployment or data residency compliance.
- Solutions engineering or customer-facing technical experience.

You'll thrive here if

- You've worked in a high-growth or scaling environment and know what it takes to build systems that need to grow with the business.
- You're comfortable with ambiguity. Give you a problem, not a prescription, and you'll run with it.
- You communicate clearly and directly across cultures, and you're thoughtful about how context shifts meaning across borders.
- You know when to align and when to just decide. Collaboration isn't a way to avoid accountability.
- You simplify complexity rather than hiding behind it.
