## Description

## About the Role

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.

## Key Responsibilities

- 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.

## Requirements

### 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.

## Benefits

- Work from the Singapore office five days a week.

## Culture Fit

- 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.
