About the Team

The AI Engineering team at Airwallex is a group of passionate builders and problem-solvers who are obsessed with creating elegant, scalable, and resilient systems that power customer-centric experiences. We operate like a start-up within a scale-up, building innovative technology to tackle a trillion-dollar opportunity. Our engineers bring deep technical expertise and a practical mindset, balancing long-term architecture with rapid, thoughtful execution.

This role will be part of our newly formed AI team, where we are setting out to build Agentic Finance as we prepare for a post-SaaS world and move up the value chain from delivering not just finance infrastructure and tooling, but finance work.

What you'll do

You'll build the frontend interfaces that connect users with AI agents performing real financial work. This includes designing responsive, high-performance UIs that surface agent reasoning, status, and outcomes in real time. You'll collaborate with ML, DS and backend engineers to translate complex systems into clear, intuitive user experiences.

Responsibilities:

• Lead the delivery of complex frontend features using React and TypeScript, including technical scoping, requirements breakdown, estimation, and strategic planning in collaboration with cross-functional teams.
• Architect and maintain micro-frontend applications following domain-driven design principles to ensure modularity, scalability, and performance.
• Partner closely with product managers and key stakeholders to shape the product roadmap, prioritise initiatives, and deliver iteratively with measurable impact.
• Own and evolve our frontend-backend integration layer using Apollo GraphQL, building robust backend-for-frontend (BFF) services that scale with the product and team needs.
• Guide and collaborate with design teams to develop and evolve a shared design system and component library that balances consistency and flexibility.
• Drive excellence through active leadership across Frontend, mentoring peers, championing best practices, reducing technical debt, and introducing innovative tools and frameworks.
• Foster a culture of quality, performance, and reliability by working across teams to ensure operational excellence and a polished user experience.
