Hiring Location: London (Hybrid Mode)

Total Compensation: 140,000 to 200,000 GBP

About the Team

• 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.

What you'll do

• 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. You're not just writing code-you're shaping how businesses embed finance.
• Grow Beyond Engineering: You'll develop expertise that extends beyond technical skills: understanding customer business models, navigating regulatory landscapes, influencing enterprise sales. This is career growth that prepares you for technical leadership, product roles, or even founding your own company.
• 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.
