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 2,300 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 to see it in full.
As an Engineering Lead, Scale, you’ll lead a team building critical platform capabilities for Airwallex’s embedded finance products. You’ll manage engineers directly and be accountable for team health, execution, and long-term technical quality, while staying technically credible and involved at an architectural level.
Own technical direction for scalable, reliable backend systems and partner with senior engineers on architecture and design.
Drive high standards for system design, code quality, testing, and operational excellence.
Improve reliability, observability, security, and developer productivity across the team.
Partner with product, design, compliance, sales, and engineering leaders to align execution with business priorities.
Translate enterprise customer and commercial requirements into pragmatic technical solutions.
Coach and grow engineers through feedback, performance management, and career development.
You’ll work from our London office three days a week.
What we're looking forEssentials
5+ years of software engineering experience, with at least 1+ years in a people leadership role.
Strong backend development experience with an object-oriented programming language.
Proven experience designing and operating large-scale, distributed production systems.
Strong system design and object-oriented design fundamentals.
Ability to balance abstraction, simplicity, and speed in technical decision-making.
Excellent communication and stakeholder management skills.
Demonstrated ability to mentor engineers and lead technical execution.
Preferred
Experience in fintech, payments, or other regulated domains.
Experience with multi-tenant SaaS or platform architecture.
Familiarity with PostgreSQL, Redis, Kafka, and cloud platforms such as AWS or GCP.
Experience with API design, OAuth 2.0, or developer-facing platforms.
Exposure to cross-region deployment, data residency, or customer-facing technical architecture.
You’re comfortable owning the roadmap yourself.
You’re comfortable with ambiguity. Give you a problem, not a prescription, and you’ll run with it.
You own the outcome and you don’t wait for permission to fix what’s broken.
You connect dots across functions and hold the big picture without losing grip on the details.
You simplify complexity rather than hiding behind it.
The Scale team builds the infrastructure that lets platforms embed Airwallex financial products at speed and with confidence. The team owns multi-tenant systems powering companies like Brex, Rippling, Navan, Qantas, and SHEIN. The engineering challenges are real: balancing tenant isolation with resource efficiency, low-latency performance with cross-data-center resilience, and immediate customer needs with long-term architectural extensibility. Beyond infrastructure, the team owns cross-domain product features and designs enterprise integrations by translating customer business requirements into scalable technical solutions.

Sales
Our London office is scaling fast. We're a 140+ strong team and growing, and our Sales team is right at the heart of it. The momentum is real: we're investing over $1bn into the region and $590m into the UK. Revenue is up 116% year on year and volumes have surged 226%, and we’ve only captured a fraction of what’s possible. That's where you come in. You'll be selling a world-class proven product into a market that's still wide open. Global heavyweights like McLaren Racing, Arsenal, Bolt, Qantas, and Carwow already run on Airwallex. For you, that means real ownership from the start, a role you'll scale, and scope that grows as fast as you can sell. It's a rare moment to join: proven product, open market, and a team going places
