The Opportunity: Join Our Stablecoin Platform Team
The Financial Markets team is responsible for Airwallex’s core FX and liquidity infrastructure. We’re now expanding into building the stablecoin infrastructure that will enable both customers and internal systems to buy, hold, send, and settle with tokenised currency globally. This includes support for near-instant global payments, on-chain liquidity, and seamless conversion between fiat and stablecoin balances. We’re building stablecoins into the core of Airwallex’s infrastructure, so they function as seamlessly as any fiat currency across our global platform.

We’re looking for a talented and hands-on engineering leader to drive this work forward, someone who can both architect and build reliable systems, while guiding a high-performing team through the complexities of blockchain integration, digital asset custody, and global payments infrastructure.

What You’ll Do:

• Lead and grow a focused, high-impact engineering team building stablecoin infrastructure from the ground up.

• Design and implement secure systems for key management, transaction signing, gas fee management, and blockchain integration

• Own services that manage the full lifecycle of stablecoin transactions mint, burn, transfer, reconciliation

• Build internal ledgering systems that track balances across multiple chains and token types

• Integrate stablecoin infrastructure into Airwallex’s existing FX and payment systems, enabling seamless conversion between any supported currency and stablecoins

• Work hands-on with engineers to write, review, and ship production code

• Collaborate with product, infrastructure, and compliance teams to deliver reliable and auditable services

Who You Are:

• A highly experienced engineer (8+ years) with deep expertise in object-oriented design and production-grade software development, including at least one strongly typed language (e.g. Kotlin, Java, C#, C++, Rust); Python experience is useful but not sufficient on its own

• Comfortable leading a team while remaining hands-on. You set the technical bar by example, not by delegation

• Proven experience building and integrating blockchain infrastructure (wallets, transaction flows, key management, etc.) into larger financial systems

• Experienced in integrating new systems into legacy or distributed environments without introducing instability or regressions.

• Strong grasp of secure system design, particularly around private key handling, signing, encryption, and operational controls

• You mentor engineers through regular code reviews and technical guidance, and encourage sharing practical knowledge across the team

• Able to quickly pick up unfamiliar tools or frameworks when needed and adjust to changing technical priorities.

• Clear communicator who works well across engineering, product, and non-technical teams

• Bonus: experience in FX, payments, or financial infrastructure is useful but not required
