Overview
(Senior) Software Engineer, Backend - Stablecoin (Relocate to Singapore) – Join Airwallex to apply for this role.
About AirwallexAirwallex is the leading financial technology platform for modern businesses growing beyond borders. Our technology empowers businesses to accept payments, move money globally, and simplify financial operations in one platform. Airwallex has a global footprint across Asia-Pacific, Europe, and North America.
The OpportunityJoin our Stablecoin Platform Team. The Financial Markets team is responsible for Airwallex’s core FX and liquidity infrastructure. We are expanding into stablecoin infrastructure to enable customers and internal systems to buy, hold, send, and settle with tokenised currency globally, including near-instant global payments, on-chain liquidity, and fiat/stablecoin conversion. We are building stablecoins into the core of Airwallex’s infrastructure so they function as seamlessly as any fiat currency.
What You’ll Do- Be part of a 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
- Write, review, and ship production code
- Collaborate with product, infrastructure, and compliance teams to deliver reliable and auditable services
- 8+ years of experience 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
- Proven experience building and integrating blockchain infrastructure (wallets, transaction flows, key management) into larger financial systems
- Experience integrating new systems into legacy or distributed environments without introducing instability or regressions
- Strong grasp of secure system design, especially around private key handling, signing, encryption, and operational controls
- Able to quickly pick up unfamiliar tools or frameworks and adapt 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
- Be Part of Something Big: contribute to the core engine of user growth in a company reshaping global financial services
- Grow With Us: opportunities for professional development in a fast-paced, innovative environment
- Collaborate With the Best: work with talented colleagues driving extraordinary results
