About The Position

At Remitly, we believe everyone deserves the freedom to access, move, and manage their money wherever life takes them. Since 2011, we've tirelessly delivered on our promise to customers sending money globally, providing secure, simple, and reliable ways to manage their money, ensuring true peace of mind. Whether it's supporting loved ones back home, growing a business across continents, or pursuing new opportunities abroad, we're not just here to move money. We're here to move our global customers forward. We're looking for builders, reimaginers, and global thinkers who want to work at the intersection of technology, trust, and transformation. If that's you and you're ready to do the most meaningful work of your career, we invite you to join over 2,800 passionate Remitlians worldwide who are united by our vision to transform lives with trusted financial services that transcend borders. About the Role The Remittance Transaction Engine (RTE) team owns the systems at the very heart of Remitly: the platform that accepts, orchestrates, and tracks every remittance our customers send. Every transaction, across millions of customers and 170+ countries, flows through RTE services. We provide the transaction gateway, processing, and search/read surfaces that customer-facing products and internal teams across Remitly build on. On systems where correctness directly affects customers' money, we prioritize reliability and operational excellence at scale. This is a pivotal moment for the team: we are engineering a future-ready Transaction Platform, focused on transitioning to a modern, API-first architecture that empowers self-service integration for diverse product offerings at scale and migrating the company off legacy access patterns to a clean, API-first architecture. You'll help design that future while operating the Tier-1 systems that Remitly's business runs on today. As a Software Development Engineer II on the team, you'll design and build backend services end-to-end, collaborate closely with product managers and partner engineering teams, and raise the bar for quality and operational excellence on systems where correctness directly affects customers' money. You'll work in an AI-forward engineering culture: we expect engineers to leverage AI tools effectively across coding, testing, debugging, and documentation to move faster, while owning the correctness of everything they ship. Verifying and fully understanding AI-assisted output matters even more on systems that move money.
