Senior Fullstack Software Development Engineer

Job Description:

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:

App Platform Engineering builds and maintains the foundational mobile and web platform that all Remitly product teams build on top of. We own the architecture, shared frameworks, build and release infrastructure, design system, and developer tooling. These let product teams ship faster and with higher quality. This also eliminate the need for product teams to solve the same hard problems twice. As a senior development engineer you will report to senior engineering manager in Krakow and work with peer team based in Poland and U.S.

You Will:

• Own the architecture and evolution of our mobile and web platform - decisions that 10+ product teams depend on

• Build and maintain CI/CD pipelines, feature flagging, and safe rollout infrastructure — from pipeline design to app store delivery

• Lead the shared component library, design system, and localisation engine — partnering with UX to set standards for performance, accessibility, and observability

• Enable product teams through documentation, tooling, and architecture reviews — and help the team stay current on React Native and AI-assisted development

• Mentor junior engineers and uphold quality standards, including regulatory compliance

You'll bring:

• BS in Computer Science or equivalent experience, 7+ years building products at scale, ideally including platform or infrastructure work.

• Proficiency in TypeScript (preferred) and with at least one of: Go, Java, Kotlin.

• Experience building shared platforms — frameworks, tooling, and CI/CD pipelines. You think in systems, not features. 

• Experience owning the full web release lifecycle, from pipeline design to production delivery.

• Experience designing the data layer between backend services and client apps — GraphQL, BFF patterns, or similar API contracts that keep frontends decoupled.

• Exposure to design systems at scale — building components that product teams actually adopt.

• A track record of onboarding teams onto platforms you built — good docs and APIs that make the right thing the easy thing.

• Nice to have: experience with React Native (performance constraints, native bridge, production-level debugging)
