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: The Cloud Team designs, builds, and operates Remitly’s AWS cloud foundation - the networking fabric and infrastructure tooling that every product team depends on. We manage cloud infrastructure at significant scale (hundreds to thousands of accounts), move money for millions of customers, and treat reliability, security, and operational excellence as non-negotiable. We look for engineers who think in systems, not tickets. This is a hands-on engineering role: alongside infrastructure-as-code, you’ll design, write, and review production Go code. As a Senior Cloud Engineer, you will own deep parts of our cloud and networking stack, contribute to the tooling and services that automate it, and build internal abstractions that reduce cognitive load for the broader engineering org. You Will: Own and evolve our edge infrastructure - CloudFront distributions, AWS Shield, WAF configurations, CDN failover strategies, and latency-optimized routing. Design, build, and maintain the services and CLI tooling (mostly Go) that automate, observe, and extend our cloud platform, using the same engineering practices as product teams: design docs, code review, testing, and production ownership. Monitor and optimize cloud infrastructure costs on an ongoing basis. Lead architecture decisions on cloud topology, multi-account governance, cross-region connectivity, and platform abstractions used by every engineering team. Collaborate with SRE, Security, and Platform teams to embed observability, compliance, and operational excellence into cloud paved pathways. Troubleshoot complex network issues across distributed cloud environments, applying deep knowledge of TCP/IP protocols and traffic flow analysis. Design and operate Remitly’s global partner and bank connectivity network - VPNs (IPSec/IKEv2), Direct Connect, BGP routing to financial partners worldwide, and the broader multi-account, multi-region topology that underlies all of Remitly’s payments infrastructure. Participate in on-call rotation (5-person weekly rotation); occasional late syncs with Seattle (4–6 PM CET). You Have: 5+ years of experience in software, cloud, or infrastructure engineering, including writing production code - with significant hands-on AWS depth. Proficiency in software development for distributed systems with languages such as Go, Python, or similar - you’ve designed, built, and operated production services, not just scripts. Knowledge of cloud networking: VPC design and subnetting, routing, Transit Gateway, DNS, load balancing. Experience with edge infrastructure management: CloudFront distributions, AWS Shield, WAF configurations, and CDN failover strategies. Experience building and operating infrastructure as code (Terraform preferred). Cost optimization skills: AWS billing, Reserved Instances, Savings Plans, right-sizing Understanding of cloud and infrastructure management concepts, including multi-account governance and organizational tooling; Kubernetes/EKS familiarity is a plus.
