About the role
In the Global Bank tribe , we're building the infrastructure to provide merchants with a digital business account that empowers them to manage their banking needs. Our goal is to become the most popular banking partner for small merchants globally with an effortless, simple, and affordable experience. You'll help us transition from fragmented regional setups to a unified global infrastructure, directly enabling millions of merchants worldwide to access seamless banking tailored to their needs. As a Senior Backend Engineer on the Global Accounts team, you'll own critical pieces of our bank account platform. You'll help us design and build a fully distributed, event-driven system designed to scale across regions with resilience and compliance built in. You'll work primarily in Kotlin, with opportunities in Elixir and Golang. We practice Extreme Programming: small iterations, daily deliveries, and a focus on technical design quality and deep problem understanding. Our tech stack includes Kotlin, Golang, Elixir, Java, AWS, Kafka, PostgreSQL, and Kubernetes, supported by observability tools like Prometheus, Grafana, and Honeycomb. We also use AI-assisted development tools including Cursor and GitHub Copilot. What You'll Do Build critical infrastructure from scratch: Contribute to the design and implementation of a newly architected global accounts platform. You'll help migrate existing systems to a modern, event-driven, decoupled architecture that enables scalability and resilience across regions. Master event-driven architecture: You'll be working extensively with Kafka to build a truly decoupled, resilient system. Event-driven architecture is essential to our goal of ensuring that failures in one part of the system don't bring down banking operations globally. This isn't just a technical requirement—it's the foundation of building a platform that can handle the complexities of multi-region banking. Solve complex compliance challenges: Design flexible systems that handle varying regulatory and verification requirements across different regions and use cases. You'll make compliance requirements maintainable and natural rather than an afterthought. Enable other teams: Build a self-service platform that empowers internal teams across the organization to contribute to and build on top of. Work globally: Your work will directly impact EU and LATAM markets, with potential US expansion on the horizon. You'll Be Great for This Role If Strong technical foundation: Solid backend development experience in Kotlin , with interest in working across multiple languages (Golang, Elixir). You understand system architecture, object-oriented and functional design principles, data modeling, and API design (RESTful and event-driven). Event-driven architecture expertise: Proven experience with Kafka and event-driven systems. You understand how this enables true decoupling and resilience in distributed systems. Distributed systems mastery: You've built tested, observable, s
