Financial Services Seoul 51–200 employees Founded 2015 Privately Held

SentBe operates a cross-border payments infrastructure serving both individual remitters and businesses, with a tech stack anchored in Go, Spring, PostgreSQL, and AWS Kubernetes. The company is actively migrating from monolith to microservices while adopting Java and replacing Go — a significant architectural shift that, combined with simultaneous multi-cloud expansion (AWS + Azure) and infrastructure automation projects, suggests they're moving from a tightly coupled legacy system toward distributed, scalable payment processing. Hiring velocity is accelerating across engineering and leadership, with management-level openings matching the complexity of ongoing infrastructure transformation.
