We’re looking for a Senior Golang Developer to join the team responsible for B2B client integrations with our API. The core of the role is simple: when partners have technical questions, they should be speaking directly with someone who can understand and resolve them — not waiting for a relay between teams. You’ll work directly with partner engineering teams on API behavior, architecture, edge cases, and integration flows. This includes hands-on backend work in Go, ownership of parts of the public API, and active participation in solving real integration and production issues.
