Backend Engineer: Senior, Staff, & Principal

At Flowhub, we’re on a mission to make safe, legal cannabis accessible to everyone. As one of the first cannabis technology companies, we helped shape the industry by launching the first Metrc API integration, empowering dispensaries to stay compliant with complex state regulations. Today, Flowhub powers over 1,000 cannabis retailers across the U.S., supporting more than $3 billion in annual sales. Our flagship product, Flowhub Maui, is a modern point-of-sale and retail management platform built to help cannabis businesses thrive—by making daily operations easier, inventory traceable, and compliance effortless.

We're a passionate, mission-driven team that believes technology can break down barriers, expand access, and create a better cannabis experience for everyone. We value inclusivity, transparency, and a deep commitment to building tools that make a difference.

We’re looking for senior, staff, and principal Backend Engineers to join our product engineering team and help scale Flowhub Maui, our next-gen retail platform. You’ll be part of a collaborative squad that ships well-tested, performant microservices in a modern cloud-native environment.

Our stack includes Go, Kubernetes, PostgreSQL, gRPC, and GCP—and we value clean architecture, observability, and continuous delivery.

This is a hands-on, high-impact role where your work will directly support cannabis retailers, helping them operate more efficiently, stay compliant, and serve their customers better.
