Senior Staff Engineer - Frontend
About Plane
Plane's mission is to build the infrastructure the world's work runs on. We want teams to move faster without losing context, and organizations to retain the flexibility and control they need. Our team is building that work infrastructure as an open, adaptable platform for projects, knowledge, and requests-simple enough for any team to adopt and dependable enough for organizations to build on.
Plane began in public on [GitHub](https://github.com/makeplane/plane) at the end of 2022. Since then, it has grown from an open-source project into a work management platform used by teams around the world. Organizations can use Plane as a managed Cloud service, run it on their own infrastructure, or deploy it inside fully isolated environments. Building in the open keeps us close to users and raises the standard for what we ship.
We believe the future of work will be shaped by people and agents working together. That makes shared context, explicit state, durable history, and accountable action more important-not less. Plane exists to make that future useful, legible, and within the organization's control.
Plane is backed by OSS Capital and built across San Francisco and Hyderabad. We work in small, collaborative teams, stay close to users, and care about both the visible product experience and the unglamorous details that make software dependable. People own problems end to end and add process only when it helps the work.
We are still early. If you want to help define what work infrastructure becomes-and build software that teams can make their own and organizations can depend on-we'd like to hear from you.
