Software Engineer

Plane's mission is to build the infrastructure the world's work runs on. Every organization runs on three things: the projects it's driving, the knowledge it keeps, and the requests it fields. Plane brings all three into one open, adaptable platform: simple enough for any team to adopt, dependable enough for organizations to build on. And we are building it for a future where humans and AI agents do that work together.

Plane began in public on GitHub at the end of 2022. Since then it has grown into a work management platform used by teams around the world: 55,000+ stars, 5,000+ forks, and a contributor community that reads our code and files our issues. Organizations run Plane as a managed Cloud service, on their own infrastructure, or inside fully isolated environments. Building in the open keeps us close to users and raises the standard for everything we ship.

Plane is the #1 work infrastructure in aerospace, defense, financial services, and other regulated industries: organizations whose requirements for control, auditability, and data residency rule most software out. When the strictest buyers pick a system of record, that choice means something. Adoption is growing fastest on Plane Cloud and in sovereign clouds, deployments that keep everything inside a country's own borders and rules.

Plane is backed by top investors and built across San Francisco, London, and Hyderabad. We work in tightly knit teams, stay close to users, and care about the visible product as much as the unglamorous details that make software dependable. People own problems end to end, and we add process only when it helps the work.

• Own user-facing surfaces from design review through component work to rollout, starting with scoped ones and taking on larger ones as you learn the client.
• Extend the local-first sync and collaborative editing layer alongside the engineers who built it: serialization, conflict resolution, and what the interface does when the two disagree.
• Keep dense views fast. Virtualization, memoization, and render paths in workspaces holding tens of thousands of issues are yours to profile and fix.
• Make Plane usable offline and on slow networks with Service Workers and IndexedDB, including for customers whose machines never reach the internet.
• Work daily with designers and backend engineers across San Francisco and Hyderabad, and review community pull requests from contributors you will never meet.
• Chase visual and behavioral bugs you cannot reproduce, across browsers, screen sizes, and self-hosted versions running months behind ours.

• You have shipped React and TypeScript to production. Point us to something you built, and tell us one decision in it you would make differently now.
• You reason about state, not just hooks. You know when state belongs local, when it belongs global, and how reactivity moves through an app (MobX, Redux, Zustand, or similar).
• You write CSS with intent. Responsive, themeable interfaces in Tailwind or a comparable system, and an eye that catches a misaligned element before review does.
• You have worked inside a shared component library. You know what breaks when a component is used in ways its author did not plan for.

Nice to haves:

• You have made a slow interface fast, and you can quote the measurement.
• You have contributed to Plane, run it self-hosted, or maintained another open project people rely on.
• You have worked inside a rich-text editor framework (ProseMirror, CodeMirror, Lexical, Tiptap) rather than only on top of one.
• You have built offline-first or CRDT-backed applications and have opinions about conflict resolution.
• You have built interfaces where AI agents act on real data, and you have thought about how to show authorship and authority.

• Work in tightly knit teams, stay close to users, and care about the visible product as much as the unglamorous details that make software dependable.
• People own problems end to end, and we add process only when it helps the work.
• Backed by top investors and built across San Francisco, London, and Hyderabad.
