We've grown fast, stayed lean, and secured our place as a leader in the industry.
If you have excellent English communication skills and are ready to contribute to the most innovative platform on the planet, Tether is the place for you.
At Holepunch, we're building a peer-to-peer platform for apps that don't need servers at all. Users connect directly, which means they keep full control of their data and their conversations stay private by design. We believe the internet should be peer-to-peer by default, and Keet, our P2P video call and chat app, is how we're showing the world what that looks like.
Keet runs on Pear Runtime and our open-source stack (Hypercore, Hyperswarm, Hyperdrive), which handles everything from peer discovery and NAT traversal to data replication and end-to-end encryption.
The Keet engine team works on the core that makes Keet tick: connecting peers, replicating data, syncing rooms, and keeping calls and file transfers fast and reliable across every kind of network. We're looking for an organized, curious Junior Project Manager to help keep that work moving.
You'll work closely with a globally distributed team of senior engineers, help turn priorities into clear plans, and make sure nothing falls through the cracks between releases. This is a great role for someone early in their career who wants to grow into technical project or product management in a deeply technical, open-source environment.
Track engine work across sprints and releases, keeping issues, milestones, and roadmaps current
Run or support stand-ups, planning sessions, and retrospectives across time zones (mostly async)
Coordinate between the engine team, Keet app/UI developers, and QA so dependencies are visible early
Write clear status updates, release notes, and meeting summaries
Help triage bug reports and user feedback, and route them to the right engineers
Spot risks and blockers early and help the team resolve them
Keep internal documentation and processes tidy and easy to follow
