JetKVM, by BuildJet, Inc. (backed by Y Combinator W23), is a hardware/software project redefining what remote server access can be. We built a full KVM-over-IP device that lets users control any machine - BIOS and all - directly through a browser. After a record-breaking Kickstarter campaign, JetKVM became the third most-backed technology project on Kickstarter of all time, raising over $6M on our Kickstarter. Today, we're scaling production, firmware, and cloud services to support tens of thousands of users worldwide. Our open-source software stack spans wide, a Node & Go backend and a React frontend - with WebRTC, hardware encoding, and cloud API all in the mix. Everything we build is open-source and aims for performance, clarity, and maintainability github.com/jetkvm, JetKVM is still small, so your impact will be huge. You'll work on a technically challenging product used by engineers around the world. You'll be part of an open, pragmatic team that values autonomy, quality, and shipping things that last.
