Vector Senior Front-end Developer

Senior Front-end Developer

We are a small and ambitious incubated startup developing Vector (, a forward-looking open source collaboration app, and the very first production-ready application built on top of the Matrix open standard.

Vector is built around a few core beliefs we have:

  • anyone should be able to use the app they prefer to communicate, especially in a working environment where things are particularly fragmented between Slack, HipChat, Skype, Lync etc
  • anyone should be able to own their own data
  • messaging apps are the new operating systems for businesses, but that doesn’t mean they should be an overwhelming experience for the user
  • open source software is the greatest way to innovate

Resulting in an app allowing teams to work efficiently as a group by bridging together all their tools and conversation in a simple and uncluttered environment, making it easy to tune in and tune out on every individual’s own terms. Secure, interoperable thanks to the Matrix standard ( and centered around communication (text, voice & video), Vector lets people organise their work by conversations, each of them becoming real virtual teams putting all decisions, files and exchanges on the record, and making them available from anywhere. Vector’s target audience is small teams and working groups, in the future growing to the wider collaboration space.
