About Pocket

We’re a remote-first team. Video conferencing, Slack chats, and shared documents keep everyone in the loop and make sure no one feels isolated. We value transparency and collaboration from the CEO on down.

As a subsidiary of Mozilla, we have the nimbleness of a small team with the resources of a large company, which means each teammate has the opportunity to make a big impact. But we make sure our working hours are flexible—not just because we have team members in different time zones—but because we know you have a life outside the office, and we value that. You’re human, we’re human, and everyone at Pocket is treated with utmost respect.
