Help stop fake and disposable emails at the source.
OpenGuardian is a small, remote-friendly team building the verification layer that sits in front of millions of signup forms. We are looking for people who care about getting an edge case right, not just shipping a feature that mostly works.
How we work
- • Remote-first, async by default, with a few overlapping hours for live discussion.
- • Small team — every engineer talks directly to customers, not just to a product manager relaying feedback.
- • We ship in small, verifiable increments — the same philosophy as the product itself.
