Integration Engineer, AgeKeys

OpenAge is a public interest initiative rethinking how age is established online. Our mission is simple: protect digital youth from harm while preserving the privacy and freedom of adults.

At the center of OpenAge is AgeKey, a reusable, passkey based age credential that enables age checks without identity disclosure. AgeKey allows platforms to verify age in a privacy preserving way, giving users control while reducing friction and compliance risk.

OpenAge operates as a neutral, interoperable layer rather than a closed ecosystem. We work with a broad set of verification and identity partners, including Socure, Persona, Incode, and Veratad. More than 5 million age verifications have been completed during our beta phase.

We are a small, senior team building foundational digital infrastructure with global regulatory relevance. We treat safety, privacy, and usability as design requirements, not trade offs.

OpenAge is incubated within k-ID, the global leader in privacy first compliance and age assurance infrastructure. k-ID has been recognized as one of TIME's Best Inventions and as a World Economic Forum Tech Pioneer. OpenAge operates as a division of k-ID with independent governance and advisory oversight to ensure transparency, neutrality, and accountability.
