Software Developer, Cryptography & Full-Stack

What you’ll do

• Work on our authentication protocol, including replay/relay resistance and key handling
• Integrate with identity providers via OIDC and WebAuthn/passkeys. One Identity today, with Okta and Microsoft Entra on the roadmap
• Contribute to our offline peer-to-peer authentication and its cryptographic protocol
• Help keep everything secure and scalable as we grow

What we’re looking for
