Careers

Build the messenger the future can't break.

TalkOnce is a small, senior team building post-quantum end-to-end encryption that real people can actually use. If protecting privacy is the work you want to do, we'd love to hear from you.

What we care about

• Cryptography and security engineering done to the highest standard — no shortcuts, independently auditable.
• Beautiful, fast, human software (iOS / Flutter) that never leaks what it's protecting.
• Radical honesty about what we can and can't promise our users.

Areas we're always glad to meet people in

• Applied cryptography & protocol engineering
• iOS / Flutter client engineering
• Backend, infrastructure & security
• Design & product
