Salary: $140-180k/year

At Unum ID, we’re building one identity online for each human offline. We provide “sharified” identity: shared, verified identity. Our software links many verifications about a user into one identity that’s shared across companies. This makes knowing who’s who online easy, inexpensive, and secure.

We are a Seed-stage startup founded by brothers out of Stanford and backed by Samsung. We’re a scrappy team of 5 that believe online identity is broken and are on a mission to rebuild it from the ground up. With Unum ID, personal information is decentralized, encrypted behind a biometric, and controlled only by the end user. This eliminates account takeover attacks, severely mitigates data breaches, and reduces verification costs by a factor of 10. It’s hard to state how revolutionary this is.

Do you care about data privacy? Data breaches? Identity theft? This role is for you. Join us today and let’s change the world.
