Senior Full Stack Developer

Unum ID

San Francisco



Job Type: Full-time

Salary: $125-$175k per year

At Unum ID, we’re building a single 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 and Draper Associates. We’re a scrappy team that believes 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.
