About Nexus

The Nexus Project is a scientific and engineering effort bringing truth to the field of computation. We’re enabling bringing to life a new form of compute: verifiable computation, powered by open science and open-source software so it can benefit everyone. Our work aims to bring to life decades of advancements in zero-knowledge cryptography, achieved by many scientists, engineers, and mathematicians, into a single software system.

Nexus raised $25M in Series A funding, co-led by Lightspeed and Pantera, with participation from Dragonfly, SV Angel and more.  

Our team consists of some of the world's top cryptographers, mathematicians, and engineers, all working together with one goal: to unite the world's computers and prove humanity's computations.

We are headquartered in San Francisco, and this role will be in-person, with the rest of the Nexus team.
