Web3 Full Stack Engineer

Multis is hiring!


We believe crypto is the future of business, and that the wave of new web3 organizations and DAOs formed today will be an increasing share of our economy. Our insight is simple: as these organizations scale and become the new business norm, they need crypto-native solutions to help them with basic financial operations, so they can focus on their business.

The current state of financial tooling is appalling. It's still insanely hard to make crypto transactions, monitor cashflows, or simply swap crypto with USD and EUR. These organizations have no control nor visibility over their crypto finances — they know things will fall apart.

So we created Multis. Our mission is to build the financial backbone of web3 organizations and empower them to build a better Web.

Today, Multis is an all-in-one crypto management app designed to help web3 organizations feel confident and in control of their crypto finances. We help them automate payments in crypto and USD, monitor cashflows in real time and close their books 5x faster.
