What You’ll Do
As a software engineer at Multis, you will work with our Product and Design team to define the outcomes and success metrics for the next features prioritized in the roadmap. You will own the build from front-to-back and start-to-finish, designing with security and quality in a timely manner to continuously push to deliver value to our users.
More concretely, you will have the opportunity to work and leave your mark on existing and new functionalities across the application:
  • Integrate, via our Banking partner, a business USD account, plugged with a crypto exchange to allow organizations to swap between USD and Cryptos
  • Participate in the constant improvement of our analytics layer, collecting more on-chain and off-chain data across multiple Blockchain and services.
  • Expand our payment system to Layer2 and alternative Layer1 and integrate selected DeFi protocols into the app
  • Ensure every component can scale over time


For the past few years, cryptos and blockchain technologies have been taking off like crazy. Though it is still pretty recent and most of the tools that exist on the market today are only suitable for individuals, not businesses.

So we created Multis.

Our mission is to support future generations of entrepreneurs, businesses, and organizations (DAOs, Web3, NFTs, Metaverse) in their growth by creating their financial backbone.

We offer an all-in-one app for web3 companies to manage their cryptos on a daily basis with cashflow monitoring and reporting tools as well as the possibility to make payments using cryptos (salaries, invoices, etc) or make exchanges in both crypto and fiat currencies.
We are a founding team of happy and passionate crypto-dreamers: Thibaut (CEO) and Théo (CTO), with backing from world-class US and European investors like Y Combinator, Coinbase Ventures and eFounders. The company is incorporated in San Francisco but They’re working from Paris and Europe for now.

What’s so special about engineering at Multis?
Multis engineering is working at the cutting edge of FinTech, Blockchain, and Web3 technologies with incredible challenges ahead, that includes supporting multiple blockchain networks, integrating with financial and banking third-party APIs, and transitioning parts of our stack to NodeJS.
You will be part of a small development team at an early-stage startup in a fast-moving industry with a focus on delivery speed, high work standards, and team spirit!
