About Gnosis Pay

Gnosis Pay is revolutionizing payments, bridging the gap between existing financial rails and decentralized infrastructure, starting with the first self-custodial debit card. We’re bringing web3 to the traditional finance world.

Our first step is enabling smart contract-linked debit cards that work everywhere debit  cards are accepted.
This will allow crypto holders to seamlessly spend their assets in daily life, without needing to cash out through an exchange. Crypto will become a viable payment option for real-world transactions.

Who are we

Our team has deep experience in both traditional payments and decentralized products, like the most popular smart contract wallet Safe, currently securing $50B+ assets. Now we are leveraging that expertise to integrate Web3 and traditional systems in a novel way.

We're a global team united by a bold vision.

While we're distributed, we maintain a tight-knit culture. We look for people who are collaborative, think big, but stay grounded.

Technology
To enable crypto card issuing and payments, we leverage:

• Node.js + TypeScript

• Express

• React / Next.js

• PostgreSQL

• Prisma (ORM)

• Vitest for tests

• Safe / Solidity / Hardhat

• Docker

• AWS (ECS + SSM + RDS) 

There are hard technical challenges around reliability, security and scale. We need talented engineers to help us solve them.
