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.

Responsibilities: You'll be working on the infrastructure between the legacy payments systems of our partners in the Visa ecosystem and Safe, the world’s leading smart contract wallet that got spun out of Gnosis in 2022. Your job will make sure these two worlds are coherent. We think you'll enjoy this if you're someone who likes to:

  • Think about risk and software architecture

  • Write meticulous unit tests

  • Prefer to focus on high scalability and security 

  • Work with the entire engineering team as well as internal (Metri wallet by Gnosis) and external clients (third party wallets)

  • Use typescript

  • Create observable system

  • Continuously improve the infrastructure and architecture

  • Document systems and share knowledge across teams

  • Monitor and enhance reliability and performance

Who you are
  • You have strong experience with:
    -TypeScript
    -Relational DBs like PostgreSQL or MySQL
    -Any payment systems experience

    Bonus:
    -EVM (solidity + smart contract interaction from a app perspective)
    -Authorization (Visa Base I) and Clearing (Visa Base II) concepts
    -ISO8583

  • Customer obsessed - You always advocate for what's best for the user

  • Systems thinkers - You can understand complex systems and simplify them

  • Love thinking about the best patterns to solve a particular problem

About us

Since launching in 2015, Gnosis has evolved from a prediction market platform into a comprehensive Web3 infrastructure provider. Our journey includes developing Safe, an industry-standard multisig wallet securing over $100 billion in assets, and CoW Protocol, offering MEV-protected decentralized trading. Gnosis also created Zodiac, a modular DAO toolset enabling customizable governance systems. 
In 2021 Gnosis launched the Gnosis Chain through a merger with xDai. This low-cost, reliable L1 supports decentralized applications with high security and uptime.

Today, Gnosis focuses on scaling blockchain technology beyond infrastructure, delivering consumer-facing applications that rival traditional systems in user experience. The ecosystem aims to revolutionize key areas like payments, decentralized AI, and the open web. United by the GNO token, Gnosis's aligned projects work towards a decentralized future where users have greater control and privacy. Gnosis Chain serves as the secure, EVM-compatible foundation supporting this growing ecosystem of innovative products.
Embrace the future of decentralized technology with Gnosis, and join us as we build the open internet together!
