About Gnosis
GnosisDAO builds decentralized infrastructure for the Ethereum ecosystem. In November 2021, the xDAI and GnosisDAO communities voted to combine their vibrant ecosystems to create the Gnosis Chain: An Ethereum forerunner-companion that addresses scaling issues through solid engineering. Gnosis Chain is the associated execution-layer EVM chain for stable transactions. It uses the xDai token and includes a wide-ranging group of projects and users. The Gnosis mission has always been centered on experimentation and building decentralized infrastructure for the Ethereum ecosystem. When Gnosis was founded in 2015, it focused on building prediction markets to enable worldwide access to accurate information. While creating the prediction market platform, it became clear that Gnosis needed to build the infrastructure required to support it. As a DAO, Gnosis uses the products that it creates to transparently guide decisions on the development, support, and governance of its ecosystem. Gnosis Safe (multisig and programmable account), Cow Protocol (formerly CowSwap and Gnosis Protocol), Conditional Tokens (prediction markets), Gnosis Auction, and Zodiac (standard and tooling for composable DAOs) are all products incubated by Gnosis. Their success can be demonstrated by the recent spin-out of Cow Protocol and the formation of SafeDAO. By combining needs-driven development with deep technical expertise, Gnosis has built the decentralized infrastructure for the Ethereum ecosystem.

Job description

What you will do

Location: Remote 

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

  • Masters of their craft - You relentlessly hone your skills and learn new ones

  • Personal Development: Pursue your professional goals with our support, including personal education budgets and conference allowances. We invest in your growth and learning.
  • Innovation and Experimentation: Interested in exploring new ideas? Dedicate your Friday afternoons to research or work on a side project within our ecosystem. We encourage creativity and experimentation.

  • Flexible and Remote Work: Not a morning person? No problem! We embrace flexible working schedules and have a long-standing culture of remote work. Balance your professional and personal life in a way that works for you.
  • State-of-the-Art Equipment: Receive the latest hardware and all the tools you need. We make sure you're well-equipped to do your best work.
