What you will do

About Gnosis Pay
Gnosis Pay provides the API and card-program infrastructure that enables wallets, fintechs, and businesses to issue stablecoin-powered payment cards and create custom payment flows. Partners can easily connect on-chain wallets to real-world spending.

With our technology, users can spend stablecoins directly from their on-chain wallet using a Visa debit card. Transactions are executed through a secure smart-wallet rather than a traditional bank account, allowing users to retain full custody of their assets while paying anywhere Visa is accepted.

About the role and team 
We build the infrastructure that bridges traditional financial rails and crypto, enabling new financial products and seamless integrations. Our goal is to provide a secure, scalable, and developer-friendly platform that powers both internal product teams and external partners.

We are seeking a seasoned Tech Lead to drive the technical direction and execution for core services within Gnosis Pay. This role is a unique opportunity to shape the performance and scalability of a groundbreaking Web3 infrastructure that bridges self-custodial crypto assets with global Visa acceptance. You will lead by example, mentoring engineers and playing a crucial, hands-on role.
