Technical Lead

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.

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.
