About The Position

Saga is building a suite of products across the crypto ecosystem â from consumer fintech apps to DeFi protocols and the SagaEVM chain. Our mission is to build products and infrastructure that push the crypto ecosystem forward â whether that's consumer applications, DeFi primitives, or the chains themselves. Our team is world-class â veteran web3 entrepreneurs and builders from Ignite (Tendermint), Apple, Twitter, NVIDIA, and Skuchain â and we're looking to grow as we scale Mino to millions of users. We offer a flexible, remote working environment. You can expect a warm welcome from a friendly and international team that will support you in your personal and professional growth. This is an exciting opportunity to take an active part in the blockchain space and contribute to the decentralization of the future. The Role As a Senior Platform Engineer, you'll own the backend systems and infrastructure that power our products. You'll build the services, APIs, deployment pipelines, and platform tooling that enable a fast-moving product team to ship reliable, performant features to end users.
