Emerald

We build a cryptocurrency wallet and an infrastructure to connect businesses with blockchain. We are looking for a backend engineer to join the team. On backend, we primarily use Java and Kotlin and build a fault-tolerant global API for blockchain. We also actively contribute to the industry with several Open Source projects. Also interested in JS and Rust engineers. We have challenging tech problems (blockchain stack and protocols, global fault-tolerant infra, security, and crypto), fully remote work, disrupting the global financial system, and building for real users, not 'crypto investors'. Tech stack: Java, Kotlin, Spring & Spring Reactor, Google Cloud with Apache Beam, HBase, Kubernetes, PubSub, etc.
