Corda Solana On-Chain Rust Engineer

At R3, our vision is a world where value moves freely, and business is done safely. Our mission is to enable an open, trusted, and enduring digital economy. We are a scale-up with a startup's grit, encouraging a workforce where no idea is too small, and no two days are the same. At R3, you will work at, and help define, the exciting convergence point between TradFi (Traditional Finance) and DeFi (Decentralised Finance). You are a Software Engineer with a product mindset and will be building platforms for today's and tomorrow's financial systems. You'll be part of our multidisciplinary engineering team, building and evolving our Corda Distributed Ledger Technology, powering private enterprises, networks, and the Solana public blockchain. The team focuses on integrating Corda with the high-performance Solana public blockchain to enable interoperability among multiple Corda private networks and between Corda and Solana. You will bring engineering knowledge and experience in on-chain programming of Solana in Rust. This project involves accessing Solana from server infrastructure written in Kotlin, with no web UI or Typescript components. Responsibilities
