Overview

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. We encourage 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 todays and tomorrow’s world financial system. You’ll be part of our multidisciplinary engineering team, where you will build and evolve our Corda Distributed Ledger Technology, powering private enterprises, networks and the Solana public blockchain.

The team is focussed on building out integration of Corda with the high-performance Solana public blockchain to enable interoperability both among multiple Corda private networks and between Corda and the Solana public network.

You will bring engineering knowledge and experience of on-chain programming of Solana in Rust. This project is accessing Solana from server infrastructure written in Kotlin and does not have a web UI or TypeScript element.

Responsibilities

• You will design, implement and test Solana on-chain programs, written in Rust.
• Bring Solana on-chain knowledge, best practices, experience and idiomatic thinking to bear on the architecture, design and implementation of the Corda / Solana integration.
• Leverage the Solana existing ecosystem and community to accelerate implementation and delivery.
• You will contribute to the technical direction of Solana engineering at R3.
• You will mentor and assist other engineers, enabling them to understand your approach to understanding and solving problems, and help them upskill and thrive in the Solana on-chain ecosystem.
• You will learn, understand and develop Corda, R3’s private DLT product.
• You will use developed and comprehensive judgment to make decisions of complexity.
• Maintaining a security focussed adversarial mindset during design and development, working with our internal security team and security audit vendors.
• Collaborate with fellow engineers within the team and organisation by developing technical plans and contributing to technical architecture.
• You will hone your business analysis skills to interact with the product management team to marry technical delivery and product requirements.
• You will develop customer focus skills to anticipate internal/external customer requests.

Required Skills

• In-depth knowledge of the Solana ecosystem, Solana clients & programs, pain points and anti-patterns.
• Expertise in Rust programming language.
• Strong understanding of Solana Account Model, Program Derived Addresses and Cross Program Invocation.

• In-depth knowledge of Solana RPC clients.
• Understanding of blockchain architecture, consensus mechanisms, and distributed systems.
• Knowledge of cryptographic concepts (public/private keys, digital signatures, hashing).
• Experience in software engineering roles.
• Excellent problem-solving, critical thinking, and decision-making abilities.
• Experience collaborating effectively in a cross-disciplinary team setup interacting directly with many parts of the organisation.
• A positive, cheerful, can-do attitude where obstacles are just problems yet to be solved.

Nice to Have

• Experience with ZK Compression / Light Protocol / Photon Indexer.
• Experience with Pinocchio and zero copy.
• In-depth knowledge of Solana validators, consensus, confirmation and finality.
• Interest in Alpenglow and the advances this will bring to latency and finality.
• Solana program optimisation.
• Experience working with Solana security audit review vendors.
• Experience of Linux, shell scripting or other scripting languages, Linux command line tools, TCP/IP networking.
• Corda knowledge / experience.
• Another DLT or public blockchain besides Solana.
• Familiarity and /or experience with Kotlin.
• Any Java or JVM ecosystem experience.
• Other high level programming languages such as C#, C++, Objective-C, Swift.
