Senior Engineer, Solana

As a Senior Engineer at R3, you build and ship production RWA trading and lending infrastructure on Solana. You work across the full stack, from on-chain programs to the front ends that investors, traders, and integrators use. You'll be working on systems that move real capital: liquidity venues, lending markets, and market-making infrastructure. As an early team member, you shape the Corda Protocol, an institutional tokenized Real World Asset platform built on Solana that bridges traditional finance and DeFi.

What you'll do

• Influence the design and development of the Corda Protocol RWA yield marketplace to scale it to a multichain, multi-curator future
• Build the full stack around Solana programs: indexers, keepers/crankers, APIs, and React/TypeScript front ends that expose them to users and integrators
• Design and build Solana programs in Rust/Anchor for vaults, lending markets, and related liquidity infrastructure
• Work directly on market-making and liquidity systems and the infrastructure that keeps venues liquid and solvent
• Participate in code review, threat modelling, and internal/external audits of new and existing programs
• Design, implement, and optimize SDKs that power integration with centralized partners such as exchanges, wallets, and neobanks

What you bring

• Prior experience at a crypto-native or web3 engineering team, including work at a lending protocol, yield marketplace, vaults infrastructure, or similar marketplace connecting on-chain allocators to curated vaults
• Minimum 6 years in software development and 2 years of meaningful production experience with Rust on Solana
• Proven experience shipping and deploying Solana programs in Rust (Anchor or native), ideally in order book or AMM-style liquidity venues, lending/borrowing protocols, or market-making systems
• Full stack capability: comfortable owning on-chain program logic and the off-chain services and front end (TypeScript/React, Node) that surround it
• A solid understanding of Solana's account model, PDAs, CPI, transaction/compute limits, and the tradeoffs involved in high-throughput on-chain systems
• A genuine interest in bringing regulated finance on-chain and a track record of shipping DeFi protocols on Solana with understanding of the operational realities of running them under load

Nice to have

• Experience owning architecture and delivery
• MPC wallets, custody, Squads, on-chain monitoring, and AML screening
• Familiarity with Kubernetes concepts, Kubernetes networking, Terraform, and PostgreSQL
• PKI and other cryptographic knowledge
• Experience supporting systems in production and investigating and diagnosing issues for internal or external customers
• Experience with Linux, shell scripting or other scripting languages, Linux command line tools, and TCP/IP networking
• Java or Kotlin

About R3

R3 is building the on-ramp for the next trillion dollars of assets to move on-chain, bridging traditional finance and DeFi. The Corda Protocol is an institutional tokenized Real World Asset platform built on Solana, where KYC'd investors deposit stablecoins into RWA vaults in exchange for vault tokens that they can redeem back into stablecoins.
