At R3, we are building the on-ramp for the next trillion dollars of assets to move on-chain, bridging the worlds of traditional finance (TradFi) and decentralized finance (DeFi). We are launching institutional-grade RWA yield vaults, fully composable and integrated into Solana DeFi.
Our Corda Protocol is an institutional tokenized Real World Asset platform built on Solana. KYC'd investors deposit stablecoins into RWA vaults in exchange for vault tokens, and redeem the oracle-priced vault tokens back into stablecoins, with curators buying and selling the corresponding assets out in the Real World to settle those on-chain token transactions.
The Role
We're looking for a Senior Full Stack Engineer to build and ship production RWA trading and lending infrastructure on Solana. You'll work across the stack, from on-chain programs to the front ends investors, traders and integrators use. You'll be working on systems that move real capital: liquidity venues, lending markets, and market-making infrastructure. This is a hands-on role for someone who has a genuine interest in bringing regulated finance on-chain and has already shipped DeFi protocols on Solana and understands the operational realities of running them under load.
As an early team member, you will play a crucial role in shaping the Corda Protocol. You should care as much about security, compliance, and auditability as you do about shipping quickly.
Responsibilities
• Influence the design and development of the Corda Protocol RWA yield marketplace to scale it to multichain & multi-curator future
• Design and build Solana programs (Rust/Anchor) for vaults, order books, AMMs, lending markets, or related liquidity infrastructure.
• Build the full stack around these programs: indexers, keepers/crankers, APIs, and the React/TypeScript front ends that expose them to users and integrators.
• Work directly on market-making and liquidity systems and the plumbing 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 will power our integration with centralized partners (exchanges, wallets, neobanks).
Required Skills/Experience
• Prior experience at a crypto-native or web3 engineering team is a must; you will have worked at a lending protocol, yield marketplace, vaults infra or any similar marketplace that connected onchain allocators to the curated vaults.
• Minimum of 6 years in software development and 2 years of experience in Rust with meaningful production time on Solana.
• Proven experience shipping and deploying Solana programs in Rust (Anchor or native), ideally in one or more of: order book or AMM->
• Full stack range: comfortable owning on-chain program logic and the off-chain services and front end (TypeScript/React, Node) that surround it.
• Solid understanding of Solana's account model, PDAs, CPI, transaction/compute limits, and the tradeoffs involved in high-throughput on-chain systems.
Nice to Haves
• Experience owning architecture & delivery.
• MPC wallets/custody, Squads, on-chain monitoring, AML screening.
• Familiarity with Kubernetes concepts & Kubernetes networking, Terraform, PostgreSQL.
• PKI and other cryptographic knowledge.
• Experience supporting systems in production and investigating & diagnosing issues for internal or external customers.
• Experience of Linux, shell scripting or other scripting languages, Linux command line tools, TCP/IP networking.
• Java / Kotlin.
Is Kotlin a good career?
Yes, Kotlin is a good career choice for developers who want to work in the Android app development, backend development, or cross-platform development space
Kotlin is a modern programming language that was designed to improve upon some of the shortcomings of Java, making it more concise, safe, and interoperable with other languages
Here are some reasons why Kotlin is a good career choice:
- High Demand: Kotlin is in high demand in the technology industry, especially in the Android app development space. Many companies are now using Kotlin to develop their Android apps, and the demand for Kotlin developers is growing rapidly.
- Compatibility: Kotlin is interoperable with Java, which means that developers can use both languages in the same project. This makes it easy for developers to migrate from Java to Kotlin and vice versa, and it also makes it easier to integrate Kotlin into existing Java-based projects.
- Easy to Learn: Kotlin is relatively easy to learn for developers who are already familiar with Java or other similar programming languages. Kotlin has a simpler syntax than Java, making it easier to read and write code.
- Concise and Safe: Kotlin is a more concise language than Java, which means that developers can write less code to achieve the same functionality. Additionally, Kotlin has built-in null safety features that help developers avoid common errors and bugs.
- Career Growth: Kotlin is a relatively new language, which means that there is a lot of room for growth and innovation. Developers who are proficient in Kotlin have the opportunity to contribute to the development of the language and its ecosystem, which can lead to career growth and advancement.
