R3 Labs is a newly formed R3 unit with a collaboration with Solana. Our goal is to be the on-ramp for the next $1Tn of assets on-chain and we are focused on enabling financial institutions and asset originators to issue, manage and put to work real-world assets (RWA) on-chain. We combine the security, compliance, and enterprise know-how of R3 with the speed and composability of next-gen blockchain networks. We’re building the solutions for diverse on-chain assets, from funds and securities to carbon credits and real estate - with composability and interoperability at the core.

The Role:

We’re looking for a Lead Solutions Engineer with strong Web3 exposure to lead technical solution design and delivery for our clients and partners. You’ll serve as a bridge between product, engineering, and enterprise clients, helping define and implement RWA tokenization strategies on Solana and adjacent ecosystems. While you’ll work within a Solana-first environment, most of your contributions will be in architectural design, APIs, smart contract integrations, data pipelines, and compliance flows rather than low-level Rust development (though familiarity is a plus).

What you'll do:

  • Design tokenization architectures for RWAs on Solana as well as custody, compliance, and lifecycle flows
  • Interface with enterprise clients and partners to understand technical requirements
  • Develop integration blueprints across APIs, smart contracts (Solana + SPL), oracles, and custodians
  • Collaborate with protocol developers, external front-end and back-end teams to deliver E2E solutions
  • Contribute to reference architectures and internal best practices for compliant asset issuance
  • Stay up to date on Solana improvement proposals, DeFi infrastructure, and regulatory developments

You might be a fit if you have:

  • 8+ years in a technical architecture or engineering role
  • Hands-on experience with Web3 tools: wallets, APIs, smart contracts (ideally Solana)
  • Solid understanding of asset tokenization (e.g. securities, funds, carbon, real estate)
  • Familiarity with Solana architecture (SPL tokens, PDAs, anchor framework, etc.)
  • Prior exposure to regulated financial institutions or capital markets infrastructure
  • Bonus: Experience with enterprise integrations, custody APIs, or compliance toolkits
  • Nice to have: Rust reading fluency (writing not required); experience on Ethereum or Cosmos

Why join R3 Labs?

  • Work at the intersection of Web3 innovation and institutional-grade infrastructure
  • Influence how the next generation of tokenized assets is built and traded
