Web3 Solutions Architect

r3 • Full-time • London • 1m ago

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
