We're looking for a hands-on Blockchain/DLT Developer to join a growing technology team building distributed ledger solutions for financial services.

The key requirement - this is primarily a private/permissioned DLT role.

We're looking for someone who has genuine hands-on experience building and deploying enterprise or permissioned blockchain solutions - not solely public-chain/Web3 experience.

You'll work across a combination of permissioned DLT, smart contracts and public-chain technologies, helping develop a proprietary enterprise blockchain platform and its surrounding applications.

What you'll do

• Build and deploy private/permissioned DLT and smart contract solutions.

• Develop blockchain applications for financial services, digital assets and capital markets.

• Contribute to a proprietary enterprise blockchain platform, including protocol and tooling development.

• Integrate DLT with APIs, Back End services and wider platform infrastructure.

• Work with technologies including Ethereum, Hedera, Algorand and enterprise DLT.

• Build, test and optimise secure smart contracts.

• Collaborate with architects, engineers, product teams and clients.

What we're looking for

• Hands-on private/permissioned/enterprise DLT experience - eg Hyperledger Fabric, Besu, Corda, Quorum or similar.

• Strong blockchain fundamentals across consensus, cryptography, tokenisation and DLT architecture.

• Experience with Solidity/Ethereum smart contracts.

• Experience with security tokens, digital assets or tokenisation.

• Strong development skills in Go, Java, Python or Node.js.

• Experience with Web3.js, Ethers.js, Hardhat, Foundry or equivalent tooling.

• Ideally, experience across financial services, capital markets or fintech.
