Job Description
Summary
Role Summary
We are seeking a smart contract and DLT engineer to lead the technical development of a prototype clearing and settlement engine for GBP-denominated stablecoins. This sub-contracted, short-term UK-based role will focus on building a permissioned Ethereum-based proof-of-concept (PoC) for atomic Delivery-versus-Payment (DvP) and Delivery-versus-Delivery (DvD) functionality using modular smart contracts. You will work closely with the founding team to design, build, and test the core architecture underpinning a regulated digital settlement platform.
Duties / Responsibilities
- Design and implement smart contracts for DvP/DvD settlement using Solidity (or Vyper)
- Integrate tokenised GBP stablecoin mockups and ERC-20 representations of financial assets
- Build access-controlled modules for participant whitelisting and role-based functions
- Develop a local testnet simulation for multi-party transaction settlement scenarios
- Create basic user interfaces and API hooks for instruction submission and reconciliation
- Document system logic, interfaces, and testing procedures for internal and regulatory review
Required Skills
- Proficiency in Solidity, Ethereum smart contract development, and DLT design patterns
- Strong understanding of atomic settlement mechanisms, particularly DvP and DvD
- Experience with Truffle, Hardhat, Ganache, or similar smart contract development tools
- Familiarity with access control frameworks, multisig wallets, and EIP standards
- Ability to work independently in a startup/prototype environment, under fast-paced timelines
Education and Experience
- Bachelor’s degree or higher in Computer Science, Engineering, or equivalent
- 2–5 years of experience in blockchain development, with at least one deployed PoC or pilot
- Prior exposure to financial infrastructure or stablecoins is a strong plus
- Experience working with startups, innovation labs, or regulated fintech projects preferred
Additional Requirements or Expectations Specific to the Position
- Sub-contract position; up to 5 months , with possible extension
- UK-based candidates only — right to work in the UK is required
- Remote, with weekly virtual team check-ins and milestone-based reporting
- Occasional in-person meetings in London may be required (reasonable travel costs covered)
- Candidate must be able to deliver production-quality prototypes with minimal supervision
Skills
- Smart Contract Development
- Solidity
