Senior DLT / Smart Contract Engineering Lead (Capital Markets & Banking)
Lead the design and delivery of enterprise grade blockchain solutions within regulated financial environments. This role focuses on smart contract engineering, tokenised securities, digital cash integration, and secure, compliant DLT platforms for capital markets, payments, and settlement systems.
Hybrid Working
The places that you work from day to day will vary according to your role, your needs, and those of the business; it will be a blend of Company offices, client sites, and your home; noting that you will be unable to work at home 100% of the time.
Blockchain & Solution Delivery
- Design and implement distributed ledger solutions for capital markets, payments, custody and settlement systems.
- Deliver production grade blockchain systems for banks, Financial Market Infrastructures (FMIs), exchanges and regulated fintechs.
- Integrate on chain logic with off chain enterprise systems, including core banking platforms, Central Securities Depositories (CSDs), payment rails and regulatory reporting systems.
Smart Contract Engineering
- Develop, test, audit, and deploy secure Solidity based smart contracts.
- Implement advanced contract logic for asset issuance, transfer, redemption, lifecycle event management and settlement workflows (DvP, escrow, atomic swaps).
- Design and implement token standards (fungible, NFT, hybrid securities), gas optimised architectures and upgradeable contract patterns.
Tokenisation & Digital Cash
- Build and manage tokenisation frameworks for securities and financial instruments, tokenised assets across lifecycle stages, stablecoins, tokenised bank deposits and on chain cash leg representations for DvP.
- Ensure compliance with regulatory requirements for on chain financial products.
Blockchain Platforms & Standards
- Work across public and permissioned DLT platforms: Ethereum, Hyperledger Besu, Corda.
- Apply enterprise blockchain standards for privacy, interoperability and tokenised securities markets.
Security, Custody & Cryptography
- Ensure secure smart contract design by addressing reentrancy attacks, access control vulnerabilities and precision/overflow issues.
- Design custody and wallet solutions using MPC (Multi Party Computation), HSM backed signing and policy based wallet controls.
- Implement privacy preserving mechanisms: permissioned access models, selective disclosure and zero knowledge proof concepts.
Cloud, DevOps & Engineering Excellence
- Build and deploy cloud native applications on AWS, Azure or GCP.
- Operate containerised systems using Kubernetes and microservices architectures.
- Implement DevSecOps practices: CI/CD pipelines for smart contracts and backend services, automated testing and security scanning and Infrastructure as Code.
- Ensure production reliability through monitoring (Prometheus, Grafana) and observability frameworks; secure secrets and key management.
Job Skills & Experience
- 12+ years of software engineering experience.
- 4-6+ years of hands on smart contract development.
- Proven experience in regulated environments (banks, FMIs, exchanges, fintechs).
Core Technical Skills
- Advanced Solidity development.
- Experience with Ethereum, Hyperledger Besu and Corda.
- Token standards: ERC 20, ERC 721, ERC 1155 and hybrid models.
Financial Domain Knowledge
- Securities lifecycle management.
- Clearing and settlement processes.
- Corporate actions and custody.
- Delivery vs Payment (DvP) mechanisms.
System Integration
- Core banking integration.
- Payment systems and rails.
- Regulatory reporting platforms.
Hybrid On chain/Off chain Architectures
Experience designing hybrid on chain/off chain architectures that integrate seamlessly with existing financial systems.
