Distributed Ledger Technology (DLT) SME

Project description

Our client is advancing regulated, enterprise-grade distributed ledger solutions to support digital asset use‑cases, including custody, tokenization (fungible, non‑fungible, and hybrid), and stablecoin integrations across bank-grade environments. The program spans public and private DLT (e.g., Ethereum, Hyperledger Besu, Corda), enterprise security and privacy controls, and cloud‑native delivery (Azure/AWS/GCP). The DLT SME will help shape architecture, standards, and delivery of smart contracts, custody patterns (MPC/HSM, wallet policy engines), and observability within a highly regulated context.

Responsibilities

• Architecture & Design: Define DLT solution architectures across public/private chains (Ethereum, Hyperledger Besu, Corda) and align them with regulatory and enterprise standards. Model custody architectures using MPC/HSM, wallet policy engines, and secure enclave patterns. Smart Contract Engineering: Lead Solidity development, reviews, secure coding practices, and on-chain/off-chain integration patterns. Establish CI/CD for smart contracts, including test nets, audits, and controlled releases. Tokenization & Integrations: Design token models (fungible/NFT/hybrid), lifecycle management, and stablecoin integration patterns. Define interoperability, bridging, and oracle strategies with appropriate risk controls. Security & Privacy: Implement security fundamentals: key management, hardware enclaves/HSM, and secure enclave usage. Apply data‑privacy techniques (selective disclosure, ZK concepts) to meet compliance objectives. Cloud‑Native Delivery: Drive cloud-native implementation on Azure/AWS/GCP with Kubernetes, containers, Terraform, and secrets management. Set up observability stacks (Prometheus/Grafana) and operational SLIs/SLOs for DLT components. Governance & Standards: Define standards, reference implementations, and best practices for DLT platforms in regulated environments. Partner with Risk, Security, Compliance, and Audit to embed controls and evidence paths. Stakeholder Engagement: Collaborate with Solution Architects, PMs, and business owners; present designs and trade-offs to senior leadership. Support vendor selection, due diligence, and technical evaluations.

SKILLS

Must have

• 15+ years in software/technology roles with 4-6+ years building blockchain solutions in regulated contexts (banks, FMIs, fintech). Proven expertise across Public/Private DLT (Ethereum, Hyperledger Besu, Corda) and related standards. Solidity proficiency with demonstrable smart‑contract build and delivery. Hands-on knowledge of custody architectures: MPC/HSM, wallet policy engines. Experience in asset tokenization and stablecoin integrations. Strong cloud-native engineering: Azure/AWS/GCP, containers/Kubernetes, Terraform, CI/CD, secrets management, observability (Prometheus/Grafana). Solid grasp of security fundamentals (key mgmt.., enclave/HSM concepts, secure enclaves) and data privacy patterns (selective disclosure, ZK concepts).
