About the Role

We are seeking a highly skilled, hands-on Blockchain Architect to lead the end-to-end design, development, and delivery of enterprise-grade distributed ledger solutions. This role combines technical leadership with active coding, taking solutions from initial Proof of Concept (PoC) straight through to production. You will collaborate closely with cross-functional data, cloud, and DevOps teams to deliver secure, scalable, and highly compliant systems.

Key Responsibilities

  • Architectural Leadership: Lead end-to-end design of blockchain solutions, including consensus models, data structures, cryptographic frameworks, and node architectures.
  • Platform Evaluation: Select and implement optimal blockchain platforms (e.g., Ethereum, Hyperledger Fabric, Corda, Polygon, Avalanche) based on enterprise needs.
  • Hands-on Engineering: Actively contribute to the development of smart contracts and core components.
  • Integration & Scaling: Define API layers, node data flows, and enterprise integration patterns for legacy systems.
  • Security & Governance: Implement strict security best practices (key management, node communication) and define data privacy and access models (GDPR, KYC/AML compliance).

Skills & Experience Required

  • Overall Experience: 8+ years of experience within software engineering and enterprise architecture.
  • Blockchain Expertise: 3+ years of dedicated, hands-on experience designing and delivering distributed ledger systems.
  • Platforms & Smart Contracts: Deep technical proficiency with Ethereum, Hyperledger, or Corda, alongside smart contract development languages (Solidity, Chaincode, DAML, or Rust).
  • Core Development: Strong background in languages like Java, Python, Go, or Rust.
  • Cloud & DevOps: Solid understanding of modern cloud platforms (AWS, Azure, or GCP) and automated CI/CD deployment pipelines.
  • Industry Frameworks: Prior experience working within heavily regulated environments (FinTech, Banking, or Enterprise) with an understanding of cryptography and data sovereignty.
