How our sorting works

The order in which job vacancies are displayed is determined by a composite score based on the following factors:

  • Keyword Relevance: How well your search terms match the vacancy details. We prioritize matches found in the job title, followed by job requirements, location names, and educational levels. Matches within general employer information or the organization's name carry a lower weight.
  • Commercial Prioritization (Premium Jobs): Vacancies paid for by employers ('Premium' or 'Sponsored') receive a ranking boost and will appear higher in the search results.
  • Recency (Date Relevance): Newer vacancies are prioritized. The relevance score of a vacancy is reduced by half once the posting is older than 30 days.
  • Proximity (Distance Relevance): Vacancies located closer to your search location are ranked higher. For vacancies located more than 30 km from the search center, the relevance score is halved.
The final ranking is established by multiplying all these individual factors to calculate the total relevance score.

    Location: UK / Fully Remote (Occasional pre-agreed travel)
    Duration: 8 Months
    Rate: Negotiable

    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.

    How to Apply

    If you are a hands-on architect looking to deliver a high-impact project within the digital asset/blockchain space, please submit your updated CV and availability to schedule a call.
