Role description
Key Responsibilities
Product Development
Architect, design, and develop core modules of the Blockchain Data Management platform (data governance, lineage tracking, and MDM).
Implement smart contracts and consensus mechanisms to ensure transparency, immutability, and trust across the platform.
Build APIs and integration services to connect blockchain layers with existing fintech systems.
Blockchain Engineering
Design and optimize decentralized ledger structures to store governance metadata, lineage logs, and master data references.
Ensure scalability, security, and fault tolerance of the blockchain network.
Evaluate blockchain frameworks (e.g., Hyperledger Fabric, Ethereum, Quorum, Polygon) and recommend the best fit for fintech data use cases.
Data Management
Develop mechanisms to capture and track data lineage across multiple data sources.
Build frameworks for Master Data Management using blockchain identity and tokenization principles.
Implement rule-based data governance policies aligned with fintech regulations.
Required Skills & Experience
Core Technical Skills
10 years of experience in software engineering with at least 2–3 years in Blockchain development.
Proficiency in blockchain frameworks: Hyperledger Fabric, Ethereum (Solidity), Quorum, or similar.
Strong programming expertise in Python, Go, Java, or Node.js.
Hands-on experience with smart contract development and DApps.
Knowledge of distributed systems, consensus algorithms, and cryptographic principles.
Data Engineering & Governance
Familiarity with data lineage, data cataloging, and metadata management tools.
Experience with Master Data Management (MDM) solutions and principles.
Understanding of data governance frameworks and fintech compliance (e.g., GDPR, CCPA, PCI DSS).
Architecture & Tools
Experience with microservices, containerization (Docker, Kubernetes), and cloud platforms (AWS, Azure, GCP).
Strong knowledge of RESTful APIs, GraphQL, and event-driven architectures (Kafka, RabbitMQ).
Proficiency with CI/CD pipelines, Git, and DevOps practices.
Nice-to-Have
Experience with fintech platforms and regulatory data compliance.
Exposure to Zero-Knowledge Proofs, Decentralized Identity (DID), or Tokenization for sensitive data.
Knowledge of AI/ML integration for anomaly detection in data lineage or governance.
