• Build scalable backend services that interact with blockchain networks for transaction processing, asset management, and identity verification.
• Develop RESTful and GraphQL APIs to expose blockchain functionality to web and mobile applications.
• Design blockchain data models, token standards, and transaction workflows for high-volume enterprise systems.
• Integrate enterprise applications with Ethereum, Hyperledger Fabric, Polygon, Avalanche, or other blockchain platforms.
• Develop secure wallet integrations, digital signature workflows, and key management solutions.
• Implement blockchain event listeners, indexing services, and off-chain processing components.
• Build scalable microservices using .NET Core, Java, or Node.js that interact with blockchain networks.
• Optimize smart contracts for gas efficiency, scalability, and transaction throughput.
• Perform smart contract audits, security testing, and vulnerability assessments before production deployments.
• Collaborate with DevOps teams to deploy blockchain infrastructure across Azure or AWS cloud environments.
• Participate in architectural reviews, code reviews, technical design sessions, and production support activities.
• Troubleshoot complex blockchain network issues, transaction failures, synchronization problems, and production incidents.

Qualifications

• Six or more years of professional software development experience building enterprise-grade distributed applications.
• Three or more years of hands-on blockchain development experience delivering production blockchain solutions.
• Strong experience developing smart contracts using Solidity and Ethereum Virtual Machine (EVM)-compatible networks.
• Hands-on experience with blockchain platforms such as Ethereum, Hyperledger Fabric, Polygon, Avalanche, Binance Smart Chain, or Quorum.
• Strong proficiency in JavaScript/TypeScript with Node.js or backend development using C#/.NET Core or Java.
• Experience building decentralized applications (dApps) with React, Angular, or Vue.js.
• Strong understanding of blockchain architecture, consensus algorithms, cryptographic hashing, digital signatures, Merkle trees, and distributed ledger concepts.
• Experience implementing ERC-20, ERC-721, ERC-1155, or custom token standards.
• Experience integrating wallets such as MetaMask, WalletConnect, Coinbase Wallet, or enterprise custody platforms.
• Strong experience with REST APIs, GraphQL APIs, WebSockets, and blockchain RPC interfaces.
• Experience working with SQL and NoSQL databases including PostgreSQL, SQL Server, MongoDB, or Redis.
• Hands-on experience with Git, CI/CD pipelines, automated deployments, and release management.
• Experience deploying applications on Azure or AWS cloud platforms.
• Strong debugging, performance optimization, and troubleshooting skills in production environments.
• Experience working within Agile Scrum development teams.

Requirements

• Experience designing enterprise blockchain solutions for financial services, healthcare, insurance, or supply chain industries.
• Hands-on experience with Hyperledger Fabric chaincode development using Go or Java.
• Experience with Layer-2 scaling solutions including Polygon, Arbitrum, or Optimism.
• Familiarity with Zero-Knowledge Proofs (ZKP), Multi-Party Computation (MPC), or privacy-preserving blockchain technologies.
• Experience implementing decentralized identity (DID) and Verifiable Credentials (VC).
• Knowledge of blockchain security standards, smart contract auditing tools, and common vulnerabilities such as reentrancy, overflow, front-running, and flash loan attacks.
• Experience using Hardhat, Foundry, Truffle, Ganache, Brownie, or Remix IDE.
• Familiarity with Docker, Kubernetes, Terraform, and Infrastructure as Code.
• Experience integrating blockchain applications with enterprise identity providers including Azure Active Directory or OAuth.
• Blockchain certifications or contributions to open-source blockchain projects are highly desirable.

Project Environment

You will be joining a team building a next-generation enterprise blockchain platform supporting:

• Digital asset tokenization and lifecycle management
• Smart contract-driven business workflows
• Enterprise wallet and digital identity integration
• Real-time blockchain event processing
• Secure multi-signature transaction approval systems
• Blockchain analytics and reporting dashboards
• Cloud-native microservices deployed on Azure and AWS
• High-availability distributed systems supporting millions of secure transactions annually

This is a hands-on engineering role where you'll contribute to architecture, development, deployment, security, and operational excellence across mission-critical blockchain solutions.
