We are looking for a highly experienced Blockchain Developer with over 12 years of industry expertise to design, build, and maintain secure, scalable blockchain platforms and decentralized applications. This is a contract role for someone who deeply understands blockchain architecture, smart contracts, cryptography, and distributed systems. You will work closely with engineering, product, and security teams to build reliable blockchain solutions that support business and technology goals.
Key Responsibilities
- Design and develop blockchain-based solutions, including smart contracts, consensus algorithms, and decentralized applications.
- Build and maintain secure and scalable blockchain infrastructure and APIs.
- Evaluate emerging blockchain technologies and recommend integration approaches.
- Optimize existing blockchain architecture for performance, cost, and reliability.
- Develop smart contracts using platforms such as Ethereum, Hyperledger, or other relevant chains.
- Implement cryptographic and security best practices to protect digital assets.
- Integrate blockchain solutions with front-end and back-end systems.
- Diagnose issues, perform debugging, and participate in code reviews.
- Collaborate with cross-functional teams including DevOps, Cloud, Security, and Product.
- Produce clear documentation, architecture designs, and technical specifications.
- 12+ years of hands-on software development experience, with a strong focus on blockchain.
- Strong background in smart contract development using Solidity, Rust, Go, or similar languages.
- Deep understanding of blockchain protocols, nodes, distributed ledgers, tokens, and wallets.
- Experience with Ethereum, Hyperledger Fabric, Polygon, Corda, or similar blockchain frameworks.
- Proficiency with cryptography concepts, hashing algorithms, zero-knowledge proofs, and consensus mechanisms.
- Strong understanding of distributed systems, microservices, and cloud technologies.
- Experience integrating blockchain with web or mobile applications.

What is Truffle Blockchain?
Truffle is a popular development framework for building decentralized applications (dApps) on blockchain platforms, including Ethereum, Binance Smart Chain, and others
The framework provides developers with a suite of tools that make it easier to create, test, and deploy smart contracts and dApps
Truffle also includes a number of integrations with other blockchain development tools and platforms, such as Ganache for local blockchain development and Metamask for Ethereum wallet management
Truffle includes a number of features that simplify the development process, such as:
- Smart contract compilation and migration: Truffle automatically compiles and deploys smart contracts to the blockchain network, making it easier for developers to manage the deployment process.
- Testing framework: Truffle includes a built-in testing framework that enables developers to test their smart contracts and dApps with a variety of testing tools and approaches.
- Debugging and logging: Truffle provides tools for debugging and logging smart contract code, making it easier to diagnose and fix errors and issues during development.
- Built-in libraries: Truffle includes a number of built-in libraries that provide common smart contract functionality, such as OpenZeppelin for token standards and SafeMath for secure arithmetic operations.
