Blockchain Full Stack Developer

We’re looking for a Blockchain Full Stack Developer who can bridge blockchain innovation with full-stack engineering excellence. In this role, you’ll design, build, and scale decentralized applications (dApps) and blockchain-integrated platforms that power secure, transparent, and efficient digital ecosystems. You’ll collaborate with product managers, blockchain architects, and DevOps engineers to deliver high-impact solutions that leverage distributed ledger technology, smart contracts, and scalable web architectures.

This position is ideal for someone who thrives at the intersection of blockchain protocols, cloud infrastructure, and full-stack development, and wants to shape how next-generation applications are designed and deployed.

Design, develop, and deploy smart contracts on Ethereum or similar blockchain networks.

Integrate blockchain APIs and crypto payment systems into existing and new web applications.

Contribute to consensus mechanism design, token standards (ERC20, ERC721, etc.), and blockchain interoperability.

Ensure security-first architecture, including wallet integration, key management, and encryption best practices.

Build and maintain scalable front-end interfaces using React.js, Next.js, or Vue.js.

Develop robust backend systems and APIs using Node.js and TypeScript.

Create and manage real-time data pipelines and RESTful services that connect blockchain layers with user applications.

Implement microservice architectures and optimize system performance for scalability and low latency.

Use Docker, Kubernetes, and CI/CD pipelines to automate builds, testing, and deployments.

Manage application hosting and scalability across cloud environments (AWS, GCP, Azure).

Implement monitoring, version control (GitHub, GitLab), and secure deployment best practices.

Partner with product and design teams to translate user needs into functional blockchain-powered features.

Participate in architecture reviews, sprint planning, and technical documentation.

Build Proof of Concepts (POCs) and Minimum Viable Products (MVPs) to validate blockchain use cases.

Support post-deployment monitoring, optimization, and maintenance of production systems.

3–7 years of experience in full-stack software development, including at least 2 years in blockchain-based projects.

Strong proficiency in TypeScript, Node.js, and React.js or similar front-end frameworks.

Proven expertise in smart contract development using Solidity or equivalent.

Familiarity with Ethereum, Bitcoin, Polygon, or similar blockchain networks.

Experience with crypto payment integrations, Web3.js, or Ethers.js.

Knowledge of DevOps tools (Docker, Kubernetes, Jenkins, GitLab CI/CD).

Solid understanding of distributed systems, consensus mechanisms, and cryptography.

Strong problem-solving, debugging, and analytical skills.

Excellent collaboration and communication abilities in agile, cross-functional teams.

Bachelor’s or Master’s degree in Computer Science, Information Technology, or a related field.

Contributions to open-source blockchain or Web3 projects.

Experience deploying dApps on Ethereum or Layer-2 solutions.

Understanding of zero-knowledge proofs, DeFi protocols, or NFT platforms.

Familiarity with HSM-based key management and blockchain security audits.
