Blockchain Developer

WisewayTec is seeking a Blockchain Developer to work directly with senior blockchain architects on global-scale Web3 projects across DeFi, NFTs, Layer-2s, DEXs, and enterprise blockchain ecosystems. You will bring hands-on expertise in EVM chain forking, smart contract development, and decentralized application architecture to build full-stack blockchain applications.

What you'll do

• Fork and customize EVM-based blockchains such as Ethereum, BNB Chain, Polygon, and Avalanche; set up and configure networks using PoS, PoA, and PoW consensus mechanisms.
• Create and modify genesis files, set up validators or miners, and configure core network parameters.
• Run and maintain private networks and devnets using Geth, Parity, or OpenEthereum.
• Manage RPC node setup, peer discovery, node syncing, and optimize chain performance and security.
• Design, develop, and deploy smart contracts using Solidity, Hardhat, and Truffle on EVM chains.
• Build and maintain DApps, DeFi protocols, NFT modules, and multi-token ecosystems.
• Implement token standards such as ERC-20, ERC-721, and ERC-1155, including upgradable and custom logic.
• Perform unit testing, basic auditing checks, and follow secure coding practices.
• Participate in code reviews and ensure adherence to best practices in Web3 development.
• Integrate blockchain functionality using Web3.js or Ethers.js.
• Collaborate with React, Next.js, and Node.js teams to build scalable Web3 applications.
• Work closely with UI/UX, QA, and project managers to ensure smooth feature delivery.
• Prepare documentation, track sprints, and support deployments across testnets and mainnets.
• Explore new frameworks, Layer-2 technologies, chain-bridging tools, and interoperability mechanisms.
• Stay updated on DeFi, DEX mechanisms such as v2 and v3 pools, and liquidity provisioning strategies.
• Contribute to internal R&D projects involving AI x Blockchain, modular chains, and ZK technologies.

What you bring

• A Bachelor's degree in Computer Science, IT, Engineering, or related discipline.
• 1 to 3 years of hands-on blockchain or full-stack development experience.
• Strong knowledge of Solidity, EVM architecture, Hardhat, and Truffle.
• Experience with JavaScript or TypeScript, Node.js, and React or Next.js.
• Understanding of cryptography fundamentals, wallet architecture, and token standards.
• Practical exposure to DEX v2/v3, liquidity provisioning, and AMM concepts.
• Familiarity with Git, version control, and Agile or Scrum workflows.

Nice to have

• Experience with DeFi protocols, NFT minting engines, or blockchain explorer APIs.
• Database knowledge in MongoDB or PostgreSQL.
• Awareness of Layer-2s, rollups, bridges, and cross-chain messaging frameworks.
• Experience with Cosmos SDK or Tendermint-based chains.
• Interest in AI and Blockchain integration.

What we offer

• Work directly with senior blockchain architects on global-scale Web3 deployments.
• Training, mentorship, and opportunities to work on advanced blockchain R&D.
• Flexible work culture with high-growth potential.
• Competitive salary plus performance bonuses.
• Opportunity to contribute to core blockchain infrastructure and custom chain deployments.
