As a key member of our team, you will work on building and maintaining blockchain applications, developing smart contracts, and implementing solutions using decentralized technologies.


You will play a crucial role in creating blockchain-powered products, integrating cryptocurrency protocols, and contributing to the evolution of decentralized finance (DeFi) and related blockchain technologies.


Key Responsibilities:



  2. Blockchain Development:

  • Design and develop decentralized applications (dApps) using blockchain technologies such as Ethereum, Binance Smart Chain, Solana, Polkadot, and others.
  • Implement and deploy smart contracts on blockchain platforms, ensuring their functionality, security, and scalability.
  • Develop and integrate crypto wallets, token standards (ERC-20, ERC-721, etc.), and custom blockchain protocols into applications.


Smart Contract Development:

  • Write, test, and deploy secure and efficient smart contracts using languages like Solidity, Rust, or Vyper.
  • Conduct security audits and reviews of smart contracts to ensure they are resistant to vulnerabilities like reentrancy attacks, overflow/underflow, etc.
  • Collaborate with other developers to ensure seamless integration of smart contracts with frontend and backend systems.


Cryptocurrency Protocols & Wallet Development:

Blockchain Infrastructure & Integration:

  • Build and maintain the backend infrastructure to support blockchain applications, including nodes, APIs, and services.
  • Ensure smooth integration of blockchain systems with traditional applications and web technologies (e.g., REST APIs, web3.js, ethers.js).


Blockchain Solutions for DeFi & NFTs:

  • Develop decentralized finance (DeFi) protocols, including decentralized exchanges (DEXs), liquidity pools, staking mechanisms, and yield farming.
  • Build and integrate NFT platforms, minting smart contracts, and marketplaces using ERC-721 and ERC-1155 token standards.


Performance Optimization & Scalability:

  • Optimize blockchain code for speed, performance, and scalability, ensuring that dApps and smart contracts can handle high transaction volumes.
  • Monitor blockchain performance and resolve bottlenecks or latency issues.


Security & Audits:

  • Follow best practices for blockchain security and conduct regular audits to identify potential vulnerabilities.
  • Work with internal security teams or third-party auditors to ensure code quality, integrity, and safety.


Research & Innovation:

  • Stay updated with the latest developments in blockchain technology, cryptocurrency protocols, and decentralized technologies.
  • Contribute to research and development of new blockchain features, tokens, and smart contract innovations.


Required Qualifications:



  • At least 4 years of experience in blockchain development, cryptocurrency development, or smart contract development.
  • Degree in Computer Science, Software Engineering, Blockchain Development, or a related field is preferred.


Benefits:



  • Competitive salary based on experience.
  • Health insurance and other company benefits.
  • Opportunities for professional development, certifications, and attending blockchain-related conferences and events.
  • Flexible working hours and a collaborative work environment.
  • The chance to work on exciting, cutting-edge blockchain projects that could shape the future of cryptocurrency.
