[Hiring] Blockchain Engineer @BITFIT LABS PTE LTD

Role Description

We are looking for a brilliant Blockchain Engineer to spearhead the core development of our decentralized offerings. In this role, you will architect and write secure smart contracts, integrate blockchain protocols into our client solutions, and ensure the flawless execution of Web3 business logic.

• Smart Contract Development: Design, develop, and deploy production-grade, highly secure smart contracts (using Solidity or Rust) for custom client needs.
• Protocol & dApp Integration: Build backend APIs and integrate Web3 libraries (ethers.js, web3.js, or Anchor) to connect front-end interfaces with blockchain protocols.
• Security Auditing & Testing: Write extensive unit tests, conduct internal security reviews, and optimize smart contracts to minimize gas fees and vulnerabilities (e.g., reentrancy, front-running).
• Tokenomics & DeFi Mechanics: Implement diverse token standards (ERC-20, ERC-721, ERC-1155, SPL) and custom logic for staking, DEXs, and automated market makers (AMMs).

Qualifications

• 3+ years of hands-on experience in Web3/Blockchain development with a solid portfolio of deployed contracts on Mainnet or Testnet.
• Strong command of Solidity (EVM) and/or Rust (Solana/Cosmos), along with modern development frameworks (Hardhat, Foundry, or Anchor).
• Thorough understanding of cryptography (public/private keys, hashing, zero-knowledge proofs), consensus mechanisms, and DeFi architectures.
• Eagerness to research and adopt emerging blockchain protocols to meet the unique requirements of our global client base.
