Smart Contract Developer (Solidity / Rust)

About the Role

Smart Contract Developer

Youll work alongside engineers, auditors, and product leads to build secure, scalable, and innovative blockchain-based products.

Key Responsibilities

• Design and implement smart contracts using

  Solidity

  (for EVM-based chains) or

  Rust

  (for Solana or other Rust-based chains).
• Develop secure, gas-efficient, and well-documented smart contracts.
  
• Collaborate with product managers and designers to translate business logic into smart contracts.
  
• Write unit and integration tests to ensure contract reliability.
  
• Conduct code reviews and participate in security audits (internal or external).
  
• Stay up to date with the latest industry trends, tooling, and best practices in blockchain development.
  
• Work with frontend/backend teams to integrate smart contracts into full-stack dApps.
  
• Optimize contracts for performance and scalability.

Required Skills & Qualifications

• Strong experience with

  Solidity

  (EVM chains like Ethereum, Polygon, Avalanche) and/or

  Rust

  (Solana, Near, etc.).
• Deep understanding of Ethereum and/or Solana architecture and smart contract lifecycles.
  
• Familiarity with token standards:

  ERC-20

  ,

  ERC-721

  ,

  ERC-1155

  ,

  SPL tokens

  .
• Hands-on experience with tools like

  Hardhat

  ,

  Foundry

  ,

  Truffle

  ,

  Remix

  , or

  Anchor

  (for Solana).
• Strong grasp of blockchain fundamentals: gas, transactions, nodes, consensus, etc.
  
• Experience with unit testing smart contracts using

  Chai

  ,

  Mocha

  ,

  Waffle

  , or similar.
• Version control using

  Git

  and collaborative coding (GitHub, GitLab).
• Understanding of common smart contract vulnerabilities (e.g., reentrancy, integer overflow) and how to prevent them.

Nice to Have (Bonus Skills)

• Experience working with

  Chainlink

  ,

  The Graph

  , or other web3 integrations.
• Prior experience with

  zero-knowledge proofs

  ,

  zk-Rollups

  , or privacy-preserving contracts.
• Experience with DeFi, NFT, or DAO-based projects.
  
• Familiarity with wallet integrations (e.g., MetaMask, Phantom).
  
• Contributions to open-source blockchain projects.
  
• Understanding of L2s and bridges (Optimism, Arbitrum, zkSync).
