We are looking for a highly skilled Blockchain Developer with expertise in Solidity and Rust to join our growing engineering team. You will play a key role in developing and optimizing smart contracts, blockchain protocols, and DeFi components that power the Caiz ecosystem.

As part of the core blockchain development team, you’ll work on both Ethereum-compatible smart contracts and Rust-based custom chain logic, contributing to secure, scalable, and innovative blockchain infrastructure.

Responsibilities:

• Design, develop, and deploy smart contracts using Solidity on EVM-compatible blockchains.
• Build and maintain Rust-based blockchain modules, such as on Substrate or Solana-compatible platforms.
• Contribute to the design of custom blockchain protocols and token standards.
• Write secure, gas-optimized, and thoroughly tested smart contracts.
• Collaborate with frontend and backend teams to integrate blockchain components into products.
• Conduct code reviews, audits, and vulnerability assessments for blockchain code.
• Analyze and improve the performance, security, and scalability of the Caiz blockchain.
• Stay up-to-date with the latest developments in blockchain technologies, including new EIPs, cryptographic primitives, and layer-2 solutions.

Qualifications

• 3+ years of experience in blockchain development with hands-on coding in Solidity and Rust.
• Strong understanding of smart contract design, blockchain architecture, cryptography, and consensus mechanisms.
• Experience developing and deploying smart contracts on Ethereum or similar EVM chains.
• Proficiency in Rust for blockchain environments such as Substrate or Solana.
• Familiarity with Web3.js, Ethers.js, Hardhat, Truffle, and related tools.
• Understanding of DeFi protocols, token standards (ERC-20, ERC-721, etc.), and layer-1/layer-2 ecosystems.
• Experience with version control systems (Git) and CI/CD workflows.
• Strong problem-solving skills and ability to write clean, maintainable code.

Requirements

• Experience in building or contributing to a Layer 1 or Layer 2 blockchain.
• Knowledge of blockchain security best practices and audit processes.
• Exposure to zero-knowledge proofs (ZK), rollups, or cross-chain bridges.
• Experience in working within agile or startup environments.
• Understanding of Islamic finance or Sharia-compliant financial principles is a plus.

Benefits

• Competitive Financial Compensation: We offer financial benefits that reflect the value of your work and dedication.
• Work Flexibility: Enjoy the flexibility to work from home, the office, or even abroad.
• Annual Holidays: Generous paid time off to help you maintain a healthy work-life balance.
