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.

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.

Strong problem-solving skills and ability to write clean, maintainable code.

Preferred Skills

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.

Level of studies: Bachelor’s degree in Computer Science, Software Engineering, Mathematics, or a related technical field.
(A Master’s degree or equivalent experience in blockchain development is a plus.)

Language Requirements: Fluent in English
