Matrixdock is a real-world asset (RWA) tokenization platform, offering tokenized gold (XAUm), tokenized silver (XAGm), and a short-term treasury bill token (STBT). XAUm is fully backed 1:1 by LBMA-accredited gold bars of 99.99% purity and is live on Ethereum, BSC, Solana, Sui, and other major chains. You will join the core smart contract team and own the on-chain systems that carry real assets.

• Design, build, and ship the core smart contracts for our tokenized RWA products
• Build and maintain protocol implementations across EVM chains (Ethereum / BSC / Tron) and non-EVM chains (Solana / Sui / Stellar), adapting the design to each chain’s native model, and enable multi-chain issuance and cross-chain transfers through messaging protocols such as Layer Zero and CCIP
• Build the contract security and governance framework — access control, timelocked operations, and upgradeable architecture (UUPS proxy) — ensuring safe, controlled upgrades and backward-compatible storage layouts
• Develop a deep understanding of leading DeFi protocols (e.g., Uniswap, Aave) and own third-party protocol integrations
• Write secure, gas-efficient contract code with high test coverage; drive third‑party security audits and remediate findings
• Build on‑chain monitoring and operations tooling to detect anomalous events, especially around fund‑sensitive operations such as minting and burning
• Stay current with EIPs, new chain features, and industry security incidents; evaluate and integrate relevant advances into our stack
• Contribute to the overall architecture of our blockchain systems and provide technical guidance to team members
• Bachelor’s degree or above in Computer Science or a related field; 5+ years of software development experience, including 2+ years in smart contract development
• Strong proficiency in at least one major blockchain platform such as Ethereum, Solana, or Sui, with hands‑on smart contract development in Solidity, Rust, or Move; deep understanding of your chain’s execution model, gas mechanics, and storage layout; practical experience with upgradeable contracts, including performing live upgrades
• Proficiency with the mainstream development frameworks for your chain (e.g., Hardhat / Foundry, Anchor, Sui CLI), with solid engineering practice across testing, fuzzing, deployment, and on‑chain…
