About the Role :
We are looking for a senior Web3 developer to design and build scalable, secure backend systems that power blockchain-based financial products.

- Apply strong proficiency in TypeScript to build robust, type-safe applications and integrations across the Web3 stack.
- Work hands-on with Web3 libraries such as ethers.js, web3.js, or equivalent tooling to interact with EVM-based chains, including smart contract calls, transaction management, and event listening.
- Demonstrate a deep understanding of tokenization standards (ERC-20, ERC-721, ERC-1155, ERC-3643), and apply this knowledge to build or integrate token issuance, transfer, and compliance mechanisms.
- Contribute to digital asset trading systems, including order matching engines, real-time market data feeds, and integration with exchange APIs for trade execution and settlement.
- Bring prior experience working with institutional-grade digital asset platforms - such as exchanges, custodians, or tokenization providers - with an understanding of the security, compliance, and operational rigor these environments demand.
