Role Overview
We are seeking a highly skilled and security-conscious Blockchain Developer with deep expertise in Solidity, EVM-compatible chains, and smart contract architecture. You will play a critical role in building the token issuance and lifecycle management layer, integrating with custodians, KYC providers, and internal APIs.

Key Responsibilities
- Design, develop, and deploy secure smart contracts (Solidity) for tokenized assets (bonds, real estate, funds).
- Integrate smart contracts with backend services and the broader platform (NestJS, PostgreSQL).
- Collaborate with legal and compliance teams to implement regulatory-compliant token standards.
- Conduct peer reviews, write tests, and perform audits to ensure robust contract security.
- Interface with blockchain infrastructure (e.g., Polygon Edge, Hyperledger Besu) and custody APIs.
- Support sandbox simulations and testnet deployments for regulatory pilots.

Required Qualifications
- 3+ years in blockchain development with hands-on Solidity experience.
- Deep knowledge of EVM-compatible chains, token standards (ERC-20, ERC-1400, ERC-3643), and smart contract patterns.
- Experience with private chain deployments (Polygon Edge, Hyperledger Besu preferred).
- Familiarity with backend integration (GraphQL APIs, Node.js/NestJS).
- Understanding of tokenization legal wrappers, compliance, and asset lifecycle management is a plus.
- Strong understanding of security best practices in smart contract development.
