WebBlockchain Developer

We are seeking a passionate and experiencedWeb3 Blockchain Developerto join our team in building secure, scalable, and user-friendly decentralized applications and protocols. You will be responsible for developing smart contracts (coded and no-code), blockchain infrastructure, Layer 1/Layer 2 systems, and integrating decentralized technologies with real-world workflows.

This role is ideal for amid-to-senior level engineerexcited about decentralization, open-source ecosystems, and next-generation internet infrastructure. You’ll work cross-functionally with product, frontend, Dev Ops, compliance, and UX teams to bring Web3 products to life—securely, efficiently, and at scale.

Work requirements and tasks will be guided by the department’s Standard Operating Procedures (SOP) Manual

which is reviewed periodically, but will fall broadly in the following Key Responsibility Areas (KRAs):

• Design, develop, and maintain Layer‑1 and Layer‑2 blockchain modules with high throughput and instant finality.
• Build coded and no-code smart contract systems (e.g., Auto Tasks, low-code platforms), including ISO
  20022–compliant financial bridges.
• Develop and deploy smart contracts using Solidity, Rust, or similar; optimize for gas efficiency and upgradeability.
• Contribute to UX‑friendly Super App APIs (e.g., wallet integration, transaction UX, SSO support).
• Integrate with popular Web3 wallets (e.g., Meta Mask, Wallet Connect), decentralized identity (DID) systems, and on/off-chain data flows.
• Implement secure key management practices using HSMs, TLS, and encrypted storage; manage node infrastructure and P2P networking.
• Write thorough unit/integration tests, assist in audits, and maintain smart contract security best practices.
• Collaborate with product, Dev Ops, and compliance teams to align blockchain functionality with business workflows and regulations.
• Stay up-to-date with emerging blockchain trends, including Layer 2 solutions (zk Rollups, optimistic rollups), DAO tooling, cross-chain bridges, and privacy enhancements.
• Utilize infrastructure tools like Alchemy, Infura, and indexing platforms such as The Graph; manage RPC endpoints and explore new tooling to enhance performance.

• Bachelor’s degree in computer science, Engineering, Information Systems, or a related field.

• 3+ years in blockchain or smart contract development.
• Strong command of:
• Smart contract languages:
  Solidity, Rust, or similar.
• Node operations and peer-to-peer networking fundamentals.
• Deep understanding of:
• Security best practices for smart contracts and infrastructure.
• Financial messaging standards (e.g., ISO
  20022) is a strong plus.
• Experience integrating blockchain with:
• Web frontends (React/Next.js, Vue, etc.)
• Mobile-first UX and single sign-on (SSO) implementations.

• Familiarity with Super App design and multi-service dApp ecosystems.
• Experience with no-code smart contract platforms (e.g., Thirdweb, Moralis).
• Prior work in government or enterprise blockchain integrations.
• Contributions to open source blockchain projects or DAO governance tools.
• Experience in DeFi, tokenomics, or cross-chain bridges.
• Knowledge of decentralized identity (DID), zk-SNARKs, or verifiable credentials.

Hands-on experience with HSMs, TLS, and secure enclave storage systems.
