Web3 Developer
POSITION OVERVIEW
- We are seeking a passionate and experienced Web3 Blockchain Developer to 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 a mid-to-senior level engineer excited about decentralization, open-source ecosystems, and next-generation internet infrastructure. You’ll work cross-functionally with product, frontend, DevOps, compliance, and UX teams to bring Web3 products to life—securely, efficiently, and at scale.
ROLE AND RESPONSIBILITIES
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):
Technical 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., AutoTasks, 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 SuperApp APIs (e.g., wallet integration, transaction UX, SSO support).
- Integrate with popular Web3 wallets (e.g., MetaMask, WalletConnect), 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, DevOps, and compliance teams to align blockchain functionality with business workflows and regulations.
- Stay up-to-date with emerging blockchain trends, including Layer 2 solutions (zkRollups, 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.
Requirements
PERSON SPECIFICATIONS
Academic Qualifications
- Bachelor’s degree in computer science, Engineering, Information Systems, or a related field.
Experience
- 3+ years in blockchain or smart contract development.
- Strong command of:
- Smart contract languages: Solidity, Rust, or similar.
- General-purpose languages: TypeScript/JavaScript, Python, or Go.
