About Moca Network
Moca Network, one of Animoca Brands' flagship projects, is building the chain-agnostic digital identity infrastructure for the open internet by providing one universal account for a user's assets, identity, and reputation across multiple ecosystems. The primary product built by Moca Network is AIR Kit, a digital identity infrastructure that enables Web2 and Web3 projects to create a universal embedded account for users to own and use digital assets, identity, and reputation data, while gaining access to a suite of DeFi and consumer services provided by Moca Network's partners. AIR Kit empowers large user base apps to create their own app ecosystem natively with embedded blockchain features, while ensuring these users can use the same account, identity, reputation across all consumer apps on any chains that have adopted AIR Kit.
This Junior Smart Contract Developer would help design, implement, and maintain production-grade smart contracts powering Moca Network’s core products: onchain identity, asset primitives (ERC-721/1155/20), loyalty/rewards, and cross-project integrations. You’ll work closely with senior engineers and product teams to deliver secure, gas-optimised, and well-tested contracts that scale.
This is a hands-on role ideal for someone with 2–3 years of experience writing Solidity smart contracts and a strong understanding of EVM fundamentals, testing, and deployment practices.
Responsibilities
Implement and maintain Solidity smart contracts for tokens, access control, staking/rewards, allowlists, vesting, and upgradeable modules.
Write comprehensive Foundry/Hardhat tests (unit, fuzz, property-based, invariant) to ensure security and correctness.
Optimize gas usage, storage layout, and execution paths; profile and benchmark contract performance.
Integrate contracts with off-chain services and dApps via well-structured ABIs and event design; collaborate with frontend/backend teams.
Participate in code reviews, threat modeling, and audit cycles; respond to audit findings and contribute remediations.
Contribute to deployment pipelines, versioning, and multi-network release management (testnets and mainnets).
Create clear technical documentation for contracts, protocols, and integration guides.
Track ecosystem upgrades (EIPs, L2 features, account abstraction, ERC-4337, EigenLayer/LRT trends, etc.) and propose practical adoption paths.
Requirements
2–3 years of professional experience developing EVM smart contracts in Solidity.
Proficiency with Hardhat and/or Foundry for compilation, testing, and deployment.
Strong understanding of EVM execution model, opcodes, calldata/memory/storage, reentrancy, and delegatecall patterns.
Common standards: ERC-20, ERC-721, ERC-1155, EIP-2612, EIP-712, Ownable/AccessControl, Upgradeability (UUPS/Transparent).
Security best practices: access control, rate limiting, pull over push payments, checks-effects-interactions, pause/guardian patterns.
Familiarity with gas optimization techniques and tradeoffs.
Experience deploying to public testnets/mainnets and managing contract addresses, verifications, and ABIs.
Comfortable with Git, code reviews, and collaborative workflows.
