Animoca Brands realizes its mission via three integrated business pillars: operating Web3 businesses to advance blockchain adoption with native projects such as Moca Network, Anichess, The Sandbox, Open Campus, NEOM Web3 initiatives, and a regulated stablecoin project in partnership with Standard Chartered and HKT; providing digital asset advisory services including tokenomics advisory, liquidity provisioning, and institutional research to help external Web3 projects grow; and investment management, with a portfolio of investments in over 540 companies including industry leaders Pudgy Penguins, Yuga Labs, Axie Infinity, Polygon, Consensys, Magic Eden, OpenSea, Dapper Labs, YGG, and many others.
We are looking for a highly skilled Full Stack Engineer to join our mission of building a decentralized future. You will be at the forefront of creating seamless, secure, and innovative applications that bridge the gap between traditional web experiences and the blockchain.
As a Full Stack Engineer, you will be responsible for the end-to-end development of decentralized applications (dApps) within the Animoca Brands ecosystem. You will work across the entire stack—from crafting responsive user interfaces to architecting robust backend services—all while ensuring deep integration with the EVM ecosystem.
Responsibilities
- Web3 Integration: Design and build scalable frontend interfaces that interact seamlessly with the blockchain using libraries like Ethers.js, Viem, or Web3.js.
- Backend Architecture: Develop and maintain high-performance APIs and microservices (Node.js/TypeScript) to support our growing ecosystem of games and platforms.
- Security First: Implement and maintain rigorous security standards across the full stack to protect against common Web3 vulnerabilities (e.g., front-running, reentrancy awareness, and secure private key management).
- EVM Implementation: Work deeply within the EVM ecosystem, managing transaction lifecycles, gas optimizations, and interaction with various Layer 2 solutions.
- Collaboration: Work closely with product managers, UI/UX designers, and smart contract engineers to translate complex blockchain concepts into user-friendly products.
Qualifications
- Blockchain Fundamentals: Deep understanding of how the EVM works. You should be comfortable with providers, signers, transaction broadcasting, and indexing blockchain data.
- Full-Stack Security: Proven experience in securing Web3 applications. This includes knowledge of OWASP Top 10 for the web and specific security patterns for decentralized interfaces.
- Modern Frontend: Proficiency in React.js (or Next.js) and TypeScript, with a focus on building performant, state-driven applications.
- Robust Backend: Strong experience in Node.js and relational databases (PostgreSQL) or NoSQL solutions.
Preferred qualifications
- Smart Contract Development: Hands-on experience writing, testing, and deploying Solidity contracts using Hardhat or Foundry is a significant advantage.
- DeFi/NFT Knowledge: Familiarity with ERC-20, ERC-721, and ERC-1155 standards.
- Infrastructure: Experience with Docker, Kubernetes, or AWS cloud services.
The Perks of Joining Animoca Brands:
A Vibrant and Diverse Workplace: Immerse yourself in a dynamic, multi-cultural environment with colleagues from over 15 nationalities (and growing!). We celebrate diversity and foster a global perspective.
Incentives in the Web3 Space: Be a part of the future and align your success with the growth of our innovative projects.
Direct Impact and Flat Structure: Your voice matters. We operate with a flat organizational structure, ensuring your ideas are heard and implemented quickly.
Comfortable and Creative Atmosphere: Embrace a relaxed and productive work environment with casual attire.
Opportunities Across the Ecosystem: Expand your horizons by collaborating with various subsidiary brands within the Animoca Brands network, gaining exposure to a wide range of projects and technologies.
Comprehensive Benefits Package: We care about your well-being. Enjoy a comprehensive benefits package, including medical, life, and transportation allowances.

What is ERC20 example?
ERC20 is a standard for fungible tokens on the Ethereum blockchain
Here is an example of an ERC20 token
Let's say we create a new ERC20 token called ABC Token with a total supply of 1,000,000 tokens
Each token will be divisible up to 18 decimal places
To implement the ERC20 standard, we will need to define several functions, including:
- balanceOf(address): Returns the token balance of a specific address.
- transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
- approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
- allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
- User1 owns 500,000 ABC Tokens.
- User2 wants to buy 100 ABC Tokens from User1.
- User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
- User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
- The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
