Blockchain Engineering Intern (Ethereum / Web3 Infrastructure)
Company: World Trade Factory (SKXYWTF)
Location: Remote / Hybrid
Type: This is an Unpaid Internship starting immediately
About the Role
World Trade Factory is building next-generation digital infrastructure at the intersection of blockchain, AI, and global markets. We are looking for a Blockchain Engineer to help design, build, and test smart-contract-based systems and supporting infrastructure in an educational, research-driven, and production-oriented environment.
This role focuses on engineering, security, and architecture — not hype or speculation.
What You’ll Work On
Design and develop smart contracts on Ethereum and EVM-compatible chains
Implement and test ERC standards (ERC-20, ERC-721, ERC-1155 as needed)
Build token utility and staking logic (testnet-first, security-focused)
Integrate smart contracts with off-chain systems (APIs, indexers, dashboards)
Write automated tests and conduct basic security reviews
Support on-chain analytics, event indexing, and data pipelines
Document contract behavior, assumptions, and upgrade paths
Required Skills & Experience
Strong proficiency in Solidity and EVM fundamentals
Solid understanding of Ethereum architecture, gas mechanics, and transactions
Experience with smart contract testing frameworks (Hardhat, Foundry, or Truffle)
Familiarity with web3 libraries (ethers.js, web3.js)
Knowledge of common smart contract vulnerabilities (reentrancy, overflow, access control)
Comfortable working with Git and code reviews
Nice to Have
Experience with Layer 2s (Arbitrum, Optimism, Base, Polygon)
Familiarity with tokenomics modeling (emissions, incentives, staking design)
Exposure to on-chain analytics (The Graph, Dune, custom indexers)
Backend experience (Node.js, Python)
Prior security auditing or formal verification exposure
What We Care About
Engineering discipline over hype
Clear documentation and reproducibility
Security-first mindset
Ability to reason about incentives and edge cases
Comfort working in early-stage, research-heavy environments
For Students / Interns (OPT / CPT Eligible)
Project-based, academically aligned work
Testnet and simulation-focused development
No fundraising, token sales, or solicitation activities
Responsibilities aligned with computer science, engineering, or blockchain coursework
What We Offer
Work on real blockchain infrastructure — not demos
Mentorship and exposure to AI + macro research systems
Flexible work structure (remote-friendly)
Opportunity to grow into long-term or paid roles as we scale
Work arrangement
