Blockchain Engineering Intern

About the Blockchain Engineering Intern Role at SKXYWTF

World Trade Factory (SKXYWTF) is pioneering next-generation digital infrastructure at the intersection of blockchain, AI, and global markets. We are seeking a Blockchain Engineering Intern to contribute to the design, development, and testing of smart-contract-based systems and supporting infrastructure within an educational, research-driven, and production-oriented environment. This role prioritizes engineering discipline, security, and robust architecture over speculative hype.

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, focusing on testnet development and security.
• Integrate smart contracts with off-chain systems, including APIs, indexers, and dashboards.
• Write automated tests and conduct fundamental security reviews.
• Support on-chain analytics, event indexing, and data pipelines.
• Document contract behavior, assumptions, and potential upgrade paths.

Required Skills & Experience

• Strong proficiency in Solidity and fundamental understanding of EVM.
• Solid grasp of Ethereum architecture, gas mechanics, and transaction processes.
• Experience with smart contract testing frameworks like Hardhat, Foundry, or Truffle.
• Familiarity with web3 libraries such as ethers.js or web3.js.
• Knowledge of common smart contract vulnerabilities including reentrancy, overflow, and access control issues.
• Comfortable working with Git for version control and participating in code reviews.

Nice to Have

• Experience with Layer 2 scaling solutions (e.g., Arbitrum, Optimism, Base, Polygon).
• Familiarity with tokenomics modeling, including emissions, incentives, and staking design.
• Exposure to on-chain analytics tools like The Graph, Dune, or custom indexers.
• Backend development experience (Node.js, Python).
• Prior exposure to security auditing or formal verification processes.

What SKXYWTF Cares About

• Demonstrated engineering discipline.
• Clear documentation and reproducibility in your work.
• A security-first mindset in all development.
• Ability to reason about incentives and edge cases in blockchain systems.
• Comfort working within early-stage, research-heavy environments.

For Students / Interns (OPT / CPT Eligible)

• Project-based, academically aligned work.
• Focus on testnet and simulation-driven development.
• No involvement in fundraising, token sales, or solicitation activities.
• Responsibilities directly aligned with computer science, engineering, or blockchain coursework.

What We Offer

• Opportunity to work on real blockchain infrastructure, not just demos.
• Mentorship and exposure to cutting-edge AI and macro research systems.
• Flexible and remote-friendly work structure.
• Potential for growth into long-term or paid roles as SKXYWTF scales.
