Context for the Candidates:
Blockchain engineers are tasked with building secure, scalable, and high-performance decentralized applications. This discussion focuses on how to utilize key technologies—Node.js, Rust, Go, TypeScript, Ethers.js, viem, and Hardhat—in smart contract and blockchain system development, while addressing the practical challenges that arise in such projects.
Key Discussion Points:
• How do you integrate Node.js, Rust, Go, and TypeScript in blockchain-backed applications?
• Discuss the trade-offs between using Rust or Go for performance-critical blockchain services.
• What are the key challenges in ensuring the security and scalability of smart contracts using tools like Ethers.js, viem, and Hardhat?
• How do you approach testing, debugging, and deploying smart contracts in a decentralized environment?
• Share best practices for gas optimization, contract upgradability, and backend scalability.
Evaluation Criteria:
1. Technical Knowledge:
• Strong knowledge of Node.js, Rust, Go, and TypeScript with practical experience in blockchain development.
• Proficiency in Ethers.js, viem, Hardhat, and smart contract lifecycle (development, testing, deployment).
• Understanding of security best practices, performance optimizations, and scalability in decentralized systems.
2. Problem-Solving and Integration Skills:

We are open to talking as long as you have good judgment, great clarity, align with our values and have a strong track record of thoughtful work
- Understand the fundamentals of building and integrating APIs and secure systems. Bonus if you know a bit about blockchains and protocols
- You can be strong on the backend, front-end, or can dabble everywhere. We want you to play to your strengths and will provide enough opportunities to learn and do things outside of your comfort zone
Pay and benefits We offer a solid, competitive package (including early-stage equity) that is location agnostic. We give you the flexibility to choose the split between cash and equity.
