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:

• How candidates approach integrating smart contract solutions with backend services using Node.js, Rust, Go, and TypeScript.

• Solutions proposed for common challenges in blockchain projects such as gas fees, security vulnerabilities, and system bottlenecks.

3. Experience and Expertise:

• Minimum of 2 years of IT experience, including hands-on development with the specified technologies.

• Practical knowledge of blockchain architecture, consensus mechanisms, and decentralized application deployment.

4. Innovation and Critical Thinking:

• Candidates’ ability to think creatively about system architecture, proposing scalable and secure solutions for blockchain-based applications.

• Discussion on the future potential of blockchain technology and how the tech stack can evolve.

5. Communication and Team Collaboration:

• Clear articulation of technical challenges and how to address them in a team setting.

• Ability to lead or contribute to discussions in a way that encourages collaboration and team-driven problem-solving.

What you need to have:

You have 5 years or more of Backend end development experience with expertise in designing and implementing high-performance applications.

Worked with and built high-performance products using Node Js/GoLang/ Python and have seen the product evolution cycle from PoC to Production

You have a deep understanding of design principles and can rightly judge/implement solutions to complex problems

You are capable of writing high-quality code that conforms to the standards and best practices in a particular language/framework.

You have experience building a product using a mainstream library or framework.

You love to own end to end responsibility, starting from defining the problem statement (either yourself or alongside your peers), development (PoC if needed), testing, releasing in staging & then production environment, and finally monitoring.

Previous work experience in product-based startups

Experience building for products that have scaled and have seen the product evolution
