Responsibilities:

📍Integration of Off-Chain and On-Chain Systems: Build and maintain infrastructure to connect backend services with blockchain networks. 📍Ensure smooth interactions between off-chain APIs and on-chain data in a scalable environment 📍Optimizing Blockchain Operations: Develop solutions to optimize gas usage for Ethereum and compute unit usage for Solana. Ensure that transactions are as cost-efficient as possible. 📍Code Security and Auditing: Conduct in-depth reviews of smart contract code to identify vulnerabilities. Collaborate with security auditors and implement necessary fixes to meet the highest security standards. 📍Testing and Validation: Write and execute comprehensive test cases to validate off-chain interactions. Simulate edge cases and identify potential failures before production deployment.

Skills:

📍Blockchain Expertise (Ethereum/Solana): Strong understanding of the Ethereum and Solana ecosystems, including their programming models (e.g., Solidity, Anchor, or Rust), transaction lifecycles, and consensus mechanisms. 📍Backend Development: Proficient in backend technologies such as Rust and Go. Experience building robust and scalable backend services that integrate with blockchain. 📍Database Management: Experience working with databases, especially those used in blockchain environments (e.g., Postgres for metadata or indexing). 📍API Development and Integration: Skilled at creating and consuming REST or gRPC APIs to bridge blockchain functionality with user-facing applications. 📍Problem-Solving and Debugging: Strong ability to debug blockchain-related issues, analyze transaction failures, and identify solutions to complex challenges in distributed environments.
