Key Responsibilities

• Architect, develop, test, and maintain production-grade Rust systems.
• Design scalable distributed and backend architectures.
• Contribute to blockchain/Web3 protocol and infrastructure development.
• Optimize system performance, memory usage, concurrency, and reliability.
• Investigate complex technical and production issues.
• Participate in architecture and technical design decisions.
• Review code and establish strong engineering standards.
• Build secure and maintainable software following modern development practices.
• Work with engineers across backend, AI, and blockchain-focused initiatives.
• Mentor junior and mid-level engineers through code reviews and technical guidance.
• Take ownership of features and technical components from design through production.
• Continuously evaluate new technologies and improvements within the Rust/Web3 ecosystem.
