• Implement automated deployment and management pipelines using CI/CD and IaC best practices.
• Troubleshoot production issues across services and levels of the stack; contribute to post‑mortems and continuous improvement efforts.

Requirements

• 6+ years of experience in infrastructure or backend engineering, ideally with blockchain or crypto systems.
• Deep understanding of blockchain node architecture, syncing, and consensus mechanisms.
• Hands‑on experience managing blockchain clients (e.g., Geth, Reth, Jito‑Solana, etc).
• Proficiency in working with indexing frameworks (e.g., Tycho indexer or similar).
• Experience with containerization, orchestration (Docker, Kubernetes), and cloud infrastructure (AWS, GCP, or similar).
• Familiarity with Trusted Execution Environments (TEEs) such as Intel SGX, AWS Nitro Enclaves, or similar.
• Strong knowledge of Linux systems, networking, and observability tools (Grafana, Prometheus, etc).
• Scripting or programming proficiency in Python, Bash, Rust, or similar.
• Knowledge of blockchain data structures (e.g., Merkle Trees, state diffs).

Nice to Have

• Exposure to trading systems or quantitative finance environments.
• Contributions to open‑source blockchain infrastructure projects.
• Experience working in high‑availability or low‑latency environments.
