About the Role

We are hiring for a Blockchain Infrastructure Engineer to design, deploy, and optimize mission-critical blockchain infrastructure powering our trading operations. You will work at the intersection of distributed systems, low-latency engineering, and blockchain protocols — building robust, scalable systems to support node operations, data indexing, and secure computation.

Responsibilities

• Design and deliver stable, efficient, and scalable blockchain node infrastructure.
• Build and maintain indexing systems that feed on-chain data to trading systems with high reliability and low latency.
• Proactively monitor and optimize infrastructure for performance, uptime, and resource efficiency.
• Track and adopt new developments across blockchain ecosystems — including protocol upgrades, new client implementations, indexing frameworks, and ecosystem tools.
• Collaborate with cross-functional teams to deploy and operate Trusted Execution Environment (TEE) infrastructure in support of secure computation and private trading strategies.
• 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.
