Key Responsibilities

Blockchain Infrastructure

• Deploy, configure, and maintain core blockchain infrastructure such as full nodes, validator nodes, and indexers (e.g., Ethereum, Solana, Bitcoin)
• Monitor node uptime, sync health, disk usage, and networking performance
• Set up scalable RPC endpoints and archive nodes for dApps and internal use
• Automate blockchain client upgrades and manage multi-region redundancy
  
  
  

Web3 Application DevOps

• Manage the deployment and hosting of Web3 frontends, smart contract APIs, and supporting services
• Create and maintain CI/CD pipelines for frontend apps, smart contracts, and backend services
• Integrate deployment workflows with Vercel, GCP Cloud Run, AWS Lambda, or Azure App Services
• Securely handle smart contract deployment keys and environment configurations
  
  
  

Cloud Infrastructure

• Design and manage infrastructure across AWS, GCP, and Azure based on performance, cost, and scalability considerations
• Use infrastructure-as-code (e.g., Terraform, Pulumi, CDK) to manage provisioning and automation
• Implement cloud-native observability solutions: logging, tracing, metrics, and alerts
• Ensure high availability and disaster recovery for critical blockchain and app services
  
  
  

Security, Automation, and Compliance

• Implement DevSecOps best practices across cloud, containers, and CI/CD
• Set up secrets management and credential rotation workflows
• Automate backup, restoration, and failover for all critical systems
• Ensure infrastructure meets required security and compliance standards
  
  
  

Preferred Skills And Experience

• Experience running validators or RPC services for Proof-of-Stake networks (Ethereum 2.0, Solana, Avalanche, etc.)
• Familiarity with decentralized storage systems like IPFS, Filecoin, or Arweave
• Understanding of indexing protocols such as The Graph or custom off-chain data fetchers
• Hands-on experience with Docker, Kubernetes, Helm, or similar container orchestration tools
• Working knowledge of EVM-compatible toolkits like Foundry, Hardhat, or Truffle
• Experience with secrets management (Vault, AWS SSM, GCP Secret Manager)
• Previous exposure to Web3 infrastructure providers (e.g., Alchemy, Infura, QuickNode)
