1. Role Overview

Ensures blockchain network infrastructure stays alive and stable 24/7. You manage cloud servers, run validator nodes or RPC nodes yourself, and organize automated deployment pipelines (CI/CD) for dApps.

2. Daily Work

What you will actually do most weeks

Building, configuring, and maintaining RPC Nodes and Validator Nodes (Ethereum, Solana, Cosmos, etc.) on Linux servers

Managing cloud infrastructure using Terraform, Docker, and Kubernetes

Monitoring system health, network latency, and memory usage using Grafana and Prometheus

Managing CI/CD pipelines in GitHub Actions for automated testing and smart contract / frontend deployment

Expected Outputs & Deliverables

Blockchain node infrastructure with 99.99% uptime

Smooth and fast automated deployment pipelines (CI/CD pipelines)

System monitoring and alerting systems for server/node failures

3. Skills & Tools

Must-Have Skills

Advanced Linux system administration and bash scripting

Mastery of Docker, Kubernetes, and Infrastructure as Code tools (Terraform / Ansible)

Understanding of blockchain P2P network architecture, node synchronization (snap/fast sync), and data pruning

Experience with cloud providers (AWS, GCP, DigitalOcean) and bare-metal providers (Hetzner, OVH)

Ecosystem Tools

Docker / KubernetesTerraform / AnsibleGrafana / PrometheusAWS / Hetzner / GCPLinux / Bash / Git

4. Proof-of-Work & Prep

Actionable Proof-of-Work

GitHub repository containing infrastructure configuration scripts (Terraform/Ansible) for deploying validator nodes

Public dashboard or metrics showcase demonstrating experience managing high-uptime infrastructure

Self-Study Prep

Learn Linux administration, Docker containerization, and basic cloud networking thoroughly
Practice running a testnet validator or archive node for an EVM chain locally or on a cloud VPS
Study how RPC providers like Infura, Alchemy, or QuickNode architect their load balancing

5. Apply & Interview

Application Strategy

Highlight experience in handling high-availability systems and running production blockchain nodes in your resume

Apply to infrastructure-focused Web3 companies or L1/L2 networks expanding their validator sets

Interview Prompts

"How do you configure a failover architecture for Ethereum RPC Nodes so that if one node experiences latency spikes, traffic automatically routes to a backup node?"

6. Guide Roadmap

Step 1

Linux & Cloud Fundamentals

Master Linux administration, Docker, and cloud infrastructure basics.

Step 2

Blockchain Node Management

Learn how to spin up, sync, and prune validator/RPC nodes for various networks.

Step 3

Infrastructure Automation

Use Terraform, Kubernetes, and Prometheus/Grafana to build robust scaling systems.

Step 4

Infrastructure Engineer Application

Apply to Web3 infrastructure providers, RPC services, or protocol validator teams.
