What We Expect

  • Core Skills : Proficiency in C, C++, Python, GCP, and AWS infrastructure.

  • Problem Solver : Willingness to troubleshoot and resolve issues related to Ethereum nodes and infrastructure.

  • Design, deploy, and monitor secure PoS staking infrastructure.
  • Troubleshoot networking, consensus, and node operation issues.
  • Support internal development teams by providing a reliable blockchain backend.

    • Required Qualifications

  • 1-2+ years of experience in a blockchain infrastructure or Ethereum-focused role.
  • Proven understanding of PoS consensus and Ethereum node operations.
  • Experience with private Ethereum networks (e.g., configuring genesis files, bootnodes, enode management).
  • Proficiency in Linux environments, scripting (Bash / Python), and using cloud platforms (AWS, GCP).
  • Familiarity with networking concepts, TLS, firewalls, VPNs, etc.
  • Strong understanding of blockchain security principles.

    • Nice to Have
