About the role

  • First responder for EVM product alerts: investigate issues, reproduce behavior, partner with internal teams, and maintain system resilience.
  • Meet client SLAs by quickly identifying, analyzing, and resolving incidents.
  • Decode transactions, logs, and traces; reproduce behavior using Foundry/Hardhat and lightweight PoCs.
  • Collaborate with protocol, backend, and risk teams during incident response and "war rooms".
  • Maintain and improve playbooks, dashboards, and alerting systems.
  • Monitor upstream changes (EIPs, dependencies, oracle/bridge updates) and highlight product risks.
  • Deliver concise incident briefs and post-mortems with actionable recommendations.

Requirements

  • Strong EVM expertise, including Solidity and Python.
  • Advanced debugging skills with tools like Foundry/Anvil, Hardhat, Tenderly, and Phalcon.
  • Excellent written communication, structured problem-solving, and composure in high-pressure situations.
  • Flexibility to participate in a nights/weekends on-call rotation.
  • Prior Web2 on-call/SRE experience (production incidents, paging, post-mortems).
  • Experience with Dune/SQL or The Graph for fast data analysis.
  • Familiarity with Chainlink and other oracles, cross-chain/bridge flows, L2 stacks (Optimism, Arbitrum, etc.), or non-EVM chains (e.g., Solana).
  • Previous incident response or security research experience.
  • Ability to decode transactions, logs, and traces; reproduce behavior using Foundry/Hardhat and build lightweight PoCs.
