Mission: Fortify sovereign infrastructure for a player-owned economy where downtime = lost kingdoms.
Responsibilities:
Architect zero-downtime multichain ops (Arbitrum/BASE rollups, fraud-proof autoscaling)
Design self-healing node clusters that counter NFT minting DDoS attacks in <5ms
Embed on-chain circuit breakers to halt exploits before they drain $CORE liquidity
Turn Discord FUD storms into infra stress metrics via custom LLM pipelines
You’re a Fit If:
You’ve slashed gas costs by 30%+ in past DeFi/GameFi projects (prove it)
Your idea of “monitoring” includes MEV bot behavior and DAO vote latency
You’ve built systems where “chaos testing” means simulating chain splits during PvP wars
You see player rage-quits as a critical infrastructure metric
Compensation:
Base + % of rescued gas fees (paid in $CORE)
NFT “Backbone” Pass (permanent % of protocol revenue)
DAO voting power scaled to uptime milestones (*99.99% SLA = veto rights*)
