Company Description:
Winnables.com is on a mission to re-imagine iGaming through full on-chain transparency. We believe players deserve provably fair odds, transparent math, and no black-box RNGs. Every spin and ticket purchase is recorded immutably on Ethereum, so anyone can audit the outcome, track prize pools, or even build their own analytics on top of our contracts.
All of our games are designed and engineered 100% in-house by a small, senior team that blends game design, cryptography, and smart-contract security. We currently operate two flagship experiences:
Raffles – transparent prize drawings where every ticket lives on-chain, letting players verify fairness before and after the draw.
Loot Packs – blockchain-powered loot boxes that reveal randomized rewards with engaging pack-opening animations.
We’re still just getting started. The roadmap is full of green-field challenges—and real, measurable impact on an industry ripe for change. Join us and help craft the next generation of fair, fun, and truly player-owned gaming.

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*)
