Senior Blockchain Backend Engineer — EVM / Smart Contract Lead

We're building the next-generation decentralized prediction market — fast, transparent, and community-driven. We’re re-imagining on-chain speculation with real utility and fun — a platform where users can create, trade, and settle markets on any event with real-time speed and gamified UX.

We’re now looking for a world-class backend and smart-contract developer to take full ownership of the EVM backend architecture and program design — from protocol logic to APIs, data indexing, and live on-chain settlement.

What You’ll Build

Core prediction market protocol (smart contracts, liquidity logic, resolution mechanisms).

Backend infrastructure for real-time data updates , on-chain / off-chain syncing, and analytics.

Secure APIs for frontend & partner integrations.

Event-based oracles & automated market creation flows.

Staking, settlement, and yield distribution modules.

Admin and governance layer for market validation.

CI / CD and deployment for testnet → mainnet rollout.

You Should Have

5+ years backend or blockchain engineering experience (Node.js, Go, or Rust).

3+ years of EVM-based smart-contract development (Solidity, Hardhat, Foundry).

Deep understanding of DEX / AMM mechanics, liquidity pools , and market resolution logic .

Proven experience deploying and managing smart contracts on Base, Polygon, or Ethereum mainnet .

Familiarity with event indexing (The Graph, custom indexers, oracles).

Experience building secure APIs, WebSockets, caching layers , and on-chain data pipelines .

Proficiency in PostgreSQL , Redis , AWS / GCP , and Docker / Kubernetes .

Solid grasp of security, gas optimization, multisig flows , and upgradeable contracts.

Bonus : prior work on prediction markets, perpetuals, or DeFi protocols .

Nice-to-Haves

Experience integrating with Chainlink, Pyth, or UMA oracles.

Familiarity with on-chain verification, dispute systems , or governance frameworks (OpenZeppelin) .

Background in data streaming , Web3 analytics , or real-time trading UIs .
