Senior Solidity Developer Needed for Hybrid Crypto Poker Platform (Escrow + Payouts + Fairness)

We’re building a real-money poker product with a hybrid architecture: gameplay runs off-chain for speed, while money movement and final settlement happen on-chain. We need a senior blockchain engineer who has already shipped secure contracts in production and can work closely with backend/frontend developers.

You’ll be responsible for designing and implementing the contract layer for buy-ins, pot escrow, and automated payout distribution. You should also be comfortable integrating wallet flows, handling edge cases in transaction processing, and building with audit readiness in mind.

What we need you to own:
Solidity contracts for deposit handling, table escrow, and winner payouts
Integration pattern for off-chain game results -> on-chain settlement
Wallet-based user flow support (MetaMask / EVM wallets)
Verifiable randomness integration (Chainlink VRF preferred)
Security hardening, test coverage, and gas optimization

Must-have experience:
Proven production Solidity work on EVM chains (Ethereum/Polygon/BSC)
Strong understanding of reentrancy, access control, oracle risk, and payout safety
Hands-on with Hardhat or Foundry, OpenZeppelin, and test/fuzz workflows
Experience with event-driven backend integration (Node.js stack is a plus)

Nice to have:
Gaming, poker, betting, or escrow contract background
Experience preparing systems for external audits
Familiarity with operational handling of failed txs and reorgs

When applying, please include:
links to contracts you’ve deployed,
your exact role on those projects, and
how you would structure 1v1 poker escrow + settlement in an MVP.
