Senior Smart Contract Engineer

$150k - $240k

Blockchain Game Alliance

We’re looking for a Senior Smart Contract Engineer to help us build secure and scalable blockchain systems powering decentralized gaming ecosystems.

You’ll work on smart contracts related to NFTs, digital assets, staking systems, token mechanics, marketplace infrastructure, and on-chain gameplay features. This role is ideal for someone who enjoys writing clean Solidity code, optimizing gas usage, and thinking deeply about blockchain security and protocol design.

You’ll collaborate closely with blockchain architects, backend engineers, and frontend teams to bring new Web3 products into production. We’re looking for engineers who can take ownership from concept to deployment and who understand the realities of shipping secure blockchain applications at scale.

You should be comfortable working with Solidity, Hardhat, Foundry, OpenZeppelin libraries, and modern smart contract development workflows. Experience working across Ethereum-compatible ecosystems is important, and familiarity with auditing practices or common exploit patterns is highly valued.

Candidates with experience in GameFi, NFT infrastructure, DeFi systems, or cross-chain integrations will stand out.

We’re fully remote and globally distributed, with compensation designed to compete with top-tier US-based Web3 companies.

**Compensation:** $150,000 – $240,000 USD
