I need an experienced Solidity engineer to take full ownership of our smart-contract layer—from initial design through main-net deployment. Your day-to-day work will include writing clean, upgradeable contracts, setting up automated test suites, running security checks with tools such as Hardhat, Foundry, Slither or MythX, and fine-tuning gas usage so our users pay as little as possible. You will collaborate directly with our front-end team; once a contract is ready, you’ll expose ABI endpoints, write simple integration docs and jump on a quick call if something breaks in staging. Expect regular code reviews on GitHub, coverage reports in CI, and at least one external audit before we push to production. What I’m looking for • Proven track record of ...
