Protocol
Smart Contract Engineer (Hardhat)
Support audits with Hardhat-first Solidity analysis — fork tests, scenario scripts, and verification flows that prove findings on client code.
Remote
Fully remote with scheduled pairing during design, audit, and release windows. Timezone flexible if you can overlap with Protocol for critical reviews.
Compensation
Competitive cash + meaningful founding equity
About the role
This role is for a senior Solidity engineer who ships contracts in Hardhat day-to-day: expressive TypeScript tests, mainnet forks, upgrade scripts, and clean verification flows. You will own protocol features end to end inside the Hardhat workspace — distinct from our Foundry-leaning Smart Contract Engineer track and from the Hardhat tooling role that builds the platform itself.
Responsibilities
- Implement Solidity contracts for settlement, attestation anchors, and related protocol surfaces in Hardhat
- Write rigorous Hardhat + TypeScript test suites, including fork-based integration and upgrade path coverage
- Own deploy, simulate, and verify workflows for networks we support — with reproducible scripts and clear runbooks
- Collaborate with security reviewers to triage findings and land remediations without slowing the roadmap
- Raise the standard for readable contracts, explicit invariants, and PR-level threat notes
Requirements
- Senior Solidity ability with Hardhat as a primary professional toolchain
- Strong TypeScript testing and scripting skills inside Hardhat projects
- Production experience deploying and verifying contracts across environments
- Security-minded review habits — you catch footguns before they become findings
- Clear written communication for specs, rollout plans, and audit responses
Nice to have
- Hardhat plugins, custom tasks, or advanced network configuration experience
- Familiarity with OpenZeppelin upgrades, proxies, and multisig operations
- Exposure to institutional / custody / settlement domains
- Comfort collaborating with Foundry users in a multi-toolchain repo
Benefits
- Meaningful founding equity
- Flexible PTO and remote-first culture
- Budget for audits, Hardhat/cloud forks, and security conferences
- Home-office stipend and hardware signing kit
- Health coverage as we formalize benefits
- Optional team gatherings in hub cities
