Senior Solidity/EVM Developer — Proof of Dev

Proof of Dev is a Web3 reputation platform that verifies meaningful blockchain engineering activity through transparent evidence instead of self-reported resumes.

It connects developer identity with verifiable proof, including GitHub contributions, deployed and verified smart contracts, releases, security reviews, attestations, and long-term maintenance. Our mission is to help developers, recruiters, DAOs, grant programs, and blockchain teams answer: **What evidence proves that this developer has done meaningful work?**

We are seeking a Senior Solidity/EVM Developer to improve the platform’s smart contracts, on-chain attestations, wallet analysis, and blockchain integrations.

## Responsibilities

* Develop and review Solidity contracts for attestations, reputation records, and developer credentials.
* Improve wallet, deployment, and contract-verification analysis across EVM networks.
* Integrate Etherscan, RPC providers, backend APIs, and GitHub proof signals.
* Implement reliable transaction submission, confirmation, retries, and monitoring.
* Write unit, integration, fuzz, and invariant tests.
* Improve architecture, security, scalability, gas efficiency, and maintainability.
* Document technical decisions clearly.

## Required Skills

* Strong Solidity, EVM, Foundry, or Hardhat experience.
* Smart-contract security, access control, upgradeability, and gas optimization.
* TypeScript/Next.js backend experience.
* ethers.js or viem, RPC APIs, wallets, signatures, nonces, and transaction lifecycle.
* Production contract, audit, identity, attestation, reputation, or fintech experience is preferred.
