Fully Remote | 13:00-19:00 GMT+1 | $50 ~ $100 per hour
What You’ll Do
* Architect, implement, and deploy **secure smart contracts** for an on-chain Play-to-Earn GameFi ecosystem
* Lead contract design decisions with a focus on robustness, auditability, gas efficiency, and resilience to attack vectors
* Mentor/junior developers: perform code reviews, establish standards, best practices in security & testing
* Collaborate cross-functionally with game designers, backend, QA, and security teams to align smart contract features with product roadmap
Must-Haves:
* 4+ years hands‐on experience developing & deploying smart contracts (Solidity / EVM or equivalent) in production environments
* Track record of writing secure contracts, familiarity with common vulnerabilities (reentrancy, integer over/underflow, front-running, flash loans, etc.)
* Experience with audits, formal verification, fuzz testing, or other advanced contract assurance methods
* Strong test suite / CI workflow skills; comfortable using tools like Hardhat, Foundry, Truffle etc.
* Solid understanding of GameFi mechanics and how on-chain economics work
Nice to Have:
* Experience on multiple EVM chains or Layer-2 / sidechains
* Knowledge of cross-chain bridges, oracles, NFTs, tokenomics design
* Contributions to open-source security tooling or prior audit reports or published code you’re proud of
Compensation & Perks
* Senior Rate: $50–100 / hour
* Fully remote, global team
* Flexible hours (must overlap 13:00-19:00 GMT+1)
* Ownership of what you build; influence over architecture, security, and standards
How to Apply ( Important: Applications without the requested materials will not be considered )

* Your GitHub profile (real, established, not brand-new / fake)
* At least one relevant link (projects, audits, open-source contributions, portfolio)
(Don’t send “Hi” only. I don’t respond to that.)
