Hi! I’m looking for a senior smart contract developer who doesn’t just write code — but understands protocol architecture, makes strong technical decisions, and wants to influence the product rather than sit in a backlog on an outsourced team. This is serious Web3 product development — no “toy” testnets or endless refactoring of someone else’s contracts. We’re solving real problems at the intersection of DeFi, governance, and Layer 2 infrastructure.
What you'll be doing:
- Develop and optimize smart contracts (Solidity / Rust)
- Design protocols with security, efficiency, and transparency in mind
- Work closely with frontend, product, and audit teams
- Participate in architectural decisions, assess risks, balance gas cost and UX
What we’re looking for:
- Solid production experience with Solidity or Rust (not just pet projects)
- Excellent understanding of EVM and key tools (Hardhat, Foundry, ethers.js, etc.)
- Strong grasp of vulnerabilities: reentrancy, flash loans, oracle manipulation, etc.
- Background in DeFi, DAOs, governance, or Layer 2 is a strong plus
- Ability to write clean, efficient, gas-optimized code
- Good communication: we’re a distributed team — async collaboration matters
What we offer:
- Work with a global team where your opinion really matters
- A mission-driven product with real users and big ambitions
- Technical leadership that respects your time and doesn’t micromanage
- 100% remote setup with full flexibility
- Competitive salary and equity/token options — tailored individually
If you know what a well-written smart contract looks like and you're ready to build something meaningful — let’s talk. Message me directly and we’ll see where you can bring the most value.
Warm regards,
Alan Carpenter
