Smart Contract / Blockchain Engineer
Full-time • Remote
Fix Crypto's Broken Engine with Exchequer
Crypto's promise of permissionless innovation is being choked by a broken market structure. Extractive gatekeepers, unsustainable liquidity schemes, and flawed incentives are crippling builders and holding back the entire ecosystem. At Exchequer, we're not just complaining about it – we're re-engineering crypto's financial foundation from the ground up. We build robust, sustainable infrastructure that empowers projects, bypasses middlemen, and unlocks true value creation.
The Role: Design, Build, and Secure Crypto's Future Foundation
As a Smart Contract / Blockchain Engineer at Exchequer, you will be at the heart of our mission. You will help design, build, and secure our core financial primitives and protocols. Your work will directly contribute to creating a fairer, more transparent, and truly decentralized future by developing the foundational smart contracts that power sustainable liquidity and treasury solutions for crypto projects.
Key Responsibilities:
- Design, develop, test, and deploy high-quality, secure, and efficient smart contracts that form the core of Exchequer's offerings.
- Collaborate with the founding team on protocol architecture, financial modeling, and mechanism design.
- Conduct rigorous security audits, participate in code reviews, and implement best practices for smart contract safety.
- Research and integrate new blockchain technologies, L2 solutions, and DeFi primitives.
- Contribute to technical documentation and explain complex concepts to both technical and non-technical audiences.
- Stay at the forefront of smart contract development, security vulnerabilities, and emerging trends in the blockchain space.
Who We're Looking For:
- Proven experience in designing, developing, and deploying complex smart contracts on EVM-compatible chains (e.g., Ethereum, Polygon, Arbitrum) or other relevant L1s/L2s.
- Proficiency in Solidity is essential; experience with other smart contract languages (e.g., Rust, Vyper) is a plus.
- Deep understanding of blockchain fundamentals, consensus mechanisms, token standards (ERC-20, ERC-721, ERC-1155, etc.), and DeFi protocols.
- Strong knowledge of smart contract security principles, common attack vectors, and mitigation techniques (e.g., reentrancy, oracle manipulation).
- Experience with smart contract development tools and frameworks (e.g., Hardhat, Foundry, Truffle).
- A passion for DeFi and a belief in crypto's potential to reshape finance.
- Ability to work independently in a remote setting, manage your own time effectively, and collaborate with a distributed team.
- A rigorous, truth-seeking mindset with a commitment to building mathematically sound and practically effective solutions.
