Software Engineer

Role: Senior Smart Contract Engineer (Remote – Europe / U.S. East Coast)

What They’re Looking For

They are seeking a security-minded smart contract engineer with deep experience in designing and reviewing ERC-4626 vault architectures. This role involves building production-grade smart contracts, conducting security reviews, and collaborating closely with auditors and other protocol engineers to ensure best-in-class security for users.

Key Responsibilities

• Architect, implement, and optimize ERC-4626 tokenized vaults and strategy contracts.
• Conduct rigorous internal reviews and support external audits.
• Collaborate with product and engineering teams to define vault specifications, risk parameters, and security requirements.
• Build robust test suites, fuzzers, and CI pipelines to catch vulnerabilities early.
• Stay ahead of the curve on new attack vectors, DeFi exploits, and security research.

Qualifications & Skills

• Strong experience with Solidity and ERC-4626 vault design (or similar vault standards).
• Deep understanding of common DeFi attack vectors and mitigation strategies.
• Hands-on experience working with security tools like Slither, Echidna, or Foundry fuzzers.
• Proven track record shipping production smart contracts that handle significant TVL.
• Strong written communication skills for documentation and audit preparation.

Bonus Points

• Experience with cross-chain protocols or bridges.
• Familiarity with MPC wallets, multisig custody setups, or institutional onboarding flows.
• Background in formal verification or security research.

Why This Role Stands Out

• Fully remote, with a team distributed across Europe and the U.S. East Coast.
• Work on security-critical infrastructure used by institutional investors.
• Opportunity to own key components of a growing DeFi platform and influence its architecture.
• Join a team that prioritizes security, transparency, and long-term sustainability over hype cycles.
