Résumé du poste

CoinList is seeking a senior smart contract engineer to build and deploy Solidity contracts that integrate with asset providers. You will design system-wide onchain components, own security considerations, and collaborate with a small team reporting to the CTO in a fast-paced environment.

You will work on mainnet contracts, emphasize secure coding practices, and expand your skills toward Rust or Solana runtimes if desired, while supporting rapid delivery and high-quality code.

Qualifications

• 7+ years of professional experience, including at least 2 years of writing Solidity that reached production.
• Deep knowledge of the EVM, storage layout and packing, gas mechanics, memory vs calldata vs storage, ABI encoding, events and indexing.
• Proficiency with proxies and upgradeability, role-based access control, signature verification (EIP-712), replay protection, and reentrancy defenses.
• Comfort with security-focused workflows: testing, audit collaboration, and a robust testing workflow (Foundry/Hardhat) justified from first principles.

Responsabilités

• Ship contracts to mainnet.
• Design contract systems with clear boundaries, interfaces, storage layouts, and upgrade strategies.
• Own cryptographic and security decisions; participate in attacker-style thinking before shipping.
• Collaborate in a small team under the CTO to deliver high-quality onchain primitives.
• Support auditing and incident response processes, including fuzzing and invariant tests.
