Descripción de la vacante

Aether Protocol in the United States is seeking a Solidity Engineer to design and implement core money-market contracts for the protocol. You will own Solidity delivery for the EVM money-market reference, including market registry logic, collateral and borrow accounting, rate models, and oracle interfaces.

Responsibilities include implementing hub, token, interest-rate, and governance contracts; encoding invariants; and writing Foundry tests and security-facing documentation for audits.

Formación

• Strong Solidity and EVM experience shipping or hardening DeFi protocols.
• Deep familiarity with money markets, collateral factors, oracles, and liquidation mechanics.
• Comfort with Foundry testing, gas-aware design, and audit handoff.
• Ability to reason about economic and security trade-offs before writing code.
• Clear written communication for design notes and review comments.

Responsabilidades

• Implement and refine Hub, AeToken, interest-rate, liquidation, and governance-related contracts
• Encode protocol invariants around borrow caps, account health, and economically sound liquidations
• Write Foundry-oriented unit, fuzz, and invariant tests for adversarial and edge-case behavior
• Prepare clean interfaces, upgrade/authority patterns, and documentation for security review
• Identify and reject unsafe patterns from the reference MVP before they reach production paths

Solidity Engineer Solidity Engineer

Design and implement core money-market contracts for Aether Protocol—Hub, AeToken markets, interest models, liquidation paths, and audit-ready test coverage.

You will own Solidity delivery for Aether’s EVM money-market reference and help move it toward production standards. The work spans market registry logic, collateral and borrow accounting, rate models, oracle interfaces, and incentive distribution in AETH.

Responsibilities

• Implement and refine Hub, AeToken, interest-rate, liquidation, and governance-related contracts


• Encode protocol invariants around borrow caps, account health, and economically sound liquidations


• Write Foundry-oriented unit, fuzz, and invariant tests for adversarial and edge-case behavior


• Prepare clean interfaces, upgrade/authority patterns, and documentation for security review


• Identify and reject unsafe patterns from the reference MVP before they reach production paths

Requirements

• Strong Solidity and EVM experience shipping or hardening DeFi protocols


• Deep familiarity with money markets, collateral factors, oracles, and liquidation mechanics


• Comfort with Foundry (or equivalent) testing, gas-aware design, and audit handoff


• Ability to reason about economic and security trade-offs before writing code


• Clear written communication for design notes and review comments

Nice to have

• Experience with Compound-style architectures or similar lending protocols


• Exposure to Solana program design for a future architecture mapping


• Prior work preparing contracts for external security audits
