Job Description

As a Senior Solidity Engineer, you will be responsible for designing and implementing secure, efficient, and scalable smart contracts that enable users to mint and stake USDe. This role involves developing automated delta-neutral derivative strategies within smart contracts, leveraging customised algorithms to identify and capture optimal arbitrage opportunities across decentralized finance (DeFi) platforms and centralized derivative exchanges. You will collaborate with custody and exchange providers to establish secure, auditable connectivity to various financial venues through our smart contract infrastructure. Additionally, you will contribute to the evolution of the core stablecoin product by envisioning and developing new features, such as money market integrations and internal automated market maker (AMM) functionality. The position requires a deep understanding of DeFi protocols and the ability to innovate within the constraints of blockchain technology to push the boundaries of decentralized financial design.

Key Responsibilities

Architect and deploy secure, high-performance smart contracts for USDe minting, staking, and derivative strategies using Solidity.
Develop and maintain delta-neutral derivative strategies that dynamically execute arbitrage opportunities across DeFi and centralized exchanges.
Collaborate with custody teams to integrate secure, compliant connectivity protocols with third-party financial venues.
Design and implement scalable solutions for money market systems and internal AMM mechanisms within the stablecoin product.
Conduct rigorous security audits and vulnerability assessments to ensure contract robustness against exploits and attacks.
Optimize gas efficiency and transaction throughput for smart contract operations on Ethereum and other blockchain networks.
Work closely with quantitative engineers to translate complex financial models into executable smart contract logic.
Lead the development of cross-chain compatibility features for multi-venue arbitrage strategies.
Document technical specifications and provide clear explanations for contract functionality to support team collaboration.
Stay updated on emerging DeFi trends and blockchain innovations to continuously improve contract design and implementation.

Job Requirements

Proven expertise in Solidity development with a minimum of 5 years of experience in blockchain engineering.
Deep understanding of Ethereum blockchain architecture, including gas mechanics, consensus protocols, and smart contract best practices.
Strong background in DeFi protocol design, with experience in creating automated market maker systems, yield aggregators, or liquidity protocols.
Advanced knowledge of cryptographic principles and secure coding practices to prevent vulnerabilities in smart contracts.
Experience with cross-chain solutions and interoperability frameworks for connecting multiple financial platforms.
Ability to analyze complex financial strategies and translate them into efficient, delta-neutral smart contract implementations.
Excellent problem-solving skills with a focus on optimizing performance, security, and cost-efficiency in blockchain applications.
Collaborative mindset with experience in working with cross-functional teams, including product managers, quantitative analysts, and DevOps engineers.
Strong communication skills to articulate technical concepts to non-technical stakeholders and mentor junior engineers.
Proficiency in version control systems (e.g., Git) and CI/CD pipelines for automated testing and deployment of smart contracts.
Experience with blockchain development tools such as Truffle, Hardhat, and Remix for contract compilation and debugging.
Knowledge of decentralized exchange (DEX) protocols and centralized exchange APIs for integration with trading venues.
Ability to design and implement modular smart contract systems that support future product expansion and feature development.
Strong analytical skills to evaluate market data and optimize arbitrage strategies for maximum efficiency and minimal risk.
Experience with formal verification tools for ensuring the correctness and security of smart contract code.
