About Wildcat
Wildcat is an Ethereum protocol revolutionizing on-chain credit with an innovative, undercollateralized borrowing solution. Our mission is to lead this market by enabling borrowers to create, customize, and manage credit facilities in a more transparent, efficient, and secure environment. Borrowers can tailor their credit demand to suit their needs. Designed for sophisticated participants in both traditional finance (TradFi) and DeFi, Wildcat is committed to transforming on-chain credit and unlocking more efficient, customized solutions in decentralized finance.
Working for Wildcat
As a Full-Stack Developer, you will be driving the technical evolution of Wildcat’s undercollateralized lending platform. You’ll work across the front-end and back-end while integrating Ethereum smart contracts to deliver an intuitive, secure, and high-performance user experience. Leveraging your experience in agile development and DeFi best practices, you will play a central role in shaping the platform’s architecture, features, and scalability. You’ll collaborate closely with the founding team, product manager, and other developers to ensure Wildcat remains at the forefront of on-chain undercollateralized credit innovation.
Responsibilities
Front-End Development
- Build user interfaces using React/TypeScript, creating responsive and intuitive designs.
- Maintain code quality through modular architecture, consistent coding standards, and performance optimization.
- Collaborate with designers and product managers to refine user flows and deliver new features seamlessly.
Back-End Development
- Develop Node.js services to power Wildcat’s undercollateralized lending protocol.
- Create and optimize APIs (REST/GraphQL) and integrate databases (e.g., PostgreSQL, PouchDB) for efficient data handling.
- Contribute to infrastructure decisions, including evaluating serverless vs. containerized setups and refining CI/CD pipelines.
Testing Setup
- Establish robust testing strategies (unit, integration, end-to-end) for front-end and back-end components.
- Automate testing workflows using tools like Jest, React/Vue Testing Library, and ensure consistent coverage for critical DeFi logic.
- Champion security best practices, helping to identify vulnerabilities early in the development lifecycle.
Integration with Ethereum
- Leverage ethers.js or wagmi to integrate Solidity contracts into the web application, handling wallet connections and transaction flows.
- Use Hardhat or Foundry for local development, contract deployment, and thorough on-chain testing.
- Ensure stability and security in all on-chain interactions, collaborating closely with the protocol team to maintain reliable DeFi operations.
Requirements
- Proven Full-Stack Experience: 5+ years building production-grade applications across front-end (React/Vue) and back-end (Node.js, REST/GraphQL, PostgreSQL).
- Ethereum & Web3 Knowledge: Familiarity with Solidity contracts, EVM fundamentals, and libraries like ethers.js. Experience setting up local test environments (Hardhat/Foundry) is a plus.
- Security & DeFi Mindset: Ability to design and implement secure coding practices for high-stakes financial systems, including an understanding of undercollateralized lending risks.
- Testing & Deployment Proficiency: Comfortable with automated test frameworks (Jest, Hardhat/Foundry) and modern CI/CD pipelines (GitHub Actions, Netlify/Vercel, Docker).
- Agile & Self-Directed: Demonstrated ability to handle multiple priorities, propose solutions, and deliver results within an iterative, remote-first environment.
- Collaboration & Communication: Strong written and verbal communication in a distributed team (EU time zones). Proficiency in working cross-functionally with designers, product managers, and marketers.
- Technical Leadership & Mentorship: Experience making architectural decisions, reviewing code, and guiding less-experienced developers. Stay current on Ethereum and decentralized lending trends, bringing valuable insights to the team.
What We Offer
- Impact & Ownership: Influence the direction of an innovative DeFi protocol and see your contributions directly shape the Wildcat ecosystem.
- Cutting-Edge Work: Collaborate with seasoned experts in DeFi and TradFi at the intersection of blockchain, finance, and technology.
- Remote Flexibility: Join a globally distributed team with flexible work arrangements, primarily aligned with EU hours.
- Competitive Compensation: Receive a competitive salary (in crypto or fiat) and potential equity/token allocation based on company growth.
- Growth & Development: Access to ongoing learning opportunities and a front-row seat to the latest advancements in decentralized finance.
