- Component Libraries: Contributing to the creation and evolution of robust design systems to ensure consistency across consumer-facing dApps and internal administrative tools.
- AI-Native Workflow: Leveraging and establishing team standards for AI-assisted development (Cursor, Claude, or similar) to accelerate the production of high-quality, tested code.
- Stack Fluidity: Operating as a full-stack contributor with a frontend bias, comfortably navigating backend services (Node.js/Go) to ensure seamless API integration and system performance.
- Technical Rigor: Balancing rapid iteration with high standards for observability, performance profiling, and comprehensive testing (React Testing Library/Jest).
What They’re Looking For
- Frontend Expertise: Deep proficiency in Next.js, React, and TypeScript, specifically in the context of data-heavy, real-time applications.
- Transactional Experience: A background in Fintech, Payments, or Trading environments where UI performance directly impacts transactional integrity.
- Event-Driven Knowledge: Experience managing state in applications with high-frequency data streams and complex user flows.
- AI-First Approach: Active and proficient usage of AI-assisted coding tools as part of a daily production workflow to increase efficiency and output.
- Engineering Fundamentals: A strong understanding of secure coding practices, design patterns, and the ability to contribute to backend infrastructure when required.
