This role emphasizes autonomy, strategic impact, and building scalable frontend infrastructure while delivering clear, trustworthy user experiences across financial products.

Qualifications

• Strong proficiency in React, TypeScript, CSS and system design and architecture.
• Deep experience with frontend performance engineering - measuring it, diagnosing it, and fixing it.
• Strong command of Next.js patterns for data loading, fetching and caching, and experience handling server rendering and streaming data to the frontend.
• Deep experience with component-driven design systems and component design patterns, and building for consistency at scale.
• The product sense to work without a detailed brief - you can identify what needs to be solved, not just how to solve it.

Responsibilities

• Work autonomously across our web products, building high-quality UI with a strong point of view on how it should feel, function, and perform.
• Own and evolve complex, reusable components within the Aave design system - setting the standard for quality and consistency.
• Set the bar for frontend performance, from data loading, fetching and caching patterns through to server rendering and streaming.
• Bring product-level thinking to everything you work on - understanding user needs, business context, and technical constraints, whilst balancing them well.
• Collaborate with our talented designers, engineers, and product leads to bring clarity to ambiguous problems. Help raise the bar for the team through the quality of your work and the way you approach problems.
