About us Aave Labs began with a simple question: how do we make financial services like borrowing, saving, and earning more accessible globally? We built the Aave Protocol, now the world's largest and most trusted onchain lending market, connecting decentralized finance with individuals, traditional finance, and fintech. Today, we build trusted, high-quality products that expand access to lending, credit, and savings globally We hold a high bar for quality and craftsmanship.

Trust depends on it. We're a integral team building products people can actually use, turning complex technology into something simple and reliable. We're hiring a Staff Backend Engineer to build the backend infrastructure behind Aave App, a consumer savings app that makes onchain financial products simple, secure, and intuitive.

The role focuses on the systems between blockchain protocols and the consumer experiences built around them. This includes account and wallet services, transaction orchestration, high-reliability blockchain indexing, balances and yield data, funding and withdrawal flows, notifications, and performant, well-documented APIs for mobile and web clients.
