Job Description

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
 
Our culture
 
We build trusted products that help people access and discover economic opportunities.
 
We hold a high bar for quality and craftsmanship. No detail is too small. Trust depends on it.
 
We’re a global team building products people can actually use, turning complex technology into something simple and reliable.
 
We stay aligned, move quickly, and think long term, while keeping teams lean and focused on impact.
 
About the role

We're hiring a Staff Backend Engineer to work with a small and highly technical team building the infrastructure behind new DeFi protocols and vault products at Aave Labs.

The role focuses on the systems between onchain protocols and the applications built around them. This includes **vault management and curation systems, constraint-based allocation solvers, secure protocol infrastructure, high-throughput blockchain indexing, and performant, well-documented APIs.**

You'll work on systems where correctness, reliability, performance, and security directly affect user funds and protocol integrity. The role has significant ownership and autonomy across offchain infrastructure and components that interact closely with smart contracts and onchain state.

You will also work closely with Quant Engineers. Quant owns the financial models, assumptions, validation, and calibration. Backend owns the production systems, data pipelines, and services that run those models. Smart contract engineers own their onchain integration and enforcement.
