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.
You'll own a broad technical area with high ownership and turn ambiguous product goals into reliable production systems. Correctness, security, and operability are critical: the services you build will support customer transactions, sensitive account flows, and financial data across both onchain and offchain infrastructure.
How you can make an impact:
- Design, build, and operate backend services for Aave App across onboarding, funding, savings, withdrawals, portfolio data, and customer communications
- Build transaction-orchestration and indexing services that safely prepare, submit, monitor, and reconcile onchain activity across its full lifecycle
- Integrate with smart contracts, RPC providers, account infrastructure, payment partners, and other external services, designing for degraded dependencies and partial failure
- Lead technical reviews for high-value systems and improve testing, observability, alerting, incident response, and deployment practices across the backend codebase
- Work closely with mobile, web, product, design, protocol, security, data, and operations teams to deliver coherent consumer experiences
- Raise the engineering standard through hands-on delivery, pragmatic architecture, clear documentation, and review that helps other engineers grow
Let's connect if you have:
- 6+ years of backend engineering experience, including ownership of complex production systems
- Strong backend programming skills. Production experience with Rust is highly desirable, but we'll also consider strong systems experience in Go, C++, Java.
- Experience building distributed, event-driven, or data-intensive systems with clear reliability and performance requirements
- Strong knowledge of API/GraphQL design, PostgreSQL or another relational database, caching, queues, and observability
- Experience with blockchain systems, particularly transaction signing, private-key or key-management flows, wallet infrastructure, and onchain transaction lifecycles, is highly desirable.
- Strong judgement around threat modelling, sensitive data, permissions, and the operational risks of systems handling financial value
Nice to haves:
- Experience with EVM-compatible networks, smart accounts, account abstraction, bridges, or DeFi protocols
- Experience building consumer fintech, savings, wallet, exchange, or payments products at meaningful scale
- Experience with cross-chain indexing, large-scale data ingestion, Kafka, ClickHouse, or similar infrastructure
