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 Principal Backend Engineer to lead the engineering team behind Push, Aave Labs' regulated, non-custodial on-ramp and off-ramp.
This is a hands-on technical leadership role spanning the systems that connect banking and open-banking partners, identity and compliance controls, payment processing, blockchain settlement, customer wallets, and the applications through which customers access Push.
You'll set the technical direction for a high-stakes financial product where correctness, security, auditability, and operational resilience directly affect customer funds and regulatory obligations. Alongside designing and building critical systems, you'll provide day-to-day leadership to the engineering team, create clarity from product and regulatory requirements, and ensure the team can deliver safely at pace.
How you can make an impact:
- Own the technical direction and architecture for Push across backend services, external integrations, data flows, and onchain settlement
- Translate product, regulatory, and operational requirements into a clear engineering roadmap, well-scoped projects, and sound technical decisions
- Design and build resilient services for on-ramp and off-ramp transaction lifecycles, including payment initiation, status tracking, settlement, exception handling, and customer notifications
- Lead integrations with open-banking, payments, identity, compliance, and blockchain infrastructure providers
- Define secure boundaries between fiat systems, non-custodial wallets, and onchain execution, ensuring sensitive data, permissions, and signing-related flows are handled appropriately
- Set and uphold standards for secure development, architecture review, testing, observability, incident response, deployment, and sustainable on-call ownership
- Partner closely with Product, Compliance, Legal, Security, Operations, Finance, and application engineers
Remain hands-on in the codebase, particularly for complex architecture, high-risk changes, and critical production issues
Let's connect if you have:
- 8+ years of backend engineering experience, including senior technical leadership of production systems and teams
- Experience designing distributed, event-driven systems that move or account for real money, with a strong understanding of failure modes and operational risk
- Experience with regulated financial products and understanding how to balance compliance and regulatory requirements with product features and goals
- Strong backend programming skills. Production experience with Rust is highly desirable; deep experience with Go, Java, C++ can substitute
- Strong knowledge of API design, PostgreSQL or another relational database, messaging systems, and service-to-service integration patterns
- Experience in regulated fintech, payments, banking, digital assets, or another environment requiring auditability, controls, and high availability
- Excellent system-design judgement, including migration strategy, build-versus-buy decisions, security boundaries, and the long-term operational cost of architecture choices
- A track record of leading engineers through ambiguous, high-impact work while remaining close to implementation and production operations
