Principal iOS Engineer

#### How you can make an impact:

• Own and evolve the technical architecture of Aave App on iOS, setting direction that supports rapid product development without compromising security or maintainability

• Design and ship core blockchain functionality, including wallet creation and connectivity, key management, transaction construction and signing, gas estimation, RPC interaction, onchain reads, and account-abstraction flows

• Lead the integration of onchain and offchain data across savings, funding, withdrawal, bridge, vault, portfolio, notification, and analytics experiences.

• Set standards for application architecture, Swift and UIKit code quality, testing, observability, performance, release safety, and incident response

• Remain hands-on in the codebase, particularly for foundational architecture, security-sensitive functionality, complex integrations, and critical production issues

• Partner closely with design to deliver precise UI, refined interactions, accessibility, and a cohesive mobile design system

• Coach and mentor iOS engineers, delegate meaningful ownership, provide clear technical and performance feedback, and contribute to hiring and team development
