The Role

We are hiring a Senior iOS Software Engineer to own the native mobile experience for our agentic AI platform. You will lead iOS development end-to-end: architecture, UI, networking, on-device ML, and release management. You will work closely with backend and AI engineers to surface agent capabilities in a polished, performant native client, and you will help define the standards and patterns the iOS codebase grows around.

Key Responsibilities:

Architect and build the iOS application using Swift and SwiftUI, establishing patterns for UI, state management, and data flow that the team can scale

Integrate with backend AI agent services, including streaming responses, tool-call results, and multi-step workflow state

Implement push notifications (APNs), background refresh, and local persistence to support real-time agent interactions

Own the App Store release process end-to-end: builds, certificates, provisioning, TestFlight distribution, and production releases

Build and maintain networking layers that handle authenticated API calls, streaming, retries, and offline resilience

Explore and implement on-device ML capabilities, including CoreML models, NLContextualEmbedding, and audio pipelines (Whisper, TTS) where they improve the user experience

Drive code quality and testing discipline through unit tests, UI tests, and code review

Partner with product and design to deliver polished, accessible UI that meets the quality bar of a top-tier consumer app

Mentor junior engineers and raise engineering standards across the mobile codebase
