Job summary

Pivot Search is seeking an experienced iOS Developer to own the iOS client experience for an AI-powered chat app. You will build production-grade iOS applications where AI interactions are central to product experience, and performance, reliability, and user trust are critical.

You will ship features in Swift/SwiftUI, integrate AI via backend APIs, optimize for latency and energy use, and collaborate with backend/ML engineers to shape API design and system behavior.

Qualifications

• 3+ years of iOS development experience using Swift.
• Hands-on experience integrating AI-powered features into mobile apps.
• Strong understanding of async/await, concurrency, and background tasks.
• Solid iOS performance and memory optimization skills.
• Experience shipping and maintaining production iOS apps.
• Comfort designing for latency, partial failure, and non-deterministic AI behavior.
• Exposure to CoreML or light on-device ML.
• Familiarity with feature flags or remote configuration systems.
• Strong intuition for AI UX patterns and user trust considerations.

Responsibilities

• Build and maintain iOS applications using Swift and SwiftUI.
• Integrate AI-powered features through backend APIs.
• Design UX patterns for AI interactions, including loading states, streaming responses, retries, and fallbacks.
• Optimize performance, memory usage, and battery efficiency.
• Capture user signals and feedback to support AI evaluation and iteration.
• Collaborate closely with backend and ML engineers on API design and system behavior.
• Maintain high App Store quality, stability, and production reliability.

Job description

Our Clie is building a proactive AI chat app for everyday users to bring intelligence to conversations, errands, organising and workflows. Unlike traditional chat-based applications, our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior.

About the Role

As an iOS Developer, you own the iOS client experience, how AI feels, responds, and performs in users’ hands. This is not a thin integration role.
