[Hiring] Mobile Engineer (iOS) @OnHires

Role Description

As an iOS Software Engineer, you will own the iOS client experience end-to-end. This is not a thin integration role — you will build a production-grade iOS application where AI interactions are central to the product. Performance, reliability, and user trust will be your top priorities.

• Build and maintain iOS applications using Swift and SwiftUI.
• Integrate AI-powered features through backend APIs.
• Design UX patterns for AI interactions (loading states, streaming responses, retries, 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.

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.

Expected Outcomes

• Stable, smooth, and reliable iOS applications for real-world use.
• Optimized performance: responsive, low-latency, efficient on memory and CPU.
• Production issues detected early, monitored effectively, and resolved with clear root-cause analysis.

Tech Stack

• Swift
• SwiftUI
• Swift Package Manager (SPM)
• SQL / NoSQL
• TensorFlow Lite (on-device inference)

Interview Process

• 3–4 interviews maximum.
• Conducted virtually and/or onsite.
• Applications evaluated directly by technical team members.
• Transparent and efficient process with prompt decisions.
• Successful candidates will receive not just a job offer, but an invitation to join a mission-driven team bringing AI to billions globally.
