iOS Developer – AI Apps

BJAK
United Kingdom · Full-time · Entry

A1 is a self-funded AI group, operating in full stealth. We’re building a new global consumer AI application where iOS is a core platform, not an afterthought.

This is a founding iOS role. You’ll design AI-powered mobile systems that balance UX excellence with the realities of AI latency, streaming, and failure modes.

Why This Role Matters

  • You define how AI feels in users’ hands
  • You bridge backend intelligence with human interaction
  • You help establish iOS engineering standards from zero
  • You influence product direction through what’s possible on-device

What You’ll Do

  • Build and maintain iOS apps using Swift / SwiftUI
  • Integrate AI-powered features via backend APIs
  • Implement camera, microphone, and media pipelines
  • Design UX for AI interactions (loading, streaming, retries, fallbacks)
  • Optimize performance, memory, and battery usage
  • Capture user feedback and signals for AI evaluation
  • Collaborate with backend and AI teams on API design
  • Maintain high App Store quality and production stability

What It’s Like to Work Here

  • You own features end-to-end
  • You design systems, not just screens
  • You think deeply about latency, reliability, and UX tradeoffs
  • You move fast, test in production, and iterate
  • You work closely with senior engineers and founders

Requirements

  • 3+ years of iOS development experience (Swift)
  • Hands-on experience integrating AI features
  • Strong understanding of async/await and background tasks
  • Experience with camera, audio, and local storage
  • Solid iOS performance and memory optimization skills
  • Experience shipping production apps

Nice to Have

  • Exposure to CoreML or on-device ML
  • Built AI chat, voice, or streaming-based apps
  • Experience with feature flags or remote config
  • Strong intuition for AI UX patterns

Our Team & Culture

We operate as a dense, senior, high-performance team. We value clarity, speed, craftsmanship, and relentless ownership. We behave like founders — we build, ship, iterate, and hold ourselves to a high technical bar.

If you value excellence, enjoy building real systems, and want to be part of a small team creating something globally impactful, you’ll thrive here.
