A1 is a self-funded AI group, operating in full stealth. We’re building a new global consumer AI application focused on an important but underexplored use case. Android is a core surface of this product - not a wrapper.

This is a founding mobile role. You will design and build Android systems that connect real-world inputs (camera, audio, files) to powerful AI backends, while delivering smooth, resilient user experiences under real-world constraints like latency, failures, and offline states.

Why This Role Matters
  • You define how users experience AI — not just how it works

  • Your decisions shape performance, reliability, and UX at scale

  • You solve hard problems at the boundary between device, network, and AI systems

  • You build production systems, not demos

  • You help set mobile engineering standards from day one

What You’ll Do
  • Build and maintain production Android apps using Kotlin

  • Integrate AI features (chat, vision, voice, recommendations) via backend APIs

  • Implement camera, microphone, file uploads, and background processing

  • Design UX patterns for AI interactions: streaming, retries, partial results

  • Optimize performance, memory, and responsiveness for AI-heavy flows

  • Implement analytics, logging, and feedback capture for AI evaluation

  • Collaborate closely with backend and AI engineers on API contracts

  • Ensure app stability, security, and scalability in production

What It’s Like to Work Here
  • You own features end-to-end

  • You design for failure, latency, and uncertainty by default

  • You move fast, but with engineering discipline

  • You work directly with backend and AI builders

  • You treat mobile as a first-class system, not a thin client

Requirements
  • 3+ years of Android development experience (Kotlin)

  • Hands-on experience integrating AI features (LLM, vision, STT/TTS APIs)

  • Strong understanding of async programming (Coroutines, Flow)

  • Experience with camera, audio, and offline/local storage

  • Familiarity with REST/gRPC APIs and structured data formats

  • Strong debugging and performance profiling skills

Nice to Have
  • Experience with MLKit or light on-device inference

  • Built AI chat, agent-based, or AI-powered consumer apps

  • Understanding of AI limitations (latency, hallucinations, failures)

  • Experience working closely with AI or data teams

  • Published production apps on the Play Store

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.

About A1

A1 is a self-funded, independent AI group, focused on building a new consumer AI product with global impact. We’re assembling a small, elite team of ML and engineering builders who want to work on meaningful, high-impact problems.
