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
