Android Developer – AI Apps

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.

• 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

• 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

• 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

• 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

• 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

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.

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.
