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
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.
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
- 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
