Job description

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.
