Android Developer – AI Apps
Join to apply for the Android Developer – AI Apps role at BJAK. A1 is a self-funded AI group, operating in full stealth. We’re building a new global consumer AI application focused on an underexplored use case. Android is a core surface of this product – not a wrapper.
What It’s About
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
