Android Developer – AI Apps
BjakA1 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
