About Bjak

Bjak 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.

Job Summary

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.

Key Responsibilities

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

Requirements

3+ years of Android development experience (Kotlin)
Hands-on experience integrating AI features (LLM, vision, STT/TTS APIs)
Strong understanding of async programming and performance optimization

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
