Design UX patterns for AI interactions, including streaming responses, retries, and partial results.
Optimize performance, memory usage, and responsiveness for AI-heavy flows.
Implement analytics, logging, and feedback capture to support AI evaluation and iteration.
Collaborate closely with backend and ML engineers on API contracts and system behavior.
Ensure app stability, security, and scalability in production environments.
Ideal Experiences
3+ years of Android development experience using Kotlin.
Hands-on experience integrating AI features (e.g. LLM, vision, speech APIs).
Strong understanding of asynchronous programming (Coroutines, Flow).
Familiarity with REST or gRPC APIs and structured data formats.
Strong debugging and performance profiling skills.
Comfort building in environments with latency, partial failure, and non-deterministic behavior.
Experience with MLKit or light on-device inference.
