Full job description

About We are reimagining the phone. AI phones need to be proactive, intuitive, intelligent and low cost. This is a mission critical for rest of the world to adopt intelligence. There are over 5 billion people using everyday applications such as email, messaging, notes, tasks, and calendars, yet most are not AI-native. Our mission is to build proactive applications and devices that bring intelligence into daily conversations, coordination and workflows, with minimal prompting.

Responsibilities

  • Evaluate suitable open-weight and commercially available models for on-device execution.

  • Benchmark model performance on target mobile hardware.

  • Integrate models into Android applications and system services.

  • Optimize inference latency, memory consumption and power usage.

  • Evaluate quantization, compression and model distillation techniques.

  • Work with CPU, GPU and NPU acceleration.

  • Evaluate local model capabilities for different workflows.

  • Build hybrid local/cloud model routing mechanisms.

  • Identify which tasks can be handled locally and which require cloud inference.

  • Work with AI agent engineers to integrate local models into the agent runtime.

Requirements

  • Strong ML systems or inference engineering experience.

  • Experience deploying and optimizing models.

  • Strong Python and C++ skills.

  • Understanding of neural network inference.

  • Experience with model quantization and performance optimization.

  • Understanding of hardware constraints and inference benchmarks.

Nice to have

  • Experience with on-device LLMs.

  • Qualcomm QNN, MediaTek NeuroPilot or similar acceleration frameworks.

  • ONNX Runtime, LiteRT, TensorFlow Lite or ExecuTorch.

  • Android NDK.

  • Mobile or edge AI deployment.

  • Multimodal model optimization.
