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.

  • 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
