Has Bjak posted this job before?
Yes. We’ve followed 5 other AI Phone - On-device AI / ML Systems Engineer jobs there since November 2026. All 5 are still up.
Large employers often post one title for several teams, so these can be separate openings.
Demand for ML Engineer roles
New ML Engineer postings at the employers we follow are up 12% over the last 5 weeks compared with the 5 before.
Each bar is one week of new postings. The darkest bars are the last 5 weeks.
Counted from the hiring pages we’ve followed for at least five weeks, so employers we add don’t look like growth. Updated weekly.
About the role
We file this job under ML Engineer, by the work the posting describes.
ML engineers put machine learning models into products. They write the code that trains, ships, serves and monitors models so a recommendation or prediction works for real users.
Postings ask for strong Python and software engineering, a framework such as PyTorch, cloud services, and more and more often experience with large language models.
A data scientist often works out which model to build; an ML engineer makes it run reliably in production.

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.
