Job Description

Lab Summary:

Bixby is an intelligent personal assistant which is only available as a built-in application on Samsung flagship devices and wearables. This application uses Natural Language Understanding to perform tasks on these devices using voice/ text, including but not limited to making phone calls, sending text messages, setting up meetings, opening apps, setting alarms and timers, getting directions, answering general questions, providing information about restaurants and other businesses, etc.

Samsung Bixby Labs is working towards a vision of a voice assistant that provides a unified AI experience across multiple devices. Our industry-leading hardware platforms like the Galaxy phones, and home appliances like smart refrigerators and TVs, smart washers and dryers, etc. allow for deep integration of the AI services like Bixby voice assistant and hardware devices. Real-time AI services on these connected IoT devices enable users to interact with devices more naturally via spoken dialogue, visual interaction, continuous learning, and big data analysis. Researchers and engineers are working hard towards making the Samsung vision a reality.

Position Summary:

Modern AI services are delivered online, in real-time and 24x7. To adapt to this new world, we are building a continuously monitoring and updating platform centered around AI and machine-learned models. The platform manages model training, multiple production releases, data analytics, integration, bugs, rollbacks, patches, A/B testing, online monitoring, etc. The processes are independent of the type of real-time AI service – voice assistants, web search, autonomous vision systems, etc. If you are interested in data science, AI and machine learning platforms for the online AI services world, this is your dream job.
