Data/AI Engineer (IoT sphere)

Bulgaria

Company Background

The customer offers access solutions and products around the world. Their innovative offerings and partnerships, supported by a smart ecosystem, empower their clients with cutting-edge access solutions, ensuring safe traversal across homes, garages, community spaces, commercial areas, and storage units.

Project Description

The project focuses on strengthening the AI foundation, enhancing validation scripts, and resolving inconsistencies in object detection models across various hardware platforms. Key efforts include improving validation tools for Gen AI-based models, particularly for smart search and descriptive notifications, updating accuracy metrics for people and face detection, and developing automation for model testing on target devices. In parallel, the team will refine the data curation process by shifting attention from traditional object detection to Gen AI needs, emphasizing the curation and annotation of customer-submitted videos. These initiatives aim to ensure consistent model performance and more intelligent, context-aware AI capabilities.
