movement and behavior, and recognize events and the people involved.
This role focuses on the practical engineering work that makes it all possible — sourcing,
processing, and versioning training data across multiple formats and sources, developing internal
tools that ML engineers rely on daily, and contributing to a complete ML platform for automated
training, evaluation, and deployment.

What we're looking for

Must have:
• CS fundamentals — familiarity with common data structures and algorithms
• Python skills — ability to write clean, maintainable code
• Database fundamentals — understanding of different database types, core concepts like
indexing, schemas, transactions, and SQL queries
• Basic understanding of computer vision concepts
• Experience working with common data formats — JSON, XML, YAML

Good to have:
• Experience with object detection frameworks
• Familiarity with OpenCV, NumPy, Pandas, or similar data processing libraries
• Exposure to MLOps tooling — experiment tracking, dataset versioning, data pipelines

We offer:
• An opportunity to take on new challenges, advance your career, and make a meaningful impact.
• Opportunity to be part of a fast-paced and dynamic environment that encourages creativity, critical thinking, and the exploration of new ideas.
