We're looking for a Junior Python Developer to join our AI team, where you'll help teach our video

devices to see more than just a picture — to distinguish specific objects in the frame, track their

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
  
  
  

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
