Data Scientist

Have you ever worked in the hardware company that develops laser-based consumer product from the growth of semiconductors crystals to the final applications developed by IT and data science teams? Sounds interesting? Let’s talk!

Brolis Sensor Technology is leading the way in transforming the dairy farm industry with our groundbreaking technology. Introducing Brolis HerdLine, an innovative milk analyzer developed by our hardware engineers, data science and IT teams in Lithuania and Belgium. Product utilizes Mid-IR tunable laser technology and has the potential to dramatically improve dairy farms management regarding animals nutrition, breeding, health, and impact on the environment realizing sustainable and efficient dairy farming.  We take pride in being a company that focuses on delivering high-quality software and hardware solutions that directly cater to the needs of our valued end users.

More about the product:

Our solution for milk composition analysis uses the latest data engineering technologies and machine learning models to provide accurate real-time insights into the quality and composition of milk to dairy farms. By extensively collecting data from sensors, we are able to generate a comprehensive picture of the milk’s characteristics.

We are seeking an experienced Data Scientist to join our data science team. In this role, you will be responsible for developing machine learning models to provide insights regarding animals health and productivity by combining real-time milk composition with animal-related information from our clients’ farms and third party data.
