Vacant job

We are looking for a Data Scientist who wants to explore the unknown with us and build products that make a real difference in society.

Find insights where others see noise

What happens when you combine advanced machine learning with some of society's most complex data flows? At Xolaris, we explore the answer every day. We work in environments where data is incomplete, uncertain, and difficult to interpret – where standard methods are insufficient and the ability to detect hidden patterns is crucial. Our clients operate in areas where confidentiality, precision, and insight play a central role: civil and military intelligence, law enforcement, security, and defense.

As a Data Scientist, you will have the chance to shape how we tackle problems that no one else has solved before. You will be part of an experienced team, working cross-functionally, where you will engage in the entire development chain: from exploration and analysis to prototypes and finished solutions.

We combine advanced data analysis, machine learning, deep learning, generative methods, and representations of complex information to uncover patterns that would otherwise remain hidden. You will work with techniques such as Generative AI, Deep Learning, LLMs, Vector Embeddings, and NER, as well as tools like Python, PyTorch, Spark, LangChain, and Jupyter.

In this role, you are expected to:

• Explore, analyze, and model complex, uncertain, and often incomplete data.
• Develop prototypes and solutions that work both in theory and real-world usage.
• Identify patterns and relationships where traditional methods fall short.
• Work closely with domain experts and technicians in cross-functional teams.
• Contribute to a high level of sensitive information management and security-conscious practices.

We are looking for someone who:

• Is driven by challenges and solving difficult problems that no one has solved before.
• Is curious, analytical, and motivated to create solutions that make a difference in society.
• Has experience in data science, machine learning, or related fields.
• Thrives in an environment where quality, security, and responsibility are natural parts of everyday life.
• Can undergo a security clearance if necessary.

What we offer

We offer competitive terms, occupational pension, modern equipment, free training, and wellness grants. Competence development is a natural part of our work – we learn from each other, test new methods, and invest in training that strengthens both you and the organization. We prefer to work together on-site in the office to promote problem-solving and mutual understanding, but remote work is possible when needed.
