Senior AI/Machine Learning Researcher (m/f/n)

As a Senior MachineAIResearcher, you take part in researching, experimenting, and creating the best models to evaluate potential incidents. Beyond that, you look for applications ofAI/MLapproaches across the entire incident lifecycle, whether signal filtering, incident summarization, or malicious activity mitigation.

About the Role

• Explore newAI/MLopportunities,leveragingyour accumulatedexpertiseto evaluatestate-of-the-artresearch and decidewhat'sworth pursuing in our domain.

• Design and run experiments on terabytes of behavioral data (on-prem and cloud),validatingideas before production on dedicated in-house GPU servers —enough computeto compete with the biggest players in the industry.

• Challenge existing solutions and decisions — driving criticaldiscussionin the team.

• Collaborate with data collection, security operations, and software development —identifyingpromising opportunities to applyAI/MLwhere it advancesreal businessgoals.

• Mentor other researchers and steer the long-term research direction, supporting technical decisions that push the boundaries of AI/MLin cybersecurity.

Essential Requirements

• Deep understanding of the mathematical and statistical principles behind modern ML/AImethods — ability to critically evaluate and adapt models.

• Experience with modern neural network architectures, especially transformers and their variants.

• Strong drive for continuous learning and staying current withstate-of-the-artresearch.

• Ability to work independently across the full research lifecycle — from literature review to experimentation to production-ready solutions.

Desirable Requirements

• University degree in Machine Learning, Data Science, Mathematics, ora relatedtechnical field.

• Basic understanding of computer and network security.

• Experience with cloud platforms — AWS preferred.
