Mid/Senior Data Scientist

Job Description

Our Data Science team, working across Surfshark and Incogni products, is looking for a skilled Data Scientist. Our projects cover a broad spectrum of data science challenges, from time series modeling to traditional NLP and generative AI. We follow a value-driven approach and are deeply committed to the growth and success of our products. If you're enthusiastic about cybersecurity, data protection, and data science, we'd love to see your application.

• Design, develop, and deploy machine learning solutions for real-world problems, including classification, entity matching, and extraction, as well as LLM-powered text analysis;
• Write clean, efficient, and testable Python code for data pipelines, feature engineering, modeling, and evaluation;
• Own models end to end: problem framing, data exploration, model selection, validation, deployment, and iteration;
• Work closely with product and engineering teams to turn ambiguous problems into concrete, data-driven solutions;
• Explore, evaluate, and apply modern ML approaches, from established algorithms to state-of-the-art techniques, balancing model performance, complexity, and real-world impact;
• Communicate findings clearly to both technical and non-technical stakeholders, focusing on decisions, trade-offs, and outcomes to drive informed business decisions.

Requirements

• Proven experience in applied machine learning, with a track record of independently owning and delivering ML projects from problem definition to validated results or production
• Strong NLP background, including hands-on experience with text classification, embeddings, and LLM-based systems
• Advanced Python skills, with the ability to write clean, efficient, and maintainable code
• Solid SQL skills and experience working with large, imperfect, real-world datasets
• Strong understanding of machine learning fundamentals, model evaluation, and common failure modes
• Ability to translate ambiguous business problems into practical ML solutions, make informed technical decisions, and communicate results and trade-offs clearly
• Experience with collaborative development practices, including version control, code reviews, testing, and reproducible experimentation
• Comfort with AI-assisted coding tools to improve development efficiency, while maintaining high standards for code quality, correctness, and maintainability
