Senior Data Scientist

About This Opportunity

We are representing a confidential cybersecurity organization seeking a Senior Data Scientist to advance machine learning and AI capabilities within their threat detection platform. This is an applied data science role focused on analyzing large-scale network telemetry, developing methods to identify malicious behavior, and improving detection accuracy across their security products.

You'll work on ambiguous, high-impact problems using statistical analysis, experimentation, and machine learning. Collaborating closely with other data scientists, threat researchers, and engineers, you'll translate research into reliable product capabilities that protect organizations from cyber threats in real time.

Responsibilities

• Analyze large-scale network telemetry to identify behavioral patterns, anomalies, and signals associated with malicious activity
• Design, develop, and refine machine learning and AI-based methods that support cybersecurity products
• Develop evaluation methods appropriate for cybersecurity data, including highly imbalanced datasets, incomplete labels, rare events, and changing attacker behavior
• Conduct exploratory data analysis, feature engineering, model development, and error analysis using complex, high-volume datasets
• Research emerging machine learning and AI techniques and assess their applicability to threat detection use cases
• Establish metrics and monitoring strategies for measuring model and detector performance over time
• Communicate findings, limitations, tradeoffs, and recommendations clearly to technical stakeholders and product leaders
• Provide technical leadership and mentorship to other data scientists through code reviews, design discussions, and contributions to analytical and engineering standards
• Document methodologies, experiments, model behavior, and evaluation results
• Write clean, maintainable, and well-tested production-quality code

What We're Looking For

Required Qualifications:

• Bachelor's degree in Data Science, Computer Science, Mathematics, or another quantitative discipline, or equivalent practical experience
• 7+ years of professional experience in data science, including developing and evaluating machine learning models for real-world use cases
• Strong foundation in statistics, experimental design, machine learning, and model evaluation
• Experience working with incomplete, noisy, or highly imbalanced data; performing detailed error analysis; and identifying causes of false positives and false negatives
• Strong proficiency in Python and SQL, with experience using common data science and machine learning libraries
• Experience collaborating with software engineers to integrate data science methods into production systems
• Strong problem-solving skills, intellectual curiosity, and a track record of independently owning complex technical work
• Excellent written and verbal communication skills, including ability to explain technical findings and tradeoffs to varied audiences

Preferred Qualifications:

• Master's degree or Ph.D. in Data Science, Computer Science, Mathematics, or another quantitative discipline
• Experience applying data science or machine learning to cybersecurity, fraud detection, abuse detection, anomaly detection, or another adversarial domain
• Familiarity with network protocols, threat detection, or incident investigation
• Experience with time-series analysis, anomaly detection, clustering, graph analytics, or unsupervised and semi-supervised learning
• Experience evaluating models in domains where positive examples are rare, labels are incomplete, and underlying behavior changes over time
• Experience with generative AI, large language models, agentic systems, or other emerging AI techniques
• Familiarity with cloud platforms such as AWS or GCP
