What you will do

• Shape the defense strategy by translating vague security threats into concrete mathematical problems and championing a rapid prototyping culture.
• Lead the evolution of threat detection by introducing more advanced probabilistic modeling, graph analytics, supervised and unsupervised learning.
• Act as a force multiplier, mentoring junior scientists and engineers, and building internal tooling, feature stores, and libraries.
• Prioritize engineering rigor (CI/CD, scalable code) and adversarial resilience to deliver production-grade models that the SOC actually trusts.

Requirements

• Extensive experience (3-5+ years) in data science, with at least 2+ years dedicated to the cybersecurity domain.
• Practical knowledge of security frameworks such as MITRE ATT&CK and OCSF.
• Hands-on comfort with high-volume logs and proficiency with Spark/Pyspark, Snowflake, Flink, and streaming services such as Apache Kafka.
• Deep understanding of containerization (Docker) and workflow orchestration (Kubernetes, Apache Airflow) for automated ML pipelines.
• Mastery of Python programming, including proficiency in leading ML frameworks (TensorFlow, PyTorch).
• Demonstrated success in implementing comprehensive MLOps methodologies, encompassing CI/CD pipelines, testing protocols, and model performance monitoring.

Nice to have

• Masters or PhD in a quantitative field.
• Expertise in advanced Natural Language Processing (NLP) methodologies.
• Experience contributing to open-source security data science tools.
• Background in offensive security (Penetration Testing/Red Teaming) with an "attacker's mindset."

Culture & Benefits
