- Familiarity with version control (Git), CI/CD pipelines, and collaborative software development practices.
- Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.
Data Analysis:
- Experience designing and leading data-driven investigations, and visualizing results, to communicate actionable findings.
- Confidence in navigating large datasets of unique, unstructured data and preparing it for analysis, and using statistical methods to find needles in the haystack.
Domain Knowledge:
- Familiarity with the online threat landscape ranging from social media, to underground forums to ransomware/DLS ecosystems.
