We are seeking a Senior / Principal Security Researcher to join our high-caliber Security ML Team to solve complex security challenges using disruptive technologies, AI/ML algorithms, and massive datasets to design and develop groundbreaking security solutions.
Responsibilities
- Serve as the core security domain expert within a multidisciplinary team, translating complex malware behaviors and static file attributes into actionable features, labels, or heuristics—fueling AI algorithms and automated, data-driven security logic.
- Analyze raw endpoint telemetry (such as memory buffers, hook outputs, and IPC artifacts) to evaluate algorithm effectiveness and work with AI researchers to tweak or implement new models.
- Look past the 'black box' of machine learning by digging into executable formats (PE, ELF, Mach-O) and scripts to identify malicious behavior(e.g., packing, anomalous imports, obfuscation).
- Take a security hypothesis, validate it via data analysis, and build Python-based proof-of-concepts that scale into production-grade detections—spanning machine learning classifiers to AI-informed automated rule generation.
- Influence data pipeline strategies and model design by ensuring our datasets and automated logic accurately capture the ground truth of modern threat landscapes.
