About the role

Our threat detection platform analyzes 500 million network events per day for mid-size enterprises. Traditional SIEM rules catch the obvious stuff. Our ML models catch the rest — lateral movement patterns, anomalous authentication sequences, and data exfiltration attempts that look normal individually but form a pattern over time. You'll build and refine the ML models behind our detection engine. That means feature engineering from raw network logs, training anomaly detection and classification models, tuning alert thresholds to balance detection rate against analyst fatigue, and continuously adapting to new attack patterns. Cybersecurity ML has a unique challenge: the adversary is actively trying to evade your models. If you find that cat-and-mouse dynamic intellectually stimulating, and you have the ML skills to back it up, this is a role where you'll never be bored.

Fully remote.
