We want someone who will help us amplify the positive and inclusive team culture we’ve been building.

Key job responsibilities

• Design, build, and deploy AI/ML systems that process threat data at scale, running over petabyte-scale security logs with real-time inference
• Conduct thorough data analyses and develop prototypes for detecting otherwise-unknown security problems
• Independently frame ambiguous problems, and then define and deliver a research agenda with limited guidance
• Seek out, develop, and advocate for new technologies to solve scientifically-complex security problems
• Build consensus on scientific approaches, balancing analytic rigor with the operational urgency inherent to security
• Mentor and develop teammates both technically and professionally
• Publish patents and peer-reviewed articles, and present your research both internally and externally
