Senior Quantitative Researcher

Petra Security is building an AI-driven Detection and Response platform to stop account compromise and other cyberattacks. The Senior Quantitative Researcher will own core machine learning detection research, design and deploy real-time account-compromise models, take models from research to production, architect systems for scale, and raise the technical quality of the team.

Responsibilities:

• Build and evolve our detection models. Working closely with our CTO and Head of Machine Learning, you'll design and build the ML models that identify account compromise in real time
• Take models from research to production. You don't just care about model performance in a notebook. You're energized by measuring how your models behave at scale in a live system with real attackers
• Architect for scale. We're growing fast. Nothing excites you more than architecting and implementing an elegant solution that'll handle 10-100x the scale in 6 months
• Raise the technical bar. As a senior voice on a lean team, your instincts and opinions shape how we build. You'll establish patterns, push for correctness, and raise the quality of everything around you
