Senior Detection Engineer

Position Overview

We are seeking an experienced Threat Detection Engineer to extend Vectra's detection capabilities in partnership with Data Scientists and Security Researchers who are developing our AI-driven Attack Signal.

Vectra's Attack Signal Production Group is responsible for building Vectra's core threat detection and prioritization technology, leveraging AI and other methods to alert customers to critical threats in their network and cloud environments. Threat Detection Engineers work closely with Data Scientists who are developing AI models, and Security Researchers who are researching the threat landscape and assisting modeling efforts. Detection Engineers focused on Network attack behaviors complement Vectra's coverage by building Suricata signatures, specifying detection logic in python, and utilizing other available methods.

Responsibilities and Accountabilities:

• Analyze network traffic to identify and document threat patterns.
• Develop and maintain network-based security signatures in Suricata.
• Use offensive security tools and techniques to simulate attacks and generate sample network traffic.
• Collaborate with data scientists and security researchers to support detection efforts and improve detection accuracy.
• Continuously monitor and assess the effectiveness of network detections, making adjustments as needed.
• Contribute to threat hunting efforts by identifying new tactics, techniques, and procedures (TTPs) used by attackers.
• Participate in incident response activities as required.

Attitudes and Behaviors:

• Focus on impact and results; work on the right things and get them done
• Drive and resourcefulness to persevere and overcome obstacles achieving challenging goals
• Track record of successfully solving complex and ambiguous problems
• High integrity and ability to positively collaborate with others

• Expertise in writing signatures with Suricata
• Excellent people, technical and communication skills, and the ability to work collaboratively in a team environment.
• Advanced knowledge of common operating systems, services, networking protocols, logging, cloud and SaaS environments
• Knowledge of attacker techniques and tools (e.g., Metasploit, Cobalt Strike), and prior operational experience leveraging threat intelligence to detect and respond to adversaries
• Familiarity with data utilized by detection technology, for example PCAPs, flow logs, cloud logs, etc.
• Proficiency with related languages and frameworks, e.g. bash, python, Sigma, YARA-L, Linux/Unix, Wireshark, etc.
• Scripting, software development, engineering, and/or devops experience; experience with a source control system, preferably Git
• Optional certifications - OSCP, GCIA, GCDA, GSEC
