About the Role

We are seeking an experienced Threat Intelligence Engineer with experience with machine learning data science to join our proactive security team. This role is a critical blend of two disciplines: leveraging Threat Intelligence (TI) to understand the adversary and then applying advanced Machine Learning and engineering principles to rapidly and effectively defend our organization. The ideal candidate will transform raw threat data into actionable security measures and automated defenses significantly reducing our mean time to detect (MTTD) and mean time to respond (MTTR) to sophisticated cyber threats.

Key ResponsibilitiesThreat Intelligence Engineering (TI)

• Intelligence Collection & Analysis: Proactively research collect and analyze threat intelligence from various sources (OSINT commercial feeds dark web and internal security events) to understand the current and emerging threat landscape.
  
  
• Machine Learning and Data Science: Design implement and maintain detection use cases for the entire machine learning lifecycle (data ingestion training deployment and inference).
  
  
• Threat Actor Profiling: Develop detailed profiles of relevant threat actors their Tactics Techniques and Procedures (TTPs) using frameworks like MITRE ATT&CK and identify potential impacts to the organization.
  
  
• Actionable Intelligence Dissemination: Produce and disseminate timely relevant and actionable intelligence reports and briefings for both technical security teams and executive leadership.
  
  
• IOC/IOA Management: Engineer the ingestion enrichment correlation and contextualization of Indicators of Compromise (IOCs) and Indicators of Attack (IOAs) into security platforms.
  
  

• Automated Defense Development: Design develop and implement robust automation workflows and playbooks (SOAR) to streamline security operations tasks including incident triage alert enrichment vulnerability management and threat response actions.
  
  
• Tool Integration & Optimization: Integrate diverse security tools (e.g. SIEM EDR Cloud Security Posture Management vulnerability scanners Threat Intelligence Platforms) through APIs and scripting (primarily Python) to create seamless automated feedback loops.
  
  
• Process Improvement: Identify manual repetitive and time-consuming security processes and engineer scalable automation solutions to increase team efficiency and operational maturity.
  
  

• Incident Response Support: Provide threat context to support the Incident Response team during active security incidents.
  
  
• Cross-Functional Partnership: Collaborate with Detection Engineers Security Engineers and Software Developers to embed security and intelligence-driven practices into the CI/CD pipeline and corporate infrastructure.
  
  

Preferred Skills

• Understanding of attacker Tools Techniques and Procedures (TTPs)
• Understanding of attack components
• Experience threat hunting in a complex network
• The ability to read an attack brief or vulnerability report and contextualize the associated risk
• Experience validating vulnerability reports and providing impact analysis
• Experience performing data gathering and analysis on perceived threats; generating additional contextual data that can be operationalized
• Experience with common tools used within Security Operations
• Experience utilizing security event information in intelligence analysis
• Ability to navigate ambiguity and provide clarity to complex situations
• Ability to work autonomously with a strong sense of urgency ownership and self drive
• Ability to build partnerships and get results across many different stakeholders
• Ability to effectively communicate both verbal and written to stakeholders regarding relative risk urgency and feedback
• Highly qualified candidates will have an understanding of nation state motivations and operational capabilities
• Experience with Infrastructure-as-Code (IaC) tools like Terraform.
• Familiarity with data analysis and visualization tools for threat intelligence
• Experience with malware analysis and reverse engineering to extract actionable indicators.

Qualifications

• Experience: 4 years of hands-on experience in a Security Engineering Cyber Threat Intelligence or Security Automation role.
  
  
• Programming: Strong proficiency in at least one scripting/programming language for automation (e.g. Python).
  
  
• Security Concepts: Deep understanding of the cyber kill chain threat actor TTPs common attack vectors networking protocols and operating system internals.
  
  
• Automation Expertise: Proven experience designing and implementing SOAR playbooks and integrating security tools via APIs.
  
  
• Intelligence Tools: Experience working with commercial and open-source Threat Intelligence Platforms (TIPs) and threat feeds.

What Makes Cloudflare Special

Were not just a highly ambitious large-scale technology company. Were a highly ambitious large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014 weve equipped more than 2400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work technology already used by Cloudflares enterprise customers--at no cost.

Athenian Project: In 2017 we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free so that their constituents have access to election information and voter registration. Since the project weve provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Heres the deal - we dont store client IP addresses never ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
