• Lead incident response efforts related to segmentation, and coordinate with vendor engineering teams during escalations
• Partner with network, infrastructure, and application teams to plan and execute production changes safely
• Develop and maintain security standards, baselines, and governance frameworks aligned to compliance requirements
• Support onboarding, migration, and rollout efforts for segmentation across critical and high-risk applications
• Translate technical findings into clear insights for both engineering teams and executive stakeholders
  
  

Minimum Qualifications

• Bachelor's degree or equivalent practical experience
• 4 years of experience in Information Security Engineering or related field
• Experience with network security concepts, including firewalls, routing, and segmentation
• Hands-on experience with Linux and/or Windows server environments
• Experience with SIEM tools and telemetry analysis
• Strong communication skills with the ability to explain technical concepts to varied audiences
  
  

Preferred Qualifications

• Experience with micro-segmentation and Zero Trust architectures
• Hands-on experience with Illumio or a similar segmentation platform
• Experience implementing workload-level segmentation and preventing lateral movement
• Familiarity with traffic analysis, baselining, and event pipeline troubleshooting
• Experience in incident response and production change management
• Knowledge of cloud environments (e.g., Azure) and identity/access management concepts
• Experience integrating security telemetry into SIEM, data platforms, or automation pipelines
• Relevant certifications (e.g., CISSP, CCSP, or Zero Trust/micro-segmentation certifications)
  
  

Key Skills

• Micro-segmentation & Zero Trust architecture
• Network security and traffic flow analysis
• SIEM tools and telemetry pipelines
• Illumio or equivalent platforms (VEN agents, SaaS policy engines)
• Python (basic to intermediate)
• API testing (Postman)
• ServiceNow, JIRA, Confluence
• Server and networking fundamentals
  
  

What Success Looks Like

• Reliable and scalable deployment of segmentation policies across hybrid environments
