Network Security Engineer

W2 Only Job Description: Must-Haves / Core Skillset: Micro-Segmentation and Zero Trust:Hands-on experience with workload-level segmentation and lateral-movement prevention.Demonstrated ability to move from visibility to enforcement safely in production environments.Illumio or Equivalent Platform Experience:Strong understanding of VEN agents, SaaS policy engines, enforcement modes, and migration considerations.Comfort working directly with vendor engineering teams during live operational issues.Traffic and Telemetry Analysis:Strong proficiency with SIEM tools (especially time-based analysis, distributions, and baselining).Ability to reason about event ingestion pipelines and end-to-end telemetry delivery.Operating Systems and Infrastructure:Solid Linux and Windows server fundamentals.Understanding of application communication patterns, service dependencies, and network flows.Operational Maturity:Experience with production change management and incident response.Ability to halt or delay enforcement when telemetry or validation is insufficient.Communication and Influence:Ability to clearly communicate technical risk, impact, and recommendations to engineers, leadership, and vendors.Comfortable translating telemetry and failures into executive-level summaries.Mission (Overarching Goal):Advance the enterprise Zero Trust micro-segmentation program, delivering safe, auditable, and scalable traffic visibility and policy enforcement across hybrid environments (on-prem and cloud). This role ensures operational reliability, policy confidence, and vendor accountability for Illumio SaaS–based segmentation at enterprise scale.Day-to-Day Responsibilities:Operate and mature the Illumio micro-segmentation platform (SaaS with limited on-prem presence), including VEN agent lifecycle management across Windows, Linux, and future AIX workloads.Design, validate, and deploy least-privilege segmentation policies, ensuring policy changes can be safely verified via traffic telemetry before and after enforcement.Analyze traffic flow telemetry and delay metrics across ingestion pipelines and SIEM tooling to validate platform health, identify regressions, and distinguish policy issues from platform or vendor constraints.Lead incident response and vendor escalation with Illumio engineering, including capacity constraints, SaaS scaling events, maintenance windows, and potential data integrity risks.Partner with Network Engineering, NOC/NMC, application teams, and platform owners to coordinate production changes, policy deployments, and change-management activities.Maintain and evolve security standards, baselines, and deployment guidance for enterprise micro-segmentation, aligning to internal governance, audit, and risk requirements.Support large-scale onboarding and migration efforts, including SaaS cutovers, phased policy enforcement, and certification of segmentation controls for high-risk and payment applications.Nice-to-Haves (Certifications / Extras): Security and Architecture:CISSP, CCSP, or comparable security architecture certificationZero Trust–focused training or vendor micro-segmentation certificationsCloud and Identity:Familiarity with Azure and enterprise IAM concepts (SaaS authentication, RBAC, API access)Advanced Platform Integration:Experience integrating segmentation telemetry into SIEM, data lakes, or automation pipelinesExposure to policy certification, audit traceability, or regulatory reporting. Additional Skills:Micro-SegmentationNetwork Macro-SegmentationIn this contingent resource assignment, candidate may:Consult on or participate in moderately complex initiatives and deliverables within Information Security Engineering and contribute to large-scale planning related to Information Security Engineering deliverables.Review and analyze moderately complex Information Security Engineering challenges that require an in-depth evaluation of variable factors.Contribute to the resolution of moderately complex issues and consult with others to meet Information Security Engineering deliverables while leveraging solid understanding of the function, policies, procedures, and compliance requirements.Collaborate with client personnel in Information Security Engineering.Required Qualifications:4 plus years of Information Security Engineering experience, or equivalent demonstrated through one or a combination of the following: work or consulting experience, training, military experience, education.
