Senior Network Security Engineer (Microsegmentation)

Key Responsibilities

- Translate high-level business strategic objectives and goals into Enterprise IT requirements and conceptual designs.
- Develop and support comprehensive solutions that meet requirements and align with HPE’s global network security and microsegmentation strategy.
- Develop and maintain a multi-year strategic network and security architecture roadmap, incorporating Zero Trust and segmentation-driven security models.
- Lead end-to-end network and security architecture across global platforms ensuring secure, high-performing, fault-tolerant, and resilient environments.

Microsegmentation & Zero Trust Responsibilities

- Architect and implement microsegmentation strategies across data center, campus, and cloud environments to limit lateral movement and enforce least-privilege access.
- Design and operationalize Zero Trust Architecture (ZTA) principles, integrating identity, application, and network-based policy enforcement.
- Collaborate with application owners to discover, validate, and map application dependencies to enable policy-driven segmentation.
- Define and enforce granular security policies using label/tag-based segmentation approaches across hybrid environments.
- Integrate microsegmentation with firewalls, SIEM, IAM, EDR/XDR, and cloud-native controls for unified policy enforcement.
- Lead adoption of microsegmentation platforms (e.g, Guardicore/Akamai Segmentation).
- Develop segmentation governance models, policy lifecycle management, and compliance alignment (CIS/NIST/Zero Trust frameworks).

Core Network Security Responsibilities

- Participate in network security design reviews and ensure all implementations meet enterprise security standards.
- Analyze business requirements to design and implement security across data centers, campus networks, and hybrid environments.
- Provide ongoing risk metrics, control effectiveness tracking, and security posture reporting.




- Conduct and support internal and external security audits and compliance assessments.
- Maintain awareness of emerging threats and update policies accordingly.
- Develop and manage policies, processes, and procedures ensuring reliability, availability, and security of network systems.
- Manage and optimize Security Information and Event Management (SIEM) systems.
- Collaborate with Cyber Security, infrastructure, and application teams toward compliance and operational excellence.

- Strong understanding of structured cabling and network facilities.

Operations & Lifecycle Management

- Plan, implement, and document infrastructure changes, including upgrades and migrations.
- Work within ITIL frameworks for incident, change, and problem management.

Education & Certifications

- Bachelor’s Degree in Computer Science, Network Engineering, or related field (or equivalent experience).
- 10+ years of experience in global network security environments.
- Preferred certifications:
- CCNP / CCIE
- JNCIE
- Security certifications (CISSP, CISM, or equivalent) are a plus

Key Differentiators Added (for your context)

This version strengthens the JD by:

- Embedding microsegmentation as a core capability (not just one bullet)
- Aligning with Zero Trust and application dependency mapping (important for your programs)
- Emphasizing cross-team collaboration with application owners (critical for rollout success)
- Integrating segmentation with existing firewall + SIEM ecosystem (not replacing, but complementing)
