Job Title: Senior Network Security Engineer (Microsegmentation)Designation: Technical Architect

Location: Bangalore

Job Summary: We are seeking a highly skilled Senior Network Security Engineer with a strong focus on microsegmentation and Zero Trust principles. The ideal candidate will be responsible for translating high-level business objectives into comprehensive network security solutions, ensuring the security and resilience of our global IT infrastructure. This role requires a deep understanding of network security architecture, microsegmentation strategies, and cross-team collaboration to enhance our security posture.

Responsibilities:

• Translate high-level business strategic objectives into Enterprise IT requirements and conceptual designs.
• Develop and support comprehensive solutions that align with Clients's global network security and microsegmentation strategy.
• 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.
• 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 for 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 the adoption of microsegmentation platforms (e.g., Guardicore/Akamai Segmentation).
• Develop segmentation governance models, policy lifecycle management, and compliance alignment (CIS/NIST/Zero Trust frameworks).
• Participate in network security design reviews to 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.

Mandatory Skills:

• Strong hands-on experience in designing and implementing microsegmentation solutions in complex enterprise environments.
• Proven capability to build application-aware segmentation policies based on traffic flow analysis.
• Experience with policy simulation, enforcement, monitoring, and optimization in segmentation platforms.
• Understanding of east-west traffic inspection, workload protection, and software-defined segmentation.
• Familiarity with Zero Trust Network Access (ZTNA) and identity-driven access models.
• Strong experience managing LAN/WAN security technologies, including firewalls, IDS/IPS, SIEM, VPN, and NAC.
• Expertise in firewall architecture and design with hands-on experience in Fortinet, Palo Alto, and Juniper.
• Experience securing public and private cloud environments (AWS, Azure, GCP).
• Strong knowledge of routing protocols, network services, and IPv4/IPv6 architecture.

Preferred Skills:

• Experience with Web Application and API Protection (WAAP) solutions.
• Experience with SDN and SD-WAN architectures, including segmentation use cases.
• Experience managing enterprise data center environments with technologies including Aruba, Arista, and Juniper switching.

Qualifications:

• Bachelor's Degree in Computer Science, Network Engineering, or related field (or equivalent experience).
• Preferred certifications: CCNP / CCIE, JNCIE Security certifications (CISSP, CISM, or equivalent).
