Ideal Candidate:
Senior Network Security Architect strong enterprise networking/security architecture hands-on PQC knowledge (FIPS 203/204/205) experience assessing PQC readiness and its impact on Firewalls WAF NAC Proxy VPN/PKI and perimeter security.

Role Overview
We are looking for a Senior Network Security Architect who can design and secure large enterprise network environments across on-prem data center and multi-cloud platforms.
The most important differentiator for this role is Post-Quantum Cryptography (PQC) expertise specifically NIST FIPS 203 FIPS 204 and FIPS 205 and how PQC impacts network security technologies.
A Network Security Architect is a senior-level IT professional responsible for planning designing testing and overseeing the implementation of secure enterprise network configurations to protect an organization from cyber threats. Acting as the strategic blueprint designer this role ensures that all local area networks (LANs) wide area networks (WANs) virtual private networks (VPNs) routers firewalls and cloud integrations align with business objectives and stringent security standards.
Subject Matter expert / domain specialist related to post-quantum cryptography (NIST FIPS ) will be required to cover Firewalls Web Application Security NAC Proxy and Perimeter Mail areas within Network Security.
Strong familiarity with NIST Post-Quantum Cryptography standards (FIPS) and their applicability to network security infrastructure
Understanding of financial industry regulatory frameworks (e.g. FFIEC DORA SEC cybersecurity guidance) as they relate to cryptographic standards
Experience supporting PQC readiness assessments in regulated industries
Awareness of harvest now decrypt later threat vectors and their implications for financial data
Ability to incorporate industry-standard compliance frameworks into the RFP deliverables and final recommendations
The Network Security Architect leads the creation of robust layered defense infrastructures. They analyze existing security postures identify structural vulnerabilities perform gap analyses and design end-to-end network security solutions. They collaborate closely with project managers security engineers and executive stakeholders to translate complex business demands into highly resilient secure technical realities.

Core Responsibilities
1. Security Architecture & Strategy Design: Design and deliver comprehensive secure network frameworks using trust domain segregation Zero Trust Architecture (ZTA) and secure zoning principles. Develop technical solutions and integration strategies across LANs WANs SD-WAN MPLS data centers and multi-cloud environments. Establish baseline configurations for network infrastructure including Next-Generation Firewalls (NGFW) Intrusion Detection/Prevention Systems (IDS/IPS) and Network Access Control (NAC).
2. Risk Assessment & Vulnerability Management: Conduct routine gap analyses and security risk assessments against recognized frameworks like NIST SANS and CIS. Evaluate proposed acquisitions and software interfaces to determine how they impact the organizations overarching network security posture. Plan and oversee regular vulnerability scanning penetration testing and ethical hacking exercises.
3. Access Control & Data Protection: Define and implement secure identity federation Multi-Factor Authentication (MFA) Single Sign-On (SSO) and Public Key Infrastructure (PKI) systems. Enforce Role-Based Access Control (RBAC) to limit network access strictly by corporate necessity and specific employee roles. Architect data-in-transit encryption paths (IPsec/SSL VPNs) and Data Loss Prevention (DLP) parameters to mitigate data leakage.
4. Incident Response & Business Continuity: Design disaster recovery plans data backup strategies and conduct routine breach-of-security simulation drills. Provide escalation support during critical network intrusions or unauthorized system access. Conduct comprehensive post-event analyses to determine exact root causes and update network models to mitigate future risks.

Required Technical Skills & Knowledge
Network Technologies: Proficient in IP routing MPLS BGP SD-WAN Wireless networks and advanced data center architectures.
Security Hardware/Software: Extensive experience deploying Checkpoint Palo Alto or Cisco NGFWs SIEM monitoring platforms and Endpoint Detection and Response (EDR) solutions.
Cloud Architecture: Hands-on experience mapping secure network perimeters inside AWS Azure or Google Cloud Platform (GCP) environments.
Frameworks & Methodologies: Deep familiarity with SABSA TOGAF COBIT ITIL and DoDAF architecture frameworks.
Automation & Scripting: Capability to write code in Python or PowerShell to automate network provisioning and logging configurations.

Experience & Education Requirements
Education: Bachelors or Masters degree in Cybersecurity Computer Science Information Technology or a closely related technical discipline.
Experience: 8 years of core IT networking experience alongside 3 years specifically focused on advanced enterprise cybersecurity architecture.
