Miratech is hiring a Network Security Architect

We are looking for a Network Security Architect to lead the security architecture for a large-scale network consolidation program at a US-based Tier-2 Telco. The role owns security design, firewall rule consolidation, and policy definition, focusing on transforming fragmented legacy security postures into a standardized target-state architecture executable at scale. This position is ideal for professionals experienced in large-scale firewall transformations who excel at simplifying complex rule sets and designing scalable, segmented security architectures. Responsibilities Translate enterprise-level security architecture into actionable, site-level security blueprints aligned with the overall program vision. Define and document the target-state architecture for the Network Security domain, including firewall rule consolidation, VRF-based macro-segmentation, and DDoS mitigation strategies. Analyze and optimize legacy security policies by consolidating overlapping firewall rules into streamlined, standardized templates. Collaborate closely with client Security and CISO teams, supporting design validation, risk alignment, and compliance with regulatory frameworks (e.g., CISA, HIPAA). Identify and resolve complex IP subnet overlaps and security-related routing conflicts flagged during data analysis phases. Define clear security exit criteria and guardrails as part of the migration factory Definition of Done (DoD). Contribute to architecture governance, including participation in architecture reviews, design approvals, and development of enterprise standards and reference architectures, while collaborating with cross-domain architects.
