Job Summary

The Principal Architect, Technology - Enterprise Security is a senior individual contributor responsible for defining and advancing the enterprise security architecture and technical standards that protect Ziply Fiber's corporate systems, employee infrastructure, and business applications, as well as the network we operate on behalf of 1M+ broadband subscribers.

This role provides architecture-level direction across corporate and network environments - including Zero Trust strategy, threat detection and response architecture, cloud and application security, and identity and access management design. Operation of the security tooling and Security Operations Center (SOC) sits with the Security Operations function, and control governance and approval sit with Governance, Risk & Compliance (GRC). This separation of duties is deliberate and keeps architecture and design distinct from the operation and assessment of controls.

The successful candidate brings deep, hands-on security architecture expertise in a broadband ISP, telecommunications, or critical-infrastructure environment, and the demonstrated ability to translate business risk into technical design and to communicate security architecture to both engineering teams and executive stakeholders.

Essential Duties and Responsibilities:

The Essential Duties and Responsibilities listed below are a range of duties performed by the employee and not intended to reflect all duties performed.

Security Architecture & Zero Trust

·Define and own Ziply's enterprise security architecture: network segmentation, Zero Trust Network Access (ZTNA) strategy, micro-segmentation, and identity-based access-control design across corporate and network environments.

·Establish the Zero Trust reference architecture and multi-year roadmap, including policy-decision and policy-enforcement point design, device-posture and conditional-access standards, and the phased migration from perimeter-based to identity-centric access.

·Architect firewall and perimeter strategy: next-generation firewall platform selection (Palo Alto, Fortinet, or equivalent), zone and trust-boundary design, rule-governance and change standards, and policy-lifecycle design.

·Define identity and access management (IAM) architecture: MFA enforcement standards, privileged access management (PAM) design, SSO and federation patterns (SAML/OIDC), directory and service-account governance, and joiner/mover/leaver control design.

·Design secure remote-access architecture: ZTNA/SASE platform strategy, VPN-replacement roadmap, split-tunnel and posture-check standards, and endpoint-security integration.

·Establish and maintain reference architectures, design patterns, and security standards that engineering and operations teams build to, evolving them as threats and technologies change.

Network Security Architecture

·Define network security architecture for Ziply's infrastructure: out-of-band (OOB) management network design, jump-host and bastion architecture, and network-device access-control standards (TACACS+/RADIUS, role-based device access).

·Define enterprise DDoS-protection architecture, including coordination with the Subscriber Edge DDoS/Arbor program and definition of enterprise-facing scrubbing, remotely triggered black-hole (RTBH), and mitigation capabilities.

·Architect DNS security: RPZ (Response Policy Zones), DNSSEC, and DNS-over-HTTPS/TLS strategy for internal and subscriber-facing resolvers, and secure DNS/DHCP/IPAM design.

·Define network monitoring and anomaly-detection architecture: NetFlow/IPFIX analysis for security use cases, IDS/IPS placement and tuning standards, TLS-inspection strategy, and integration with the SIEM.

·Establish system-hardening baselines for network and infrastructure devices (e.g., CIS Controls, DISA STIGs, USGCB) and define secure-configuration standards for routers, switches, and firewalls.

·Define segmentation and trust-zone architecture separating corporate, subscriber, management/OT, and lab environments.

Security Operations & Threat Detection Architecture

·Define SIEM architecture in partnership with Security Operations: platform strategy or optimization, log-source onboarding standards, data-retention and normalization design, and correlation and detection-rule governance standards.

·Define detection-engineering standards, including use-case development mapped to MITRE ATT&CK, alert-tuning and false-positive-reduction practices, and detection-coverage measurement.

·Define SOC tooling architecture: SOAR platform strategy, playbook-automation standards, case-management and ticketing integration, threat-intelligence integration, and escalation-workflow design.

·Define endpoint detection and response (EDR/XDR) architecture: platform strategy, deployment and policy standards, and integration with SIEM and SOC workflows.

·Define vulnerability-management architecture: authenticated and unauthenticated scanning cadence, risk-based prioritization, remediation-SLA standards, and integration with change management and asset inventory.

·Define the architecture supporting incident response, digital forensics, and log and evidence preservation, ensuring detection and telemetry coverage across corporate and network environments.

Cloud & Application Security Architecture

·Define cloud security architecture and control standards across Ziply Fiber’s cloud environments, including AWS, Azure, Google Cloud, or equivalent platforms, with emphasis on cloud-native security tooling, CSPM, secure landing-zone design, account/subscription governance, and network-topology standards.

·Define cloud identity and workload-protection architecture: least-privilege IAM, workload identity, key and secrets management (KMS/Key Vault), and CWPP, container, and Kubernetes security standards.

·Define application-security architecture standards: API security and gateway design, secrets management, certificate-lifecycle and PKI management, and secure software development lifecycle (SDLC) integration (SAST/DAST/SCA and threat modeling).

·Architect data-protection controls: data classification, encryption at rest and in transit standards, key management, tokenization and masking, and DLP architecture for sensitive subscriber and business data.

·Define infrastructure-as-code and CI/CD security standards, including policy-as-code guardrails and pre-deployment security validation.

Governance, Risk & Compliance Partnership

·Partner with GRC to translate regulatory and compliance requirements - CPNI, CALEA, FCC telecommunications security obligations, and applicable state-level requirements - into security-architecture control designs.

·Ensure architecture designs are documentable, auditable, and mapped to Ziply's compliance framework and to industry frameworks such as NIST CSF, ISO 27001, and CIS benchmarks.

·Define secure-by-design and architecture-review standards, including reference patterns and control requirements that projects must satisfy at design and review gates.

·Contribute security-architecture review input to the deployment-governance process owned by GRC, ensuring new network and system deployments meet architecture standards before production deployment.

·Maintain segregation of duties: design controls and standards without operating, grading, or approving them - operation sits with Security Operations and governance and approval sit with GRC.

AI & Emerging Technology Security Architecture

·Define the security architecture supporting the secure and responsible adoption of artificial intelligence and machine learning across the organization, in partnership with the enterprise AI governance program.

·Design controls addressing AI-specific risks - model integrity, training-data protection, and defenses against prompt injection, model evasion, and data-poisoning attacks - aligned to frameworks such as NIST AI RMF and ISO/IEC 42001.

·Define architecture for the secure use of generative AI and AI-enabled security tooling, including data-handling, logging, and egress controls.

·Evaluate emerging technologies - such as post-quantum cryptography readiness and IoT/OT convergence - and define forward-looking architecture standards to address them.

Other Duties

·Must be available to work regular business hours Pacific Standard Time.

·Must also be available to work on-call, evenings and weekends as needed.

·Performs other duties as required to support the business and evolving organization.

Required Qualifications:

·High school diploma or GED.

·Bachelor's degree in Cybersecurity, Information Technology, Computer Science, or a closely related field. Equivalent professional experience may be considered.

·10+ years of progressive experience across security architecture, information security engineering,
