Principal Product Security Architect

The Principal Product Security Architect is a senior technical leadership role responsible for the research, design, prototyping, and operationalization of advanced security solutions delivered through Lumen’s Managed and Professional Security Services portfolio. This role bridges Product Development, R&D, Engineering, and Security Operations, ensuring that security architectures are scalable, automated, operationally viable, and aligned with Lumen Validated Designs (LVD). 

The architect will drive innovation enabling differentiated, market‑ready cybersecurity offerings that support end‑to‑end lifecycle delivery (Day 0 design, Day 1 implementation, Day 2 SOC operations). 

• Lead research and development (R&D) of new and emerging security technologies to be brought to market under Lumen Managed and Professional Services.
• Define evaluation plans, success criteria, and validation frameworks for assessing security platforms, tools, and integrated solutions.
• Architect, design, and lead the development of prototype and proof‑of‑concept solutions, transitioning validated designs into production‑ready offerings.
• Partner closely with Security Operations (SOC) and Product Management teams to ensure architectures are operationally sound, automatable, and support 24/7 delivery models.
• Collaborate across Product Management, Engineering, Operations, Sales Engineering, Legal and Service Assurance to align technical design with product strategy and customer requirements.
• Evaluate, design, and implement security automation and orchestration capabilities for SecOps, including SOAR‑driven workflows and AI‑assisted operations.
• Develop and maintain architecture documentation, reference designs, runbooks, and operational guides 

• Design architectures that explicitly account for multitenant, shared infrastructure, cloud and customer owned environments.
• Design solutions that prioritize alert quality, analyst efficiency, and measurable SOC outcomes, including false positive reduction and meantime to respond improvements.
• Ensure all architectures include Day 2 operational metrics, instrumentation, and feedback loops.
• Deliver technical enablement and training for internal teams, including SOC analysts, engineers, and solution architects.
• Engage with third‑party security technology providers across Lumen’s connected ecosystem to architect joint managed solutions.
• Support end‑to‑end security solution delivery, from initial architecture through implementation and steady‑state SOC operations (Day 0 / Day 1 / Day 2).
• Work with stakeholders to understand interface requirements and operational needs included AI compliance, Security, and Risk Management
• Ensure designs are consumable by Public Sector customers, where appropriate, including systems requiring Authority To Operate (ATO) 

Experience across a broad set of security technologies, including but not limited to: 

• MDR / XDR
• Managed SIEM (cloud & on prem)
• SOAR and playbooks
• Next‑Generation Firewalls (NGFW)
• Vulnerability Scanning and Management
• CASB
• SASE
• Quantum‑related security concepts (e.g., QKE)
• AI‑driven security analytics and automation
• Security of AI (model protection, data integrity, adversarial resilience)
• AI for Security (threat detection, response automation, predictive analytics)
• Threat intelligence integration and operationalization (internal and thirdparty feeds)
• Identity Cenric architectures
