Team & Leadership Impact (Build Championship Teams)

• Partner closely with engineering, platform, SRE, and SOC teams to drive observability, enforce best practices, and continuously strengthen edge defense posture across globally distributed environments.
• Collaborate with traffic engineering, observability, and infrastructure teams to ensure scalable, fault-tolerant configurations across multi-CDN environments.
• Contribute to continuous improvement of runbooks, dashboards, and operational standards for the Perimeter Security Operations Center (PSOC), raising the operational baseline for the broader team.

Fan & Customer Impact (Obsessed with Fans)

• Protect the availability and integrity of the platforms that serve millions of fans daily by leading incident response and mitigation efforts for perimeter-layer attacks, including scraping, credential stuffing, carding, and API abuse.
• Manage DNS, networking, and delivery routing systems — including global traffic managers, failover policies, and load-balancing configurations — to ensure fans experience fast, reliable, and secure access across all channels.
• Perform ongoing signature tuning, rule deployment, and traffic analysis to improve signal-to-noise ratios across WAF and CDN layers, reducing friction for legitimate fan traffic while blocking threats.
• Develop and implement executive-level traffic report briefings using automation, AI, and machine learning tooling to ensure actionability and strategic insight that directly supports fan-first decision-making.

Innovation & Problem Solving (Limitless Entrepreneurial Spirit)

• Develop AI and agentic skillsets, workflows, and processes — including Claude skills, MCP integrations, and LLM-assisted triage — that scale PSOC operations, with validation of AI outputs against ground truth to ensure reliability.
• Design and implement automation workflows in SOAR platforms (e.g., Tines, Torq, N8N) to streamline operations, enhance incident response, and reduce manual toil across the security stack.
• Operate, maintain, and optimize the perimeter defense stack across edge and origin layers, including Akamai, Cloudflare, Blink Ops, Imperva, Fastly, Impart, and AWS WAF, identifying opportunities to improve efficacy and performance.
• Design, implement, and enforce guardrails for AI and agentic systems — including bounded action scopes, approval gates, audit logging, and kill switches — to ensure automated production changes remain safe and auditable.

Ownership & Execution (Determined & Relentless Mindset)

• Monitor, analyze, and respond to security events in partnership with Perimeter Security analysts and threat detection teams, maintaining a high standard of response quality and speed.
• Develop automation and tooling to support alerting, ticket creation, and configuration validation using Splunk, Tines, and Jira, driving operational consistency and reducing response times.
• Participate in a global on-call rotation for perimeter-related incidents and operational escalations, demonstrating reliability and accountability in high-stakes situations.
• Apply anomaly detection, bot management, and operational traffic analysis to identify and mitigate emerging threats, continuously improving the edge defense posture of one of the world's largest sports commerce platforms.
