Top Cyber Security Jobs

Deliver post-sales advisory and hands-on implementation for application security and performance. Gather requirements, produce designs (HLD/LLD), build and migrate solutions, configure Cloudflare products, troubleshoot escalations, collaborate with support and engineering, and create operational assets, documentation, scripts, and automation to enable customer adoption and smooth transitions.

Design, build, and operate secure, resilient distributed systems for secrets and key management across Cloudflare's global network. Re-architect and strengthen internal PKI and machine/workload identity, support and run services (including on-call), and consult with teams to ensure secure system design and usage.

Provide advanced technical support and advisory to enterprise customers on network security and performance (OSI layers 3,4,7). Troubleshoot DDoS, BGP, GRE, SSL/TLS, firewall/WAF, and hosting issues; perform packet analysis; create docs and KB articles; collaborate with engineering; and use automation and generative AI to accelerate incident response.

Design, build, and operate high-throughput, low-latency authentication and authorization services. Evolve IAM systems to distributed, edge-capable architectures; define robust APIs; ensure reliability, observability, and security; conduct reviews and design docs; and use AI-assisted tools to accelerate development while owning production reliability.

Respond to security incidents across on‑premises, cloud, and hybrid environments. Perform active edge mitigation (WAF rules, L3/L4 shunning), full incident response lifecycle (investigation, containment, remediation, recovery), and coordinate with customers and internal teams to detect, isolate, and remediate sophisticated attacks.

Build automated GRC solutions and maintain the GRC platform; architect AI governance for autonomous agents; support audit readiness (SOC 2, ISO 27001, PCI, FedRAMP) via automated drift detection and self-healing; and integrate security across Legal, People, Engineering, and Finance to enable developer-friendly compliance.

Conduct vulnerability scanning and in-depth analysis, triage and prioritize findings, produce remediation guidance, track remediation progress, and ensure processes and evidence meet DoD IL4 and FedRAMP compliance requirements while collaborating with engineering and compliance teams.

Conduct AI security research, agentic and LLM testing, vulnerability discovery, adversary simulations, and full-chain red team operations. Test WAF, EDR, and SIEM detection efficacy using MITRE ATT&CK, collaborate with blue teams and incident response, develop detection validation frameworks, report risks to executives, and mentor security professionals.

Lead product security assessments, threat model features, triage and own vulnerability lifecycle from bug bounty, SAST, fuzzing, and pentests. Build AI/LLM-driven automation and tooling to scale triage and enrichment, mentor engineers, and influence security across distributed cloud products.

Conduct threat models and security reviews for Cloudflare products, triage and manage vulnerability lifecycle (bug bounties, SAST, fuzzing, pentests), build AI/LLM-driven automation tooling for triage and enrichment, coordinate pentests and remediation with engineering, and act as the product security point of contact.
