Provide technical support to large, sophisticated customers to detect and mitigate network threats across OSI layers 3–7 using Cloudflare products (Magic Transit, WAF, Network Firewall, Spectrum). Troubleshoot networking (BGP, GRE), perform packet analysis, advise on filtering and rate limiting, collaborate with engineering to resolve attacks, and communicate with customers via chat, email, and phone.

Develop and maintain FPGA-based DRAM security test infrastructure and automation to validate mitigations and characterize memory behaviors. Build high-precision FPGA platforms, host software, PCIe integrations, and scalable validation pipelines. Use AI-assisted tools to accelerate development, create test frameworks, analyze large-scale results, and partner with product security and DRAM architects to define threat-informed validation strategies and roadmaps.

Senior Cloud Security Engineer responsible for hands-on remediation of cloud and infrastructure vulnerabilities, operating vulnerability and CSPM tooling, enforcing secure configurations across Azure environments, embedding security in CI/CD and IaC, supporting compliance/audits and reporting, mentoring engineers, and partnering with cross-functional teams to maintain cloud security posture and policy.

Design, implement, and operate enterprise network and access security across hybrid environments (on‑prem and multi‑cloud). Manage firewalls, ZTNA, NAC, proxies, and microsegmentation; investigate security events; automate security operations with Python/Ansible/Terraform; develop standards, documentation, and remediation; mentor junior engineers and collaborate with infrastructure, cloud, and security teams.

Lead and deliver cybersecurity projects, champion and enforce security best practices across the software organization, and serve as a subject-matter expert for at least one platform, project, or component. Support and communicate standards to engineering teams and participate in hiring/onboarding assessments and pre-employment screening as required.

Partner with engineering, compliance, and security teams to embed application security into the SDLC: triage static/SCA alerts, advise on OWASP Top 10 remediation, maintain developer playbooks and training, track security metrics and evidence for audits, and help shape AI governance and GenAI-safe workflows.

The role involves designing and managing secure cloud infrastructure on AWS, automating security practices, and collaborating with various teams to improve developer workflows and ensure compliance.
