Job Description Visa’s Cyber Security team is seeking a Cloud Security Architecture with an automation-first mindset to design, build, and operate large‑scale, cloud‑native and AI‑driven security platforms that protect Visa’s global brand, networks, products, and data. This role combines hands‑on engineering, automation‑first security design, and technical leadership in a highly dynamic, high‑impact environment. The ideal candidate is a strong cloud security engineer and problem solver with deep experience in Python‑based services, cloud security engineering, API‑driven architectures, and automation, and who is excited to apply GenAI and autonomous agent technologies to modern security challenges. This role plays a critical part in reducing time-to-onboard-workload, time‑to‑detect (TTD) and time‑to‑remediate (TTR) by driving intelligent automation, threat intelligence enrichment, and policy‑as‑code across Visa’s multi‑cloud ecosystem. Key Responsibilities Security Engineering & Platform Development Design, develop, and operate large‑scale cyber security platforms that deliver detection, prevention, and response capabilities across cloud and hybrid environments. Build cloud‑native, API‑first security services using Python and modern web service frameworks. Develop and expand security integration frameworks to interconnect SIEM, CSPM, CNAPP, IAM, network security, and threat intelligence platforms. Drive security automation to minimize manual intervention and accelerate incident response workflows. GenAI & Agentic Security Capabilities Design and implement GenAI‑powered security workflows, including: Autonomous agents for cloud misconfiguration analysis, policy validation, and remediation recommendations AI‑assisted threat triage, alert summarization, and root‑cause analysis Intelligent enrichment of security signals using applied threat intelligence Build and operate agentic systems that can reason across telemetry, policies, and infrastructure state to propose or execute remediation actions safely. Evaluate and adopt emerging LLM, agent orchestration, and AI governance frameworks for enterprise‑grade security use cases. Ensure secure, compliant, and auditable use of GenAI, including data handling, prompt safety, access controls, and model risk considerations. Cloud Security & Automation Engineer and enforce cloud security controls across Azure (or AWS) in large‑scale enterprise environments. Implement Infrastructure‑as‑Code (IaC) and automation frameworks to provision and manage security controls using tools such as Terraform. Drive Policy‑as‑Code and Guardrails, authoring and maintaining policies using: Integrate GitOps‑based promotion pipelines (dev → test → prod) with secure remote state management and drift detection. Threat Detection, Response & Posture Management Reduce time‑to‑detect and time‑to‑remediate by automating: Threat intelligence ingestion and correlation Sensor enrichment and contextual risk scoring Design and operate cloud security posture management (CSPM/CNAPP) capabilities using platforms such as Wiz, Prisma Cloud, or Microsoft Defender for Cloud. Work across multiple security domains including: Cloud firewalls and security groups, DDoS protection, Network proxies, Cloud‑native SIEM platforms (e.g., ADX, Sumo Logic) Architecture, Innovation & Leadership Lead technical design discussions and translate business requirements into secure, scalable architectures. Conduct proof‑of‑concepts (POCs) for new technologies, tools, and architectures, evaluate feasibility and drive production adoption. Stay current with emerging cloud, security, and AI technologies, proactively assessing their applicability within Visa. Act as a technical leader and mentor, raising the engineering and security maturity of the team. Contribute to project planning, including cost estimation, timelines, and risk assessment for new security initiatives.
