Senior Cybersecurity Engineer

Visa Visa · Fintech · Bellevue, WA

Senior Cybersecurity Engineer at Visa focused on designing, building, and operating AI-driven security platforms. The role involves applying GenAI and autonomous agents to security challenges, including misconfiguration analysis, threat triage, and remediation. It requires strong cloud security engineering, Python development, and automation skills, with a focus on reducing detection and remediation times. The position also involves evaluating and adopting LLM and agent orchestration frameworks, ensuring secure AI usage, and leading technical design and innovation.

What you'd actually do

  1. Design, develop, and operate large‑scale cyber security platforms that deliver detection, prevention, and response capabilities across cloud and hybrid environments.
  2. Build cloud‑native, API‑first security services using Python and modern web service frameworks.
  3. Develop and expand security integration frameworks to interconnect SIEM, CSPM, CNAPP, IAM, network security, and threat intelligence platforms.
  4. Drive security automation to minimize manual intervention and accelerate incident response workflows.
  5. Design and implement GenAI‑powered security workflows, including: Autonomous agents for cloud misconfiguration analysis, policy validation, and remediation recommendations.
  6. AI‑assisted threat triage, alert summarization, and root‑cause analysis.
  7. Intelligent enrichment of security signals using applied threat intelligence.
  8. Build and operate agentic systems that can reason across telemetry, policies, and infrastructure state to propose or execute remediation actions safely.
  9. Evaluate and adopt emerging LLM, agent orchestration, and AI governance frameworks for enterprise‑grade security use cases.
  10. Ensure secure, compliant, and auditable use of GenAI, including data handling, prompt safety, access controls, and model risk considerations.
  11. Lead technical design discussions and translate business requirements into secure, scalable architectures.
  12. Conduct proof‑of‑concepts (POCs) for new technologies, tools, and architectures, evaluate feasibility and drive production adoption.
  13. Stay current with emerging cloud, security, and AI technologies, proactively assessing their applicability within Visa.
  14. Act as a technical leader and mentor, raising the engineering and security maturity of the team.
  15. Contribute to project planning, including cost estimation, timelines, and risk assessment for new security initiatives.
