About The Position

Wells Fargo is seeking a Cyber Defense Principal Engineer to serve as a senior technical leader responsible for designing, advancing, and operationalizing enterprise‑wide detection, response, and threat‑mitigation capabilities. In this role, you will Engineer and optimize enterprise detection and response platforms (SIEM, SOAR, EDR, NDR, cloud‑native tools) to improve coverage, resilience, and time‑to‑detect/respond. Develop high‑quality detections leveraging threat models, behavior analytics, MITRE ATT&CK, and intelligence‑driven TTPs—balancing fidelity with operational efficiency. Build automated response playbooks and investigation tooling to streamline SOC/IR workflows and reduce MTTD/MTTR. Strengthen telemetry pipelines (onboarding, normalization, enrichment, schema governance, retention) for critical systems, identity providers, and cloud services. Operationalize threat intelligence by translating IOCs/TTPs into actionable detections and mitigations; prioritize emerging risks. Serve as a technical escalation point during major incidents, guiding log analysis, forensics, containment, and recovery efforts. Partner closely with Cloud, Infrastructure, IAM, DevSecOps, and Application Security to embed controls and ensure defense‑in‑depth across the stack. Lead evaluations and POCs of new technologies; drive continuous improvement of risk‑based metrics and reporting. Mentor engineers and contribute to engineering standards, runbooks, and best practices.
