Job LocationCINCINNATI GENERAL OFFICESJob DescriptionAt P&G, we believe that diverse experiences help build strong leaders. Mobility is a key component of many management careers, providing opportunities to grow through different assignments, locations, and business challenges. Candidates should be prepared to consider relocation opportunities throughout their career as business needs and development opportunities arise. The Senior Detection Engineer plays a vital role in InfoSec's Cyber Defense Technology team, responsible for building, tuning, and scaling detection capabilities across enterprise SIEM platforms. This role operates at the intersection of detection engineering and AI — using agentic AI tooling and LLM-assisted workflows to accelerate threat detection development, validation, and coverage analysis.You will work within a threat-informed detection pipeline where intelligence drives what we detect, and AI agents assist in rule creation, validation, and optimization. The role is hands-on: writing detection logic, managing detection-as-code via git, collaborating with Threat Intelligence and Threat Hunting teams, and continuously improving alert fidelity.Key Success MetricsYour success would be based on operational and project deliverables, which would be reviewed on a quarterly basis. Your manager would provide full-support though continuous mentoring and coachingDetection rules you write catch real threats and generate minimal noiseYou measurably improve alert fidelity (TP rate) and reduce SOC case volumeYou operate independently within the detection-as-code workflow (branch → validate → deploy)You leverage AI tooling to work faster — not as a research project, but as a daily force multiplierQuarterly deliverables reviewed with your manager through continuous mentoring and coachingJob Responsibilities: Detection Engineering:Design, build, test, and tune detection rules mapped to MITRE ATT&CK, prioritized by threat intelligence and business riskWrite detection logic across the SIEM and data lake platformsManage detection content as code — Git-based workflows, PR reviews, CI/CD deployment pipelinesInvestigate and suppress false positives systematically using lookup-based architecturesCollaborate with Threat Hunting and Threat Intelligence teams through structured handover processes (TI→TH→DE pipeline)Monitor emerging threats and rapidly develop detections for new TTPs, CVEs, and active campaignsAI-Augmented Detection (Differentiator):Leverage AI agents and LLM-assisted workflows to accelerate detection rule development, validation, and coverage analysisUse and contribute to MCP (Model Context Protocol) tooling that enables AI-assisted detection validation (e.g., querying telemetry, assessing LOLBAS/GTFOBins, checking coverage gaps)Operate agentic pipelines that triage large rule libraries against live telemetry at scaleApply AI/ML techniques where appropriate for anomaly detection, behavioral analytics, or pattern identification in security datasetsStay current on frontier AI threats (agentic attacks, LLM-assisted exploitation, AI-generated phishing) and translate them into detection opportunitiesCollaboration & Operations:Work closely with SOC analysts to understand alert quality feedback and drive fidelity improvementsCollaborate with data engineers on telemetry availability, data quality, and log source onboardingContribute to detection coverage reporting and MITRE ATT&CK posture measurementDocument detection logic, tuning rationale, and suppression decisions Job QualificationsTechnical Competencies and Experience:Required:Bachelor’s degree in Information Systems, Information Technology (IT), Computer Science, Engineering, or other technical / IT field and / or at least 5+ years of relevant experience in detection engineering, security operations, or threat detection rolesProven experience writing and tuning SIEM detection rules/analytics (correlation rules, scheduled queries, real-time alerts)Strong understanding of MITRE ATT&CK framework and its application to detection coverageProficiency in Python for automation, scripting, and toolingExperience with git-based workflows (branching, PRs, CI/CD) for managing security contentFamiliarity with security log sources: EDR, identity, cloud, network, proxyStrong analytical skills and ability to distinguish true threats from noise in large datasetsPreferred:Certifications CISSP, CCSP, OSCP, GIAC Certified Detection Analyst (GCDA), GCIA, Relevant certifications in cloud & ML/AIExperience with multiple query languages are helpful but not requiredExperience with detection-as-code practices and YAML-based rule formats (Sigma, custom schemas)Working knowledge of AI/LLM capabilities and their security implications — both as detection targets and as engineering toolsExperience with MCP servers, GitHub Copilot, or other AI-assisted development workflowsFamiliarity with SOAR platforms and their integration with detection pipelinesUnderstanding of Kubernetes, cloud-native architectures, and OT/ICS environmentsCompensation for roles at P&G varies depending on a wide array of non-discriminatory factors including but not limited to the specific office location, role, degree/credentials, relevant skill set, and level of relevant experience.
