Oracle
Security Engineer 4
Job Description
What you’ll do (key responsibilities)
Security research & threat modeling
Investigate emerging TTPs, business-logic abuse patterns, and identity/OAuth attack paths.
Build and maintain adversary playbooks mapped to MITRE ATT&CK; drive coverage roadmaps.
Detection engineering (detection-as-code)
Ship high-quality detections using Sigma/KQL/SPL/OSQuery/eBPF, versioned as code with CI/CD.
Instrument cloud/SaaS telemetry pipelines; reduce noise via tuning, suppression, and risk scoring.
AI-assisted analytics
Apply ML for anomaly detection, clustering, and outlier triage; prototype LLM/RAG assistants for playbook generation, enrichment, and hypothesis-driven hunts.
Partner with data teams to productionize models with feedback loops (precision/recall tracked).
Threat intelligence integration
Build ingestion/enrichment pipelines (TIPs, OSINT, ISACs, vendor feeds); normalize IOCs/TTPs.
Correlate TI with detections & hunts; drive proactive hardening and hypothesis creation.
Proactive controls & response acceleration
Recommend/implement preventive controls (authz hardening, rate limits, token binding, WAF rules).
Automate response (SOAR/runbooks), shrinking MTTD/MTTR with measurable impact.
Metrics & continuous improvement
Own coverage and efficacy KPIs (FPR/FNR, time-to-detect, time-to-close, alert fatigue).
Run post-incident detection reviews and continuously up-level our catalog.
Minimum qualifications5–8+ years in security engineering/detection engineering/threat research for cloud/SaaS.
Applied AI/ML experience for security (feature engineering, anomaly detection, basic model evaluation).
Strong detection content skills (Sigma/KQL/SPL/OSQuery/eBPF) and detection-as-code practices (Git, tests, CI/CD).
Demonstrated threat hunting experience (hypothesis-led, telemetry-driven) at scale.
Hands-on with SIEM/SOAR and cloud-native telemetry (e.g., AWS/GCP/Azure, Kubernetes, API logs).
Solid programming for automation/data wrangling (Python/Go) and comfort with SQL.
Working knowledge of MITRE ATT&CK, adversary emulation, and identity-centric threats (SSO/OIDC/OAuth).
Preferred qualificationsBuilt TI pipelines/TIP integrations; mapping intel → detections/hunts/playbooks.
Experience tuning detections to reduce false positives without losing recall; risk-based alerting.
