Staff Security Engineer - Security Data, Detection and Automation
NscaleNscale is the Hyperscaler engineered for AI.
Role Description We are hiring a Senior Staff Engineer - Security Data, Detection and Automation to build the telemetry, detection, response automation, case-quality metrics, and reporting foundation for an increasingly Nscale-owned SOC capability. This role sits at the intersection of security engineering, data engineering, detection engineering, and security operations. You will work across endpoint, identity, SaaS, cloud, network, vulnerability, and production access domains, partnering closely with security leadership as well as adjacent teams shaping identity and vulnerability management requirements. Your impact will be strategic and measurable. The focus is not to create more alerts, but to turn raw telemetry into reliable, explainable, high-signal security outcomes that strengthen internal ownership of detection logic, containment decisions, runbooks, executive metrics, case quality, and automation. What you'll be doing - Security Telemetry and Data Foundations - Design security telemetry architecture across various domains. - Build a telemetry source map covering ownership, data quality, retention, coverage, priority use cases, and known gaps. - Establish data quality, parser quality, ingestion health, field normalization, and source ownership standards. - Create daily source-health reporting and scoring for SIEM or security analytics data quality. - Detection Engineering and Threat Coverage - Own the detection engineering lifecycle from hypothesis and data source selection through logic, testing, tuning, ownership, runbook, expiry, and metrics. - Define high-value detection use cases across various domains. - Develop detections with documented test logic, runbooks, data dependencies, and case-quality criteria. - Apply TTP-led threat modeling across various risk scenarios. - Validate detection coverage through attack simulation or other coverage-testing approaches. - Automation and Operational Improvement - Build SOAR and automation workflows that enrich alerts, suppress low-value noise, route cases, and improve analyst decision-making. - Design scalable data pipelines, enrichment flows, and automations that improve operational quality. - Implement detection-as-code or version-controlled detection content where practical. - Use automation to improve the consistency, explainability, and actionability of security outcomes. - SOC Performance and Reporting - Measure MDR/SOC performance using case-quality metrics. - Create a MDR/SOC case-quality review loop for internal and external stakeholders. - Produce security dashboards and executive reporting that connect security operations to measurable risk reduction. - Improve alert explainability for analysts and leaders. - Cross-Functional Partnership - Partner with security leadership to strengthen internal ownership of detection logic, containment decisions, runbooks, executive metrics, and automation. - Collaborate with Identity and Vulnerability Management hires to define detection requirements. - Connect engineering and operational stakeholders around shared standards. Qualifications - 8+ years in detection engineering, security data engineering, SIEM engineering, security automation, incident response engineering, or similar roles. - Strong hands-on experience with SIEM, security analytics, log management, or detection platforms. - Strong ability in coding, scripting, querying, or detection-content development. - Experience building detection logic from various telemetry sources. - Experience with detection testing, threat hunting, incident response, alert tuning, and runbook development. - Ability to design scalable data pipelines, enrichment flows, or automations. - Strong understanding of attacker TTPs, MITRE ATT&CK, identity attacks, cloud attacks, endpoint telemetry, and insider-threat indicators. - Experience with SOAR, case management, detection-as-code, GitOps, CI/CD, or automated detection testing is preferred. - Experience measuring MDR, SOC, or managed detection provider performance is preferred. - Experience using AI or agentic workflows to improve triage, enrichment, investigation, or detection validation with guardrails is preferred. Benefits - Highly competitive US compensation package (base + bonus + equity), with performance reviews every 12 months. - Join one of the fastest-growing AI infrastructure companies. - Expect a dynamic progression plan tailored to your ambitions. - Human-First Flexibility: A flexible workplace that trusts Nscalers to deliver.
