Job Description We are seeking a highly experienced Senior Security Engineer to own, design, and continuously improve the security tooling ecosystem that underpins a modern, detection-first Security Operations Center (SOC). This role is deeply technical and hands-on, with primary responsibility for the reliability, effectiveness, and evolution of SOC platforms. This engineer will act as the L3/L4 technical authority for the security platforms utilized by the SOC—bridging engineering and operations—while also owning EDR health & hygiene, detection engineering enablement, and emerging threat assessment. The role partners closely with SOC analysts, Incident Response, Threat Intelligence, IT Infrastructure, and Architecture teams to ensure tools are resilient, trusted, and aligned to adversary behaviors.

ESSENTIAL DUTIES AND RESPONSIBILITIES:

SOC Tooling Engineering & Ownership Engineer, deploy, and maintain all core SOC platforms, including: Malware analysis and sandboxing solutions Analyst workstation environments (Windows investigation VMs) Endpoint Detection & Response (EDR/XDR) Email Security Engineering Vulnerability Scan Engineering Act as technical owner for SOC platforms, including alignment with architecture requirements, lifecycle management, upgrades, and decommissioning Ensure SOC platforms are engineered for scale, reliability, performance, and forensic integrity Partner with IT and platform teams to resolve dependency, access, and infrastructure issues impacting SOC operations EDR Engineering, Health & Hygiene Own EDR platform engineering, configuration, and operational health across the enterprise Define and enforce EDR hygiene standards (sensor coverage, policy consistency, versioning, asset attribution) Monitor EDR health metrics and proactively remediate gaps impacting detection or response efficacy Develop testing frameworks to validate EDR detections, policies, and response actions Detection Engineering Enablement Serve as a technical owner of detection engineering, enabling high-fidelity detections through better tooling, telemetry, and data quality Validate that endpoint, sandbox, and supporting tooling generate the telemetry required to support detection logic and investigations Collaborate on detection validation, tuning, and testing pipelines Translate emerging threats and attacker techniques into tooling and telemetry requirements Malware Analysis & Investigation Enablement Engineer and maintain malware detonation and analysis environments that support safe, repeatable analysis Support SOC and IR teams with tooling for static and dynamic malware analysis Improve sandbox fidelity to better represent enterprise environments and common attacker tradecraft Emerging Threat & Capability Assessment Assess new attacker techniques, malware families, and evasion tactics for detection and prevention opportunities across the enterprise Identify gaps where tooling or configurations do not adequately surface malicious behavior Evaluate new security tools and capabilities to address detection, analysis, or response gaps Provide engineering-backed recommendations grounded in operational SOC realities Automation & Reliability Automate routine SOC operations including health checks, validation, deployments, and reporting Develop scripts and tooling (PowerShell, Python, etc.) to reduce manual overhead and analyst toil Improve reliability through monitoring, alerting, and failure-mode testing of SOC platforms Documentation & Standards Author and maintain engineering documentation for SOC platforms, architectures, and configurations Define technical standards and guardrails for SOC platforms usage and integrations Support audits, tabletop exercises, and incident reviews from a tooling and telemetry perspective Qualifications Education & Experience Bachelor’s degree in Cybersecurity, Computer Science, Information Systems, or equivalent practical experience 5–10+ years of experience in security engineering, detection engineering, or advanced SOC technical roles Demonstrated experience supporting SOC operations through engineering and platform ownership Required Technical Qualifications Deep hands-on experience with EDR/XDR platforms (e.g., CrowdStrike, Defender, SentinelOne) Experience engineering SOC platforms rather than only consuming alerts (platform ownership mindset) Strong understanding of Windows internals, Linux operating systems, and server infrastructure, including endpoint and host-level telemetry, process execution, persistence mechanisms, and administrative activity across workstation and server environments Experience supporting malware analysis and sandboxing environments Familiarity with SOC workflows, detection pipelines, and incident response requirements Strong scripting and automation skills (PowerShell, Python) Solid grasp of attacker TTPs mapped to the MITRE ATT&CK framework Preferred Qualifications Experience integrating SOC platforms with SIEM, SOAR, or case management platforms Exposure to vulnerability management and scanning platforms Experience designing detection validation or purple-team style testing Relevant certifications (GIAC, GREM, GCED, GCIA, OSCP) preferred but not required Success in This Role Looks Like High confidence in SOC platform reliability, coverage, and data quality Measurable improvements in EDR health, sensor coverage, and detection fidelity Faster, higher-quality investigations enabled by well-engineered analyst tooling Reduced analyst toil through automation and platform stability SOC detection and response capabilities that evolve in step with emerging threats Additional Information Sandisk is committed to providing equal opportunities to all applicants and employees and will not discriminate against any applicant or
