These facilities were also recognized as Sustainability Lighthouses for breakthroughs in efficient operations. With our global reach, we ensure the global supply chain has access to the Flash memory it needs to keep our world moving forward.

Job Description

We’re hiring a Senior Manager of Operational Technology (OT) to lead Sandisk’s OT visibility and resilience program across high‑technology manufacturing sites. You’ll stand up and mature our OT monitoring solution, integrate telemetry into our SIEM, and partner with factory operations to ensure security without disrupting production.

This role owns strategy, delivery, and ongoing operations of OT security—bridging engineering, manufacturing, and the SOC—so that Sandisk maintains continuous production with zero downtime due to internal cybersecurity incidents.

ESSENTIAL DUTIES AND RESPONSIBILITIES
  • Program Leadership: Define and execute the OT security roadmap, aligning with corporate cybersecurity strategy and manufacturing uptime objectives.
  • OT Monitoring Deployment: Oversee installation and configuration of OT monitoring platforms such as Nozomi Networks, Claroty, Dragos, Armis, ensuring proper sensor placement for maximum visibility.
  • Traffic Analysis & Protocol Coverage: Implement tools for deep packet inspection and protocol analysis (e.g., Wireshark, Zeek, Suricata) to monitor Modbus, Profinet, DNP3, OPC‑UA, and other industrial protocols.
  • SIEM Integration: Collaborate with SOC and architecture teams to stream OT telemetry into SIEM/SOAR platforms, develop detection logic, and optimize alerting to reduce false positives.
  • Asset & Risk Management: Establish and maintain a comprehensive OT asset inventory, vulnerability management process, and configuration baselines for critical systems.
  • Network Segmentation & Access Control: Drive segmentation projects, firewall rule reviews, and identity separation between IT and OT environments; implement secure remote vendor access protocols.
  • Incident Response & Resilience: Develop OT-specific incident response playbooks, conduct tabletop exercises, and ensure disaster recovery plans meet manufacturing continuity requirements.
  • Compliance & Standards: Ensure adherence to NIST CSF, IEC 62443, and corporate security policies; prepare for internal and external audits.
  • Cross-Functional Collaboration: Work closely with onsite IT teams and Manufacturing leadership to schedule changes, minimize production impact, and jointly achieve zero-downtime objectives.
  • Metrics & Reporting: Define KPIs (e.g., telemetry coverage, MTTR, segmentation compliance) and deliver executive-level reporting on OT security posture.
Qualifications
Required
  • Experience: Minimum 10 years in OT/ICS security, industrial control systems, or manufacturing network engineering, with at least 5 years in a leadership role.
  • High-Tech Manufacturing Expertise: Proven experience in semiconductor or advanced electronics manufacturing environments, understanding production constraints and uptime requirements.
  • Technical Expertise: Deep knowledge of OT protocols (Modbus, Profinet, DNP3, OPC‑UA), PLC/SCADA systems, and sensor deployment strategies.
  • Security Tools: Hands‑on experience with OT monitoring platforms (Nozomi, Claroty, Dragos, Armis) and integration with SIEM/SOAR solutions.
  • Network Skills: Proficiency in configuring SPAN/RSPAN/ERSPAN, packet capture, and traffic analysis using tools like Wireshark or Zeek.
  • Risk & Compliance: Familiarity with NIST CSF, IEC 62443, and MITRE ATT&CK for ICs frameworks; experience conducting risk assessments and implementing compensating controls for legacy systems.
Skills
  • Leadership & Communication: Proven ability to lead cross‑functional teams, manage vendors, and communicate effectively with technical and executive stakeholders.
Preferred
  • Credential segregation between IT and OT domains; knowledge of OT vulnerability management tools.
