Operational Technology (OT) Security Engineer

Why Join Us? Be at the forefront of securing next-generation industrial systems in one of the most innovative companies in the world. We're looking for a visionary leader who can design resilient OT/IoT architectures and drive vulnerability management strategies that protect critical operations across semiconductor, manufacturing, and advanced technology environments. About the Role This is not just another security role—it's a chance to shape the future of OT/IoT cybersecurity. You'll combine hands-on technical depth with strategic architectural vision, ensuring our industrial ecosystems remain secure, compliant, and future-ready. The OT Security Engineer is responsible for safeguarding industrial control systems (ICS), SCADA environments, and other OT assets against cyber threats. This role ensures the confidentiality, integrity, and availability of critical infrastructure systems while maintaining operational functionality. The engineer integrates cybersecurity best practices into OT environments, balancing security with operational requirements What You'll Do Security Architecture & Design

• Develop secure architectures for OT systems, including ICS, SCADA, PLCs, and HMIs.
• Conduct design and architecture reviews to ensure compliance with security standards (e.g., ISA/IEC 62443, NIST 800-82).
• Implement network segmentation, secure remote access, and least-privilege models across IT/OT boundaries.
• Drive architectural reviews and influence security strategy across the enterprise Risk Management & Compliance
• Perform risk assessments and vulnerability analysis for OT environments.
• Ensure compliance with regulatory frameworks (e.g., RMF, ISO 27001). Advanced Vulnerability Management
• Lead vulnerability assessments for PLCs, SCADA, IIoT devices, and industrial networks.
• Develop proactive remediation strategies aligned with industry frameworks and operational priorities.
• Integrate threat intelligence into architecture and vulnerability workflows. Innovation & Collaboration
• Partner with engineering, operations, and IT teams to embed security into the system lifecycle.
• Evaluate emerging technologies and tools to strengthen OT/IoT security posture.
• Work closely with facilities and lab manufacturing teams to integrate security into operational workflows.
• Provide guidance and training to lab, manufacturing team personnel on OT security best practices What We're Looking For
• Deep expertise in OT/IoT security architecture and vulnerability management.
• 7-10 years in OT/ICS cybersecurity with proven experience designing secure industrial environments.
• Strong knowledge of ICS protocols (Modbus, OPC, Ethernet/IP) and industrial control systems.
• Familiarity with ISA/IEC 62443, Purdue Model, NIST

CSF, ISO 27001.

• Hands-on experience with Armis, Dragos, Claroty, or similar platforms. Preferred Qualifications
• Experience in highly regulated environments (energy, manufacturing, pharma).
• Knowledge of threat modeling and penetration testing for OT systems.
• Familiarity with emerging technologies like IoT in industrial environments.
• Semiconductor or advanced manufacturing experience.
• Knowledge of SEMI standards (E187/E188/E191).

Certifications:

GICSP, CISSP, or equivalent.

Soft Skills:

• Strong communication skills for cross-functional collaboration.
• Ability to translate technical security concepts for non-technical stakeholders.
