Senior Information Security & OT Officer Jobs (On-site work)

Explore senior information security & OT officer jobs and discover a critical career at the intersection of digital and physical security. This senior-level role is dedicated to protecting an organization's most vital assets: its information technology (IT) systems and its operational technology (OT) environments. OT encompasses the industrial control systems (ICS), supervisory control and data acquisition (SCADA) systems, and other hardware and software that monitor and control physical processes in industries like manufacturing, energy, utilities, and transportation. Professionals in this field are the strategic guardians who ensure the resilience of both corporate data and essential industrial operations against escalating cyber threats. The core mission of a Senior Information Security & OT Officer is to develop, implement, and oversee a unified cybersecurity strategy that spans traditional IT networks and specialized OT architectures. Common responsibilities include conducting comprehensive risk assessments tailored to industrial environments, defining and enforcing security policies and procedures, and ensuring compliance with critical frameworks such as ISO 27001, NIST, and the ISA/IEC 62443 series for industrial automation and control systems security. They lead incident response planning and execution for cyber events that could impact safety and production, and they design secure architectures to segment and protect sensitive OT networks. A significant part of the role involves liaising between executive leadership, IT teams, and engineering/operations staff to communicate cyber risks and align security initiatives with business objectives. Typical skills and requirements for these senior jobs include a bachelor’s or master’s degree in computer science, information security, engineering, or a related field, coupled with substantial experience (often 5+ years) in cybersecurity, with a specific focus on OT/IACS environments. Candidates must possess a strong technical understanding of both IT security principles (firewalls, intrusion detection) and OT protocols and systems. Expertise in risk management methodologies and industrial security standards is paramount. Success in this profession demands excellent communication and collaboration skills to bridge the cultural and technical gap between corporate IT and plant floor operations, often coordinating security posture across multiple sites or regions. For those seeking to defend critical infrastructure and lead enterprise-wide security maturity, senior information security & OT officer jobs represent a challenging and high-impact career path at the forefront of modern cybersecurity.
