OT Security Engineer

Reference: rn7i7zqcizoqmycsytv0

We are seeking an experienced OT Security Engineer to help protect operational technology environments that support essential industrial processes. This role will contribute to the design, implementation and continuous improvement of security controls across industrial control systems, supervisory control and data acquisition (SCADA) platforms, distributed control systems and associated network infrastructure.

You will assess cyber security risks across operational environments, identify vulnerabilities and support the development of practical remediation plans. Working closely with engineering, infrastructure, operations and information security teams, you will ensure that security measures are effective without compromising safety, reliability or production requirements.

Key responsibilities will include monitoring OT networks and systems for suspicious activity, supporting incident investigation and response, maintaining asset and network inventories, and contributing to security assessments, audits and compliance activities. You will also help develop and maintain policies, standards, procedures and documentation covering access control, secure configuration, patching, vulnerability management, remote access and network segmentation.

The successful candidate will have practical experience in OT, industrial cyber security or a closely related engineering environment. You should understand common industrial protocols and technologies, such as Modbus, DNP3, OPC and Ethernet/IP, together with the principles of segmentation, firewalls, intrusion detection and secure remote connectivity. Familiarity with recognised frameworks and standards, including IEC 62443, NIST Cybersecurity Framework and ISO 27001, would be advantageous.

Strong analytical and problem-solving skills are essential, along with the ability to communicate technical risks clearly to both specialist and non-specialist audiences. Relevant qualifications in cyber security, computer science, engineering or a related discipline are desirable. Experience of working in safety-critical, regulated or highly available environments would be beneficial.

This is an opportunity to play a key role in strengthening the resilience of critical operational systems while supporting a positive, collaborative and security-conscious culture.
