OT and Industrial Control Systems Security

This area evaluates your ability to secure operational technology environments, which differ significantly from traditional enterprise IT networks due to safety and availability priorities. Interviewers look for deep familiarity with industrial automation constraints, where system downtime can have physical consequences. Strong performance requires balancing modern cybersecurity defenses with the realities of legacy industrial machinery.

Be ready to go over:

• ICS/SCADA architecture – Understanding the Purdue Model and how security zones and conduits are established.
• Industrial communication protocols – Knowing how protocols like Modbus, DNP3, and OPC operate and their inherent security vulnerabilities.

As a Security Engineer at ABB, your day-to-day responsibilities revolve around delivering secure, high-quality, and cost-effective solutions for industrial automation and energy projects. You will provide consultative support to enterprise customers, helping them understand and apply cybersecurity solutions that enhance the resilience of their operational technology environments. This involves leading the implementation of security projects, ensuring they are delivered on schedule and within budget while maintaining strict compliance with industry standards.

Collaboration is a daily cornerstone of the role. You will work closely with cross-functional engineering teams, project managers, and the sales department to identify customer requirements and demonstrate how security offerings address specific operational challenges. Throughout the customer lifecycle—from initial onboarding through post-deployment—you will provide training and ongoing technical support to ensure successful adoption and long-term satisfaction. You will also oversee vulnerability management, drive secure digital platform integration, and champion continuous improvement across all engineering deliverables.

Meeting the qualifications for this position requires a blend of formal education, extensive hands-on experience, and specialized knowledge of industrial environments. The hiring team looks for candidates who can hit the ground running with both IT security principles and OT constraints.

• Must-have technical skills – Bachelor’s or higher degree in Cybersecurity, Computer Science, Electrical Engineering, or a related field. Minimum of 8+ years of experience in cybersecurity, with at least 3 years specifically focused on industrial automation or operational technology environments. Strong understanding of ICS/SCADA systems, industrial communication protocols, network security, and risk assessment methodologies.
• Industry frameworks and tools – Hands-on familiarity with OT security best practices, cybersecurity frameworks such as IEC 62443 and NIST, and cyber platforms including antivirus solutions, backup and recovery tools, and network monitoring systems.
• Soft skills and leadership – Demonstrated capability in customer consultation, cross-functional collaboration, and technical training. Strong communication skills to articulate complex security risks to both technical engineers and business stakeholders.
• Nice-to-have qualifications – Recognized professional cybersecurity certifications such as CISSP, GIAC, or ISA/IEC 62443. Prior experience in energy, power, water, or oil and gas industries.

Q: How difficult is the interview process for a Security Engineer at ABB?
