Senior OT / ICS Security Consultant

Do you want to work with OT security and help build a safer digital society? Then we have the job for you.

At Orange Cyberdefense, we lead the effort to secure the OT environments that keep the world running—from energy and water to manufacturing, transportation, and process industries.

You will become part of an established OT team where we share knowledge, grow together, and help drive the industry forward.

What will you do?

As a Senior OT Security Consultant, you will work closely with our customers, often directly within their OT environments. Assignments are both national and international, meaning travel and on-site customer presence are a natural part of the role—often for several consecutive days during project execution phases.

Your responsibilities will include:

- Trusted OT Security Advisor

Act as a long-term, trusted advisor to our customers on strategic and operational security matters. You will help them understand their threat and risk landscape, prioritize security initiatives, and make informed decisions that balance security, operational requirements, and regulatory obligations such as NIS2 and standards including IEC 62443.

- On-Site OT Security Assessments

Lead and perform in-depth security, risk, and vulnerability assessments at customer sites. This includes:

• Architecture and network reviews based on the Purdue Model

• Asset and data flow mapping

• Evaluation of network segmentation and remote access solutions

• Interviews with operations and maintenance personnel

• Gap analyses against relevant frameworks and standards

• Development of risk-based, prioritized remediation roadmaps that customers can execute

- Participation in Customer Cybersecurity Projects

Provide OT security expertise within customer-led initiatives, including network segmentation projects, secure remote access implementations, OT SOC establishment, IDS/asset discovery deployments, and compliance programs related to NIS2 and IEC 62443.

Depending on project needs, you will alternate between the roles of advisor, reviewer, and hands-on technical specialist.

- Project Management and Delivery

Drive engagements from scoping through delivery, lead cross-functional teams, and ensure high quality in both technical execution and documentation. You are comfortable presenting findings and recommendations to audiences ranging from technical specialists to executive leadership teams.

- Service Development

Contribute to the continuous development of our OT services and methodologies, evaluate new tools and technologies, and share knowledge internally across the team.

Who are you?

- Experience in OT/ICS security, or extensive experience in industrial automation with multiple years focused on cybersecurity. Previous experience in a consulting or advisory role is highly valued.

- - OT and Automation Expertise, for example SCADA, DCS, and PLC systems, including how they are operated, maintained, and secured. You are well-versed in the Purdue Model and understand the operational requirements of industrial environments.

- Security and Framework Knowledge

- Assessment Experience. Experience leading or conducting on-site OT security assessments, from planning and data collection through reporting and remediation recommendations.

- Certifications. Relevant certifications are considered an advantage, such as GICSP, ISA/IEC 62443, CISSP, CISM, or equivalent.

Who are you?

You are self-driven, solution-oriented, and business-minded. You take ownership, are confident in customer-facing situations, and have the ability to build long-term trusted relationships.
