Job description

On behalf of a partner company, Nordic Investin is looking for a Senior OT Cybersecurity Specialist. You understand that securing operational technology starts with availability, safety and the physical process the systems control.

The partner operates industrial environments that are becoming more connected. You will assess risk, improve segmentation and access, and help engineering and operations teams strengthen security without disrupting production.

Security work is expected to reduce real exposure while preserving the organisation’s ability to deliver. The strongest candidates can connect a technical weakness with a credible threat, an appropriate control and a practical path to implementation.

How you will work

You will work directly with the people who design, operate and depend on the systems being protected. Recommendations must identify the threat, the affected asset and a realistic implementation path. The partner values careful evidence, proportionate controls and clear escalation when risk cannot be removed immediately.

As a senior colleague, you will own substantial outcomes and help others make stronger decisions. You are expected to recognise risk early, communicate it without drama and move work forward with practical alternatives. The role still includes hands on delivery; seniority here means broader judgement, not distance from the work.

What you will do

• Assess industrial networks, assets and remote access paths.
• Develop practical segmentation and secure architecture designs.
• Guide hardening, patching and compensating control decisions.
• Support monitoring and incident readiness for OT environments.
• Translate standards into site level improvement plans.
• Work with operations, automation, IT and suppliers.

What you will bring

• Experience securing or engineering industrial control systems.
• Knowledge of PLC, SCADA and industrial network concepts.
• Understanding of IEC 62443, NIS2 or comparable requirements.
• Ability to assess risk in safety and availability critical settings.
• Strong network and identity security fundamentals.
• Professional English; Swedish is often valuable for site work.

Experience that would add value

• Energy, manufacturing, transport or process industry experience.
• OT incident response or threat detection.
• Industrial automation engineering background.

A background that can succeed here

You may come from cybersecurity and have built strong industrial understanding, or from automation and have specialised in security. The partner values people who respect how plants operate and can earn trust on site.

What makes the opportunity interesting

The role combines strategic security work with physical environments where improvements matter. You will influence investment plans and implement controls that protect essential operations.

The exact partner, employment model, compensation, start date and working arrangement will be explained openly during the process. Nordic Investin will make sure you understand the context, expectations and decision path before you are asked to commit significant time.

The recruitment conversation

During the process, Nordic Investin will focus on concrete decisions you have made: the context you received, the alternatives you considered, the result you observed and what you would change today. You do not need every optional technology if your core experience transfers and you can explain how you would close the gap.
