🏢 About Wartsila

Wärtsilä is a global leader in innovative technologies and lifecycle solutions for the marine and energy markets, uniquely positioned to drive the transition towards a decarbonized and sustainable future. Working here means contributing to cutting-edge automation and control systems that power critical infrastructure, with a strong commitment to environmental responsibility.

About This Role

As a Product Security Expert, you will be the go-to authority for cybersecurity in engine power plant automation and control systems, directly shaping product features to meet rigorous standards like IEC 62443 and EU CRA. Your work ensures that Wärtsilä's products remain compliant, competitive, and secure, making a tangible impact on global energy sustainability.

💡 A Day in the Life

Your day might start with a review of the latest vulnerability disclosures affecting industrial control systems, then a meeting with the development team to discuss security feature implementation for a new power plant automation release. Later, you could prepare a training session for sales engineers on the EU CRA requirements, followed by a risk assessment of a legacy product against IEC 62443.

1

Highlight specific experience with IEC 62443 and EU CRA compliance in your resume and cover letter, using concrete examples of how you've implemented these standards.

3

Showcase your ability to translate regulatory requirements into product roadmaps by describing a past project where you drove security features from concept to delivery.

4

Tailor your CV to include keywords like 'vulnerability handling', 'product security', 'automation systems', and 'cyber legislation' to pass ATS filters.

5

Prepare a brief portfolio or case study of a security implementation you led, demonstrating your hands-on experience with automation control systems.

⚠️ Common Mistakes to Avoid

  • Focusing too much on IT security (e.g., network firewalls, endpoint protection) without demonstrating OT/ICS-specific experience.
  • Being vague about standards compliance; instead, provide concrete examples of how you've applied IEC 62443 or similar.
  • Failing to mention your ability to communicate with non-technical stakeholders, which is critical for this cross-functional role.
