Job Description

Want to help shape how cyber incident response is documented and delivered in a global 24/7 Security Operations Center? Wärtsilä is looking for a Technical Writer to support its Security Operations Center (SOC)!

What will you be doing?

In this role, you will help transform operational knowledge into clear, practical documentation that enables consistent and effective cyber incident response across Wärtsilä’s global business ecosystem.

You will work closely with Wärtsilä’s Tier 3 cyber security specialists and other subject matter experts to create and maintain SOC playbooks, service descriptions, process documentation and operational guidelines. While the technical content comes from experienced cyber security professionals, your responsibility is to structure, document, and communicate that knowledge in a way that is easy to understand and apply.

The role is part-time, averaging approximately 20 hours per week, and offers a unique opportunity to gain exposure to advanced cyber security operations while collaborating with experienced incident response professionals.

What makes you a great fit?

Ideally you already have some experience producing technical documentation and enjoy turning complex topics into structured, user-friendly content. You are comfortable collaborating with multiple stakeholders, gathering information from experts, and driving documentation tasks forward independently.

An understanding of cyber security incident response processes will help you succeed in the role. You do not need to be a senior incident responder, but familiarity with how security incidents are investigated, managed, and mitigated will allow you to contribute more effectively from day one.

We expect you to have:

• Experience creating and maintaining technical documentation, operational procedures, or process documentation
• Understanding of cyber security incident response, SOC operations, or related security functions
• Ability to collaborate with technical subject matter experts and translate information into clear documentation
• Structured, detail-oriented, and proactive working style
• A full working proficiency in English, both verbal and written

We consider as an asset:

• Previous experience working in a SOC, CSIRT, cyber security, or incident response environment
• Familiarity with documentation and collaboration platforms such as Confluence, SharePoint, ServiceNow, M-Files, or similar tools
• Understanding of malware investigations, account compromise incidents, cyber threat response, or related security topics

Why join us?

• Learn directly from experienced cyber security specialists while building expertise in incident response documentation
• Contribute to a global 24/7 security operation protecting critical business services and assets
• Work in a flexible hybrid model while collaborating with an international team
• Gain exposure to modern cyber security platforms, processes, and service development initiatives

Practicalities:

This is a fixed-term, part-time position lasting until the end of 2026, and you will be employed by aTalent while working as part of Wärtsilä’s Cyber Operations organization. The expected workload is approximately 20 hours per week, with flexibility depending on project needs. Preferred starting date is in August, 2026. The role can be performed fully remotely from Finland, although you are also welcome to work from Wärtsilä’s Helsinki office if preferred.

Sounds like you? Please submit your CV in PDF-format in English by latest 11th of June via our application system.
