We believe you bring:

• Solid experience in network, infrastructure and security technology
• Swedish and good English, both spoken and written
• Working knowledge of routing & switching (e.g. CCNA level)
• Experience with infrastructure security technology
• The ability to work in a structured and careful way, even when things get complex
• Good communication skills and enjoyment of working together with others

Technologies you will work with:

• Web proxy and secure internet access solutions
• IDS / IPS technologies
• Working together with Security, Network monitoring and management tools
• WAN, LAN and wireless environments
• ITIL‑based operational processes
• Basic scripting or automation (nice to explore over time)

On‑call duty is part of the role and will be introduced gradually with proper support.

• Based at our Solna office next to Arena stad or - in any Vattenfall IT country for Swedish speakers.
• Hybrid working model (not fully remote)
• Occasional travel for team or project meetings (on average once per month)
