The company plays an important role in keeping Danish businesses connected and secure -supporting everything from everyday operations to critical infrastructure across different sectors.

Our team in Vilnius is an integrated part of this setup, working closely with colleagues in Denmark. It’s a hands-on environment with a strong focus on ownership and steady development of technical expertise.

- Ability to handle incidents independently and take ownership

- A practical, problem-solving mindset

- Willingness to learn and share knowledge with others

- Good understanding of ITIL processes

- Great command of English

Additional experience that would be highly valued

Hands-on experience with Cisco networking (CCNA or CCNP level, or equivalent practical experience)

Experience working with network security solutions (e.g. Fortinet, Palo Alto or similar)

Experience using ITSM tools such as ServiceNow

This role will suit you if you

- Are ready to step up from standard support into more technical work

- Want to build stronger expertise in networking and security

- Take ownership and are comfortable working independently

- See value in knowledge sharing and team collaboration

Your impact

- Handle more complex issues and follow them through end-to-end

- Support teammates and share practical knowledge

-Help improve daily ways of working

- Contribute to a stable and well-functioning team

What we offer

- A friendly, supportive team where knowledge sharing is part of everyday work

- Close collaboration with experienced engineers in Denmark

- Real opportunities to grow into L2/engineering roles

- Learning and certification support

-Hybrid work and a modern office in Vilnius

- Private health insurance and team events
