We are looking for an experienced Senior Network Security Engineer with a strong background in enterprise networking, firewall management, and infrastructure security. In this role, you will be responsible for designing, implementing, and maintaining secure network environments across hybrid infrastructures, including on-premises systems and Microsoft Azure cloud services.

The ideal candidate has hands-on experience with switching, routing, WLAN, and firewall technologies, particularly with HPE Aruba and Fortinet. Familiarity with NAC (e.g., Clearpass), reverse proxy systems (e.g., Netscaler), PKI, and certificate-based authentication is essential. Strong analytical thinking, a customer-oriented mindset, and the ability to work independently in complex environments are critical. Fluency in German and the ability to collaborate in English-speaking teams are required.

Our client offers a meaningful role within a forward-thinking IT services provider, delivering secure and modern infrastructure solutions to well-known organizations across Central Switzerland. You’ll work in a collaborative and supportive team, where knowledge sharing, personal development, and technical autonomy are highly valued. Flexible working options (up to 3 days remote), modern tools, and generous time-off policies support your wellbeing and work-life balance. You’ll have the opportunity to take full ownership of projects and help shape secure IT environments across cloud and on-prem deployments.
