The posting

Network Operations & Security Engineer | Critical Infrastructure

Zurich, Switzerland

Hybrid Working | Permanent Position

Would you like to operate and secure network infrastructure where availability, resilience and rapid incident response genuinely matter?

I am supporting a major Swiss organisation operating a large-scale, highly available and business-critical technology environment in the recruitment of a Network Operations & Security Engineer to join its ICT team.

This is not a standard corporate network environment. You will help keep mission-critical network and security services running 24/7, supporting infrastructure and services relied upon by thousands of people every day.

You will work across Cisco networking, LAN, WLAN, routing, switching, VPN, firewalls, data centre infrastructure and network security, while collaborating closely with experienced Network Engineering specialists on projects and the continued development of the environment.

What you will be doing

  • Operate and maintain a highly available Network & Security infrastructure
  • Resolve complex incidents within 2nd and 3rd Level Support
  • Troubleshoot network, performance and security issues in a mission-critical environment
  • Work hands-on across LAN, WLAN, routing, switching, VPN and firewall technologies
  • Participate in 24/7 incident management and an on-call rotation of approximately 10–12 weeks per year
  • Handle service requests across switching, routing and IT security
  • Work closely with Network Engineering specialists on infrastructure and security projects
  • Independently support projects from planning through implementation and successful commissioning
  • Contribute your operational expertise to improvements in the stability, performance and security of the environment
  • Gain further exposure to network automation and modern infrastructure technologies

What we are looking for

  • At least 3 years of professional experience within Network Operations, Network Engineering and/or Network Security
  • Strong hands-on experience within complex enterprise network environments
  • Good practical knowledge of LAN, WLAN, routing, switching, VPN and firewalls
  • Strong Cisco networking experience
  • Technical expertise operating around CCNP level
  • Experience with some of the following would be highly advantageous:
  • Cisco ASA
  • Cisco Firepower
  • Cisco ACI
  • A10 Load Balancers
  • Web Application Firewalls (WAF)
  • Network automation
  • Strong troubleshooting and analytical capabilities
  • A structured, solution-oriented approach, particularly when handling complex or time-critical incidents
  • Confident German (at least C1 level) and good English
  • Category B driving licence

Why consider this opportunity?

Critical infrastructure

Work in an environment where network availability, performance and security have a genuine operational impact.

Broad Network & Security exposure

Work across networking, firewalls, VPN, WLAN, data centre infrastructure and security rather than being restricted to one narrow technology area.

Complex technical environment

Gain exposure to large-scale, highly available infrastructure considerably more sophisticated than a typical corporate network.

Operations + Projects

Remain genuinely hands-on while also contributing to infrastructure projects and working closely with specialist Network Engineering colleagues.

Professional development

Benefit from financial and time-based support for further education, internal training and continued technical development.

Hybrid & flexible working

Flexible working hours together with remote-working possibilities.

Excellent holiday flexibility

5 weeks of annual leave, with the possibility to purchase up to 30 additional vacation days and options for extended unpaid leave.

Travel benefits

Excellent public transport benefits, GA contribution and parking facilities.

Health & wellbeing

Free internal sports programmes, discounted fitness facilities and attractive insurance benefits.

Employee benefits

Access to attractive discounts across food, shopping and other services within a unique working environment.

Why it works

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
