Scope of Role

ITRS is looking for a Systems & Network Administrator to own and run our mobile platform, network infrastructure and mobile device fleet in Paris, and to keep them performing without interruption.

Reporting to the IT Manager, you will be responsible for the day-to-day health of the mobile platform and the network that supports it. We are looking for someone with strong network infrastructure expertise, who can design and build a complete network from the ground up, not only maintain one.

As a Systems & Network Administrator, you will:

• Oversee and maintain the mobile platform, network infrastructure and fleet of mobile devices to guarantee continuous operational performance.
• Design, build and document network infrastructure, from architecture and addressing through to switching, routing, firewalls and wireless.
• Monitor platform and network health, and find and fix the root cause of incidents rather than only the symptoms.
• Supervise and work closely with the Operations Team dedicated to the mobile platform.
• Train, guide and work daily with the apprentice assigned to the mobile platform, building their skills on the job.
• Support the IT Manager on-site in our data-centers whenever hands-on support, hardware maintenance or troubleshooting is needed.
• Provide Tier 1 to Tier 3 support to users and infrastructure, and escalate or resolve issues at the right level.
• Take an active part in core IT team projects, and deliver the ones you own on time.
• Handle daily technical communication in English with international teams, keeping colleagues informed on changes, incidents and progress.
