Systems & Networks Engineer (M/F)

Permanent contract - Executive status

📍 Les Ulis (91) – on-site, 1 day of remote work per week after validation of the probationary period
💶 €50,000 to €65,000 gross annual salary, depending on profile

Informadis, a company of the E.Leclerc Movement, is the telecom operator, integrator, maintainer, and host (2 datacenters) for E.Leclerc stores. We are strengthening our IT Engineering team and recruiting two Systems & Networks Engineers.

You will design Informadis's products and technical solutions: you will define architectures and reference configurations, document them, write procedures that the teams will then apply, and intervene as a Level 3 expert in your area. Each of the two positions has a focus on systems or networks, with an interest in the other: projects touch upon both.

Areas of Intervention

Systems

• Develop installation and migration procedures for client servers to Windows Server 2025

• Design and evolve reference servers for the catalog

• Define the standardized domain, group strategies, and workstation management (Active Directory, GPO)

• Design and size remote desktop farms (RDS) for stores

• Lead the migration from VMware virtualization to Datacenter Virtualization Solution (DCS), and enhance storage, backup, and monitoring reliability

• Develop PowerShell scripts for deployment and migration

Networks

• Design store network architecture: switching, VLAN, routing, addressing plan

• Develop switch reference configurations and replacement procedures

• Define security rules and remote access on Fortinet firewalls

• Design inter-site links and the hosting network

• Evolve the internal telephony platform (Asterisk) and build the operator SIP trunk infrastructure (interconnection, SBC) by 2027

Design, Documentation, and Compliance

• Establish recommendation rules used by pre-sales and estimate deployment times

• Write operational documentation and procedures, and transmit them to the teams that apply them

• Validate the technical feasibility of recommendations and support complex cases

• Translate ISO 27001 and NIS2 requirements into technical rules within your scope

• Provide Level 3 expertise within your scope

No on-call duty. Occasional travel (stores, datacenters) may be required depending on projects: analysis, pilot, testing.

Your Profile

• Master's degree (engineering school or equivalent), 5 years of minimum experience in a company, outsourcing, or integration

• Systems focus: Windows Server, Active Directory, GPO, and RDS. Virtualization and PowerShell appreciated

• Networks focus: switching, routing, VLAN, and firewalls. Fortinet and ToIP/SIP appreciated

• A knack for design, formalization, and knowledge transfer: the ability to write a procedure that another can follow without your direct involvement

• Mastery of both domains is not required. Certifications are appreciated, not required

What We Offer

• Executive status

• Smartphone (iPhone or Samsung, choice) and laptop

• Health insurance 100% covered

• Meal vouchers

• Gratuity bonus and profit-sharing bonus

• 1 day of remote work per week after validation of the probationary period
