Mission

Join a transformation program aiming to strengthen the coherence, resilience, and security of a strategic technical foundation. You will be the reference for infrastructure architecture across on‑premise and IaaS cloud environments, partnering with enterprise architecture, project teams, hosting factories, and operations to build a robust, governed, and secure platform.

What You’ll Do

1) Solution Studies & Architecture

• Translate business needs into compliant, secure, and standard‑aligned infrastructure solutions.
• Co‑design with technical and application designers; produce, review, and validate architecture deliverables (HLD/LLD).
• Ensure IT & security compliance (incl. ISO 27001), define scope and deliverables, and maintain a clear map of the existing landscape.
• Identify gaps between the current state and target solutions, and contribute to effort and cost estimates .
• Present solutions to the Architecture Committee and IT leadership.

2) Project Guidance & Risk Management

• Present infrastructure architecture in the design phase to project and factory teams.
• Identify, track, and mitigate risks ; manage impacts of Change Requests .
• Guarantee the quality and completeness of technical documentation; contribute to Lessons Learned .

3) Run, Maintenance & Evolution

• Steer the maintenance and continuous evolution of the infrastructure architecture with the same governance and quality principles.

4) Infrastructure Governance

• Define and maintain infrastructure architecture principles and governance (naming, tagging, policies, standards).
• Actively participate in the architecture guilds/working groups .

5) Enterprise Architecture Contribution

• Share lessons learned with enterprise and IT architects to enrich the reference architecture .
• When relevant, define technical requirements and scope for RFI/RFP , and support workshops, offer analysis, negotiations, and costings .

Tech Environment You’ll Shape

• Virtualization: VMware vSphere, Hyper‑V
• Backup & DR: Veeam, Veritas; BCP/DRP practices
• Databases: Oracle, Microsoft SQL Server
• Operating Systems: Windows Server, Linux
• Physical Infrastructure: compute, storage (SAN/NAS), network
• Cloud: Hybrid environment with Azure components (Hub & Spoke, Policies, RBAC)
• Automation: Terraform, Ansible; advanced PowerShell
• Security & Compliance: ISO 27001 , GDPR, identity & access (AD on‑prem, Azure AD, Conditional Access)
• Observability: SCOM, Zabbix, Grafana
• Networking: VLAN, routing, firewalling, DMZ, QoS
• Modern paradigms: Containerization (on‑prem & cloud), DevOps/CI‑CD (Azure DevOps), HCI/SDN/SASE, Green IT mindset

What You Bring

Must‑Have

• Proven experience as an Infrastructure/Solutions Architect in complex hybrid (on‑prem / cloud) environments ( 5+ years ).
• Continuity & performance expertise: BCP/DRP, backups, high availability, capacity planning, KPIs, and solid technical documentation .
• Modeling skills (UML) and architecture documentation (TAD/HLD/LLD).
• Strong foundations in virtualized infrastructures (VMware, Hyper‑V), storage SAN/NAS (RAID, zoning, multipathing, dedup).
• Security & governance for infrastructures: AD/GPO, PKI, DNS/DHCP, hardening, patching, ISO 27001/GDPR , Azure Policies, RBAC.
• French C2 (CEFR).

Should‑Have

• Network architecture & segmentation: VLAN, routing, firewalling, DMZ, QoS.
• English B1+ .

• Monitoring & identity: SCOM, Zabbix, Grafana, AD/Azure AD, Conditional Access.

Nice‑to‑Have

• Continuous audit & compliance experience.
• Automation & migrations: PowerShell at scale, datacenter migrations , exposure to OT environments.
• Certifications & methodologies: TOGAF, ITIL, VMware VCP, Cisco CCNP , Green IT.
• Energy sector exposure, vendor/partner management, RFI/RFP authoring & follow‑up.
• Tech watch & DevOps culture (HCI, SDN, SASE, AI, Cloud, Azure DevOps CI/CD ).

Soft Skills

• Autonomy, proactivity, rigor ; ability to prioritize and deliver.
• Clear communication with technical teams and executives .
• Team spirit, active listening , and stakeholder alignment.
• Stress resilience and assertiveness in governance settings.

Why This Role?

• Direct impact on resilience, security, and coherence of a strategic infrastructure.
• Work across enterprise, project, and run horizons with strong governance exposure.
• Opportunity to standardize and modernize a hybrid platform at scale.
