AISB-680 Senior Infrastructure Architect (Hybrid On‑Prem & Cloud)

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
