Merci de me contacter par email. We are seeking a highly experienced Senior Multi-Cloud Architect & DevOps Engineer with deep expertise in AWS and strong architectural proficiency in Azure. The primary mission is to design and implement a new AWS environment serving as a disaster recovery (DR) and emergency platform for a mission-critical workload currently operating in Azure's multi-region, zone-redundant configuration. In addition to DR design and implementation on AWS, the resource will support the continuous evolution of our Azure cloud architecture and our cloud platform automation ecosystem, ensuring both platforms remain aligned, resilient, secure, and ready for multi-cloud operations. This includes contributing to improvements in cloud foundations, automation patterns, IaC frameworks, and operational tooling. Key Task and Responsibilities The Scope Includes, But Is Not Limited To AWS Landing Zone Architecture & Design Define and design a full AWS multi-account landing zone aligned with the AWS Well-Architected Framework, enterprise security standards, and CIS compliance requirements. Implement identity, networking, governance, security, observability, logging, backup and disaster recovery patterns according to AWS best practices. Leverage reusable, vetted Terraform modules (AWS Verified Modules where suitable), reviewing, adapting or extending them to meet enterprise and CIS compliance requirements. Emergency Platform Architecture Translate the existing Azure architecture into an appropriate AWS disaster recovery blueprint. Define DR activation patterns, RTO/RPO expectations, data synchronization strategies, and a minimal baseline capacity to support rapid emergency activation. Azure Architecture & Platform Automation Evolution Provide architectural guidance on the existing Azure multi-region platform. Contribute to the evolution of cloud foundation components, IaC automation patterns, and platform engineering capabilities. Ensure architectural alignment between Azure production and AWS DR environments, with a focus on resilience, automation consistency, and operational readiness. Connectivity Architecture Evaluate and design secure Azure AWS connectivity options (e.g., IPSec VPN, ExpressRoute + cloud-to-cloud interconnect, SD-WAN integrations, or third-party cloud routing solutions). Define and document on-premises AWS connectivity approaches for emergency activation scenarios. Ensure routing, segmentation, traffic inspection, and security controls follow enterprise governance and CIS-aligned security requirements. Security & Compliance (CIS) Ensure the AWS environment meets CIS security benchmarks and internal cloud security baselines. Implement guardrails, preventive and detective controls, IAM boundaries, encryption standards, logging policies, incident readiness and compliance enforcement using IaC. Operations, Monitoring & Management Implement monitoring, alerting, log management, and operational readiness for AWS as an emergency platform. Align AWS observability with existing monitoring practices in Azure. Define and set up backup, restoration, and data retention policies following CIS benchmarks and enterprise resilience requirements. Infrastructure-as-Code (Terraform) Delivery Deliver the full AWS environment using Terraform with a Git-driven CI/CD pipeline (Azure DevOps or equivalent). Enforce best practices in module structure, reuse of AWS Verified Modules, versioning, testing, and environment promotion. Cross-Team Collaboration Collaborate with Cloud Architecture, Platform Engineering, Security, Network and Operations teams to ensure alignment with enterprise cloud policies and operating models. Produce high-quality design documentation, architectural decisions, operational runbooks, and DR activation procedures. Profil Candidat Job Requirements Technical Competencies and Experience Extensive experience designing enterprise-grade AWS landing zones and multiaccount environments. Strong hands-on engineering skills in Terraform, CI/CD, automation, cloud networking, and cloud-native security. Solid understanding of Azure architecture, including identity, networking, and multi-region designs. Proven experience with multi-cloud architectures and disaster recovery design. Strong understanding of Azure concepts and architecture to ensure proper mapping between platforms. Deep knowledge of hybrid and multi-cloud networking technologies (VPN, Direct Connect, ExpressRoute, SD-WAN). Experience implementing environments aligned to CIS benchmarks and enterprise security standards. Ability to work at both strategic architecture and detailed engineering levels
