Mission freelance Multi-Cloud Architect AWS & Azure

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

o Define and design a full AWS multi-account landing zone aligned with the

AWS Well-Architected Framework, enterprise security standards, and CIS

compliance requirements.

o Implement identity, networking, governance, security, observability,

logging, backup and disaster recovery patterns according to AWS best

practices.

o 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

o 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

o Provide architectural guidance on the existing Azure multi-region

platform.

o Contribute to the evolution of cloud foundation components, IaC

automation patterns, and platform engineering capabilities.

o Ensure architectural alignment between Azure production and AWS DR

environments, with a focus on resilience, automation consistency, and

operational readiness.

• Connectivity Architecture

o 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).

o Define and document on-premises ↔ AWS connectivity approaches for

emergency activation scenarios.

o Ensure routing, segmentation, traffic inspection, and security controls

follow enterprise governance and CIS-aligned security requirements.

• Security & Compliance (CIS)

o Ensure the AWS environment meets CIS security benchmarks and

internal cloud security baselines.

o Implement guardrails, preventive and detective controls, IAM boundaries,

encryption standards, logging policies, incident readiness and

compliance enforcement using IaC.

• Operations, Monitoring & Management

o Implement monitoring, alerting, log management, and operational

readiness for AWS as an emergency platform.

o Align AWS observability with existing monitoring practices in Azure.

o 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).

o Enforce best practices in module structure, reuse of AWS Verified

Modules, versioning, testing, and environment promotion.

• Cross-Team Collaboration

o Collaborate with Cloud Architecture, Platform Engineering, Security,

Network and Operations teams to ensure alignment with enterprise cloud

policies and operating models.

o Produce high-quality design documentation, architectural decisions,

operational runbooks, and DR activation procedures.
