Seeking a Senior Multi-Cloud Infrastructure and Security Architect for a contractor role. This individual will serve as a technical leader, translating high-level security requirements into practical, scalable cloud engineering solutions. The role is critical to ensuring the organization's systems are robust, resilient, and highly available.


Responsibilities :
1. Hybrid & Multi-Cloud Architecture Design

• Architect and implement secure, enterprise-grade multi-cloud infrastructure across AWS and Azure (Google Cloud Platform is a plus), ensuring alignment with benchmarks and corporate security policies.
• Adopt complex hybrid connectivity solutions to link on-premise and cloud based systems.
• Establish scalable IAM hierarchies, cross-account trust relationships, and organizational units across multiple cloud tenants.

2. Infrastructure Resiliency & Disaster Recovery (DR)

• Architect high-availability (HA) and disaster recovery topologies across disparate cloud providers to eliminate single points of failure (e.g., active-active cross-cloud replication).
• Develop, document, and test automated failover mechanisms for critical enterprise workloads to ensure zero-downtime objectives.

3. Infrastructure as Code (IaC) & Automation

• Define, build, and maintain the the IaC repository using automation platforms.
• Implement secure CI/CD deployment pipelines (Jenkins, GitHub Actions) embedded with automated security guardrails and static analysis tools.

4. Technical Advisory & Collaboration

• Serve as the primary subject matter expert (SME) on cloud infrastructure for the core Cyber Security team, translating security objectives into concrete cloud configurations.
• Collaborate with traditional on-prem network and sysadmin teams to systematically migrate or extend legacy workloads to the cloud without disrupting active operations.

Required Skills :

• Enterprise Scale: Minimum 8+ years of experience managing, architecture-designing, and deploying IT infrastructure within a Fortune 500 or equivalent large-scale enterprise.
• Multi-Cloud Mastery: Deep, hands-on production experience with at least two major cloud vendors (AWS and Azure are highly preferred). You know their native networking, identity systems, and edge security controls inside out.
• Networking: Strong foundational background in traditional on-premises networking (firewalls, load balancers, VLANs, proxies) and how those concepts map directly to cloud-native constructs (VPCs, VNets, Transit Gateways).
• Automation-First Mindset: Advanced proficiency with automation toolsets.
• Pragmatic Security Knowledge: While you don't need to be a penetration tester, you must thoroughly understand cloud security frameworks and modern identity protocols.
• Scripting & Systems Proficiency: Strong proficiency with Python programming, Shell scripting, and Unix/Linux operating systems.

Preferred Skills :

• AWS Certified Solutions Architect - Professional / AWS Certified Security - Specialty
• Microsoft Certified: Azure Solutions Architect Expert / Azure Security Engineer Associate

• Familiarity with Secure Email Gateway (SEG) products such as Proofpoint and Fortimail

• Experience with large-scale email broadcast or bulk-messaging platforms
• Exposure to compliance frameworks, audits, and regulatory examinations
• Experience integrating email platforms with monitoring, logging, and AIOps tooling
• Prior experience mentoring senior or mid-level engineers
• Ability to work independently on complex, ambiguous problems
