Senior multi-cloud infrastructure & security architect
12-month initial contract with high likelihood of extension.
Location: New York City
The Cybersecurity team is responsible for safeguarding a complex global organization. Although the current team excels in threat mitigation, incident response, compliance, and governance, the company is undergoing a significant transformation of its infrastructure. This initiative involves expanding from a legacy on-premises environment to a robust, multi-cloud ecosystem across leading global cloud service providers.
While the organization possesses deep security expertise, there is a need for a highly skilled professional in cloud architecture and enterprise IT infrastructure to design and implement secure and resilient cloud solutions.
The company is seeking a Senior Multi-Cloud Infrastructure and Security Architect for a full-time contractor role. This individual will serve as the 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.
Key Responsibilities
Key Responsibilities
1. Hybrid & Multi-Cloud Architecture Design
• Architect and implement secure, enterprise-grade multi-cloud landmines—er, landing zones—across AWS and Azure (Google Cloud Platform is a plus), ensuring strict alignment with CIS benchmarks and corporate security policies.
• Design and deploy complex hybrid connectivity solutions (e.g., AWS Direct Connect, Azure ExpressRoute, SD-WAN, and high-throughput VPN meshes) to link our legacy on-premises data centers smoothly with cloud environments.
• 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 company''s master IaC repository using Terraform, Ansible, or CloudFormation.
• Implement secure CI/CD deployment pipelines (Jenkins, GitLab, or 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 & Experience
• 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 Guru: 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 (NIST, Cloud Security Alliance CCM) and modern identity protocols (SAML, OIDC, OAuth, JIT access).
Desired Certifications
(While your hands-on experience matters most, we highly value the following credentials)
• AWS Certified Solutions Architect – Professional / AWS Certified Security – Specialty
• Microsoft Certified: Azure Solutions Architect Expert / Azure Security Engineer Associate
• CCSP (Certified Cloud Security Professional) or equivalent infrastructure-focused certifications
Preferred / Plus Qualifications
• Familiarity with Microsoft Exchange On Premises and Exchange Online environments
• 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
Key Attributes
• Ability to work independently on complex, ambiguous problems
• Strong analytical and troubleshooting skills
• Excellent written and verbal communication skills
• Self driven learner with curiosity for modern tooling and AI assisted development
• Collaborative mindset with the ability to influence across teams and functions
Why Join Us
• Work on mission critical, globally distributed email security platforms
• Solve complex security and compliance challenges at enterprise scale
• Collaborate with highly skilled engineers in a strong engineering culture
• Opportunity to shape the long term evolution of enterprise email security architecture
