The role emphasizes hands-on architecture, cost optimization, and enabling self-service infrastructure across multiple cloud environments. You'll lead multi-account AWS design, landing zones, and security controls, with Terraform-driven automation and Kubernetes

Qualifications

• 8+ years of cloud architecture, platform engineering, or infrastructure experience.
• Strong experience designing and governing multi-account AWS environments.
• Advanced Terraform experience for enterprise-scale automation.
• Strong AWS networking knowledge across VPCs, Transit Gateway, Direct Connect.
• Experience with managed Kubernetes platforms such as EKS.
• Ability to define architecture while remaining technically hands-on.
• Experience operating within large, complex enterprise environments.

Responsibilities

• Own the architecture and evolution of a large-scale, multi-account AWS environment.
• Design AWS Organizations structures, account provisioning, landing zones, and governance controls.
• Build automated cloud foundations using Terraform and IaC.
• Architect enterprise cloud networking across VPCs and hybrid environments.
• Define cloud security standards across identity, access, threat detection, and network security.
• Develop reusable infrastructure modules and automation patterns for engineering teams.
• Establish scalable cloud governance, naming, tagging, and compliance standards.
• Drive cloud cost optimization and infrastructure efficiency.
• Enable engineering teams through self-service infrastructure and architecture guidance.

Job description

Compensation: $200,000–$215,000 base + bonus + equity

About the Company

This established enterprise organization is making a significant investment in the modernization of its cloud infrastructure and platform engineering capabilities.

The technology organization is building a secure, automated, and scalable cloud foundation that enables engineering teams to consume infrastructure through standardized, self-service patterns. The environment is AWS-first while supporting Azure and GCP where appropriate, creating an opportunity to influence cloud strategy across a large and complex technology ecosystem.

The culture emphasizes technical ownership, strong engineering standards, automation, security, and giving architects the ability to remain hands-on while setting long-term technical direction.

About the Role

This is a senior, hands-on architecture role with ownership over the evolution of the enterprise public cloud platform.

You'll define how cloud infrastructure is designed, governed, automated, secured, and consumed across the organization, with AWS as the primary platform. You'll own architecture across multi-account environments, landing zones, networking, security, Infrastructure as Code, Kubernetes, cost governance, and developer enablement.

This isn't an architecture role where you'll simply produce diagrams. You'll remain close to the technology, build reusable infrastructure patterns, establish engineering standards, and enable application teams to consume cloud services securely and at scale.

Key Responsibilities

• Own the architecture and evolution of a large-scale, multi-account AWS environment
• Design AWS Organizations structures, account provisioning, landing zones, and governance controls
• Build automated cloud foundations using Terraform and Infrastructure as Code
• Architect enterprise cloud networking across VPCs, private connectivity, segmentation, and hybrid environments
• Define cloud security standards across identity, access, threat detection, configuration, and network security
• Develop reusable infrastructure modules and automation patterns for engineering teams
• Establish scalable cloud governance, naming, tagging, and compliance standards
• Drive cloud cost optimization and infrastructure efficiency
• Enable engineering teams through self-service infrastructure, reusable patterns, documentation, and architecture guidance
• Support Kubernetes-based workloads across managed cloud environments
• Extend cloud governance and architectural patterns across Azure and GCP where required
• Partner with engineering, security, infrastructure, and business teams on major cloud architecture decisions

Must Haves

• 8+ years of cloud architecture, platform engineering, or infrastructure experience
• Strong experience designing and governing multi-account AWS environments
• Experience with AWS Organizations, Control Tower, landing zones, and automated account provisioning
• Advanced Terraform experience for infrastructure automation at enterprise scale
• Strong AWS networking knowledge across VPCs, Transit Gateway, Direct Connect, and private connectivity
• Experience implementing enterprise cloud security and IAM controls
• Experience with managed Kubernetes platforms such as EKS
• Strong understanding of CI/CD and GitOps infrastructure deliveryAbility to define architecture while remaining technically hands-on
• Experience operating within large, complex enterprise environments

Nice to Have

• Azure or GCP cloud architecture experience
• CloudFormation
• FinOps and cloud cost optimization
• Cloud security and compliance frameworks
• Advanced network security architecture
• Cloud observability and monitoring
• Identity federation and Zero Trust architecture
• OpenShift
• GPU or high-performance computing infrastructure
• Internal developer platforms and self-service cloud tooling
• AWS Professional-level or equivalent cloud certifications

Why Join

• Own the architecture of an enterprise-scale public cloud platform
• Define the organization's future-state AWS strategy rather than simply maintaining an existing environment
• Build the automation, governance, and self-service capabilities used by engineering teams across the business
• Remain technically hands-on while having significant architectural influence
• Work across AWS, Terraform, Kubernetes, cloud networking, security, automation, and multi-cloud architecture
• Solve complex challenges around scale, security, developer experience, and cloud economics
• High-visibility opportunity with significant ownership over long-term cloud strategy
