Job Description: Cloud Infrastructure Architect AWS Migrations & Platform Modernization

Position Overview

We are seeking a highly skilled Cloud Infrastructure Architect with deep expertise in designing, planning, and executing large-scale migrations to AWS. The ideal candidate has led complex On-Prem AWS migrations and intra-AWS migrations, including moving workloads from shared-tenant environments to AWS Dedicated Hosts.
This role requires strong architecture leadership, hands-on technical proficiency, and the ability to support large-scale Kubernetes platforms and enterprise AWS workloads while ensuring security, scalability, and operational excellence.

Key Responsibilities Cloud Architecture & Design

• Architect end-to-end infrastructure solutions leveraging AWS Well-Architected Framework and enterprise design patterns.
• Design scalable, secure multi-account landing zones, VPC architectures, enterprise networking, and workload isolation strategies.
• Provide architecture leadership for containerized platforms, including Amazon EKS and large-scale self-managed Kubernetes clusters.

Migration Leadership

• Lead complex On-Prem AWS and intra-AWS migrations involving VPC redesigns, account realignments, multi-region moves, and host architecture changes.
• Drive migrations from shared-tenant EC2/EKS deployments to AWS Dedicated Hosts, ensuring compliance, performance, and workload isolation.
• Conduct infrastructure assessments, migration strategies (rehost, replatform, refactor), and detailed cutover planning.

AWS Dedicated Host Expertise

• Design and manage workloads running on AWS Dedicated Hosts, including host allocation, tenancy planning, compliance alignment, and lifecycle management.
• Optimize compute planning, licensing models, capacity strategies, and high-availability architectures using Dedicated Hosts.
• Ensure secure and compliant hosting for sensitive workloads requiring physical isolation and regulatory controls.

Kubernetes & Platform Engineering

• Architect and manage large, multi-cluster Kubernetes environments with enterprise-grade reliability and security.
• Define compute and scaling strategies using EC2, EKS, Bottlerocket, autoscaling groups, and Dedicated Hosts backed node groups.
• Implement service mesh, workload identity, observability architectures, and cluster lifecycle automation.

Governance, Security & Compliance

• Develop and enforce IAM architectures, guardrails, cloud governance, and security policies aligned with CIS, NIST, and organizational standards.
• Partner with Security and Compliance teams to implement hardening, encryption, network segmentation, and threat detection.

Operational Excellence

• Lead performance tuning, capacity planning, resiliency engineering, and availability design for large-scale AWS workloads.
• Define operational playbooks for deployments, monitoring, backups, DR/HA, and workload lifecycle management.
• Mentor engineering teams on AWS architecture patterns, DevOps practices, and migration execution.

Cross-Functional Leadership

• Serve as a trusted advisor to engineering, SRE, product, and executive leadership.
• Partner with AWS teams and vendors to drive best practices and architectural decisions.
• Communicate complex solutions clearly to both technical and non-technical audiences.

Required Qualifications

• 8+ years of experience in Cloud Architecture, Infrastructure Engineering, or Platform Engineering.
• 5+ years of advanced AWS experience across EC2, VPC, IAM, EKS, RDS, Route53, S3, CloudWatch, CloudTrail, Config, and related services.
• Proven experience leading large-scale AWS migrations, including On-Prem AWS and shared-tenant Dedicated Host transitions.
• Deep hands-on expertise with AWS Dedicated Hosts, tenancy management, licensing considerations, and infrastructure lifecycle planning.
• Strong proficiency with Kubernetes, Terraform, cloud networking, and infrastructure automation.
• Excellent understanding of multi-account governance, security controls, and workload isolation.
• Strong communication and architectural leadership skills.

Preferred Qualifications

• AWS Solutions Architect Professional, DevOps Engineer Professional, or equivalent certifications.
• Experience with large-scale Kubernetes operations, cluster bootstrap and upgrades, and production reliability.
• Familiarity with service mesh (Istio, Linkerd, App Mesh), GitOps tools (ArgoCD, Flux), and cloud-native observability tools.
• Experience designing resilient, cost-optimized, multi-region AWS architectures.
