• Strong understanding of enterprise data classification, encryption standards, and key management in cloud environments.
• Proven experience supporting or leading data center exit and application modernization programs.
• Strong documentation skills and ability to produce architecture diagrams, standards, reference architecture, and runbooks.
• Strong communication and stakeholder management skills.
• Ability to communicate complex cloud architectures clearly to both technical teams and executive leadership.

Nice To Haves

• Experience in financial services or automotive industries preferred.
• Master’s degree preferred.

Responsibilities

• Lead end-to-end cloud architecture for new and existing workloads, including reference architectures, patterns, and technical standards.
• Architect highly available and resilient systems using services such as ELB/ALB/NLB, Auto Scaling, ECS/EKS, Lambda, RDS/Aurora, DynamoDB, S3, and CloudFront.
• Collaborate with stakeholders to translate requirements into solution designs, estimates, risks, and implementation roadmaps.
• Provide technical leadership through design reviews, mentoring, and hands-on guidance.
• Perform cost optimization and capacity planning (FinOps): tagging, budgets, Reserved Instances/Savings Plans, right-sizing, and cost allocation reporting.
• Plan and execute migrations and modernization (re-host, re-platform, re-factor) and data transfer approaches using AWS migration tooling.
• Define disaster recovery architectures including workload tiering, RTO/RPO alignment, and cross-region failover patterns.
• Design secure landing zones and multi-account strategies using AWS Organizations, SCPs, IAM, networking, logging, and guardrails.
• Define network and connectivity designs (VPC design, Transit Gateway, Direct Connect/VPN, private connectivity, DNS) aligned to performance and security needs.
• Establish infrastructure-as-code and configuration standards using Terraform and/or AWS CloudFormation; promote reusable modules and CI/CD automation.
• Lead development, implementation, and management of project-based strategies to achieve HCA’s Digital Division goals.
• Compile and facilitate executive reporting and visibility on department and division initiatives and KPIs to ensure progress and alignment.
• Implement security best practices: least privilege IAM, KMS encryption, secrets management, WAF/Shield, vulnerability management, and security monitoring (e.g., GuardDuty, Security Hub).
• Own cloud governance and compliance alignment (e.g., ISO, SOC 2, PCI, HIPAA as applicable), including evidence collection and control mapping.
• Partner with Platform Engineering, DevSecOps, and Architecture Review Board (ARB) teams to ensure architectural standards are implemented through reusable patterns, automation frameworks, and governed exception processes.
• Establish and maintain cloud architecture standards, patterns, and reference architectures, aligned with AWS Well-Architected Framework, enterprise architecture principles, and financial services best practices.
• Produce and maintain clear cloud architecture documentation, including solution designs, reference architectures, migration runbooks, implementation plans, and operational handoff artifacts; participate in Architecture Review Boards (ARB) and technical governance forums.
• Lead architecture reviews and document design risks, exceptions, and approved deviations through ARB governance.
