Responsibilities
- AWS Platform Ownership
- Own the AWS platform roadmap inside DIGITALcore: define priorities, epics, and release plans for the Landing Zone and AWS platform services.

- Align AWS platform priorities with DIGITALcore system governance, enterprise architecture, and security/compliance stakeholders.
- Secure Landing Zone Engineering (Hands-On)
- Design, build, and evolve AWS Landing Zone capabilities using IaC and automation (e.g., Terraform/CDK/CloudFormation + CI/CD).
- Implement and maintain multi-account patterns, baseline configurations, and secure-by-default guardrails (SCPs, IAM standards, encryption/KMS, centralized logging, config rules, detective controls).
- Publish and maintain reference architectures and reusable patterns for common workloads (networking, segmentation, endpoints, logging, monitoring, shared services).
- Compliance Enablement & Evidence
- Ensure AWS platform capabilities support required control objectives (e.g., NIST 800-171-aligned requirements and other program-driven frameworks).
- Build audit-ready evidence through automated checks, standard configurations, and repeatable artifacts (control mappings, test results, runbooks).
- Operational Excellence & SOC/SIEM Integration
- Own AWS operational health: SLOs, incident processes, change controls, patching/upgrades, and service reliability.
- Enable enterprise security monitoring: standardized logs, alerting, and integrations that support corporate SOC and SIEM workflows.
- Sub-Contractor Management
- Direct and manage sub-contractor daily work: backlog assignment, priorities, acceptance criteria, QA, documentation, and knowledge transfer.
- Establish SLAs, escalation pathways, and a continuous improvement cycle for support quality and platform stability.
- Customer Obsession & UX for Engineers
- Treat GDMS programs/internal teams as customers: capture pain points, remove friction, improve "time-to-first-workload."
- Improve platform usability: clear docs, onboarding checklists, templates, paved roads, and developer-friendly guardrails.
Requirements
- AWS Certified Solutions Architect (Associate or Professional) - required
- 7+ years in IT platform, cloud, or infrastructure roles with 3+ years in AWS at scale.
