About The Position

We are seeking a Senior IT Platform Specialist to act as the AWS Platform Owner within DIGITALcore responsible for the vision, roadmap, and hands-on delivery of the AWS Secure Landing Zone and associated AWS-native platform capabilities. You will operate the AWS environment as an internal product, enabling GDMS programs and internal services to onboard quickly, build securely, and meet compliance requirements. You will manage feature development and platform evolution, while also managing our sub-contractor providing day-to-day operational support. The ideal candidate combines deep AWS platform and infrastructure expertise with strong service ownership instincts customer obsession, user experience awareness, and the ability to translate stakeholder needs into secure, scalable platform features.

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.
Strong experience with AWS Organizations/multi-account design, IAM/federation, networking (VPC, routing, endpoints), security services (CloudTrail/Config/Security Hub/GuardDuty), encryption/KMS, and IaC automation.
Proven ability to lead delivery through cross-functional teams and/or managed service partners.

Nice To Haves

AWS Solutions Architect Professional and/or AWS Security Specialty.
Experience with IT service ownership, platform lifecycle management, or service delivery models.
Experience with landing zone frameworks (Control Tower and/or custom) in regulated environments.
Product management fluency (roadmaps, requirements, metrics, prioritization tradeoffs).
Experience integrating cloud telemetry into enterprise SOC/SIEM operations.

Responsibilities

Own the AWS platform roadmap inside DIGITALcore: define priorities, epics, and release plans for the Landing Zone and AWS platform services.
Establish AWS platform “product” outcomes: onboarding velocity, reliability, security posture, and customer satisfaction.
Align AWS platform priorities with DIGITALcore system governance, enterprise architecture, and security/compliance stakeholders.
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).
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).
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.
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.
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.
