About the role

Key responsibilities & impact

Support the design and maintain landing zones using cloud applications such as AWS Organizations, Control Tower, SCP guardrails, Identity and Access Management (IAM) multi-account patterns, and VPC architectures (Transit Gateway, PrivateLink, NAT, IGW) for enclave isolation and cross-domain needs.
Engineer high-availability, multi-Region solutions leveraging cloud tools such as EC2, EKS/ECS Fargate, RDS/Aurora, DynamoDB, S3/EFS/FSx, Load Balancers, Route 53, and API Gateway.
Implement Zero Trust-aligned patterns (micro-segmentation, strong identity, continuous verification) consistent with DoD Zero Trust guidance.
Implement security controls and evidence generation for RMF ATO packages (SSP, SAR, POA&M) in coordination with cybersecurity teams.
Apply DISA STIGs (OS, DB, Kubernetes, Container) and SRG requirements for workloads at IL2–IL6.
Tailor and automate STIG application using IaC and configuration management.
Integrate encryption and key management with cloud tools such as AWS KMS/HSM; enforce IAM least privilege, SCPs, permission boundaries, ABAC, and robust secrets management.
Implement cloud logging and metrics tools such as CloudTrail/CloudWatch/GuardDuty/Config for comprehensive audit and detection.
Align architectures with FedRAMP Moderate/High baselines when required and ensure boundary compliance for controlled workloads.
Develop secure connectivity (AWS Direct Connect/VPN), hybrid routing, and segmentation; implement TLS mutual auth, certificate management, and private service endpoints.
Design logging and telemetry pipelines (CloudWatch, OpenTelemetry, Kinesis, S3, SIEM integration such as Splunk/ELK) with retention, metadata/tagging, and data lifecycle policies.
Own SLOs/SLAs for platform services.
Implement autoscaling, health checks, and proactive capacity management.
Lead cost management and alerting practices of cloud environments in coordination with project leads.
Provide Tier 3 support, on-call rotations during exercises, and incident response coordination with cybersecurity and training operations.
Collaborate with agile teams and product owners to translate training requirements into platform capabilities.
Provide mentorship for junior engineers.
Establish standards, design reviews, and repeatable processes.
Present cloud solutions to project leadership and accreditation authorities.
