Major duties and responsibilities

ECMA cARMY onboarding

• Run the ECMA intake end to end:
o tenant request package and account vending
o Control Tower / Landing Zone Accelerator guardrails within the ECMA baseline
o IAM Identity Center federation to the Army identity provider
o VPN and boundary connectivity requests
• Prepare and track the Government artifacts the program depends on: the Authorizing Official designation memo, the ISSO appointment and the inherited-control matrix.
• Use established working relationships with ECMA, the Authorizing Official and SCA-V to keep reviews moving.
• Maintain a dependency tracker for every Government-paced item, with owner, submission date and escalation path, reported weekly.
• SIPR option: repeat onboarding for IL6, covering the second Authorizing Official chain, SIPR identity binding, the DISA SIPRNet circuit request and classified break-glass access.
Landing zone and environments
• Deliver reusable, parameterized landing-zone infrastructure code for cARMY: account baseline, service control policies, centralized CloudTrail/Config/log archive, Security Hub, GuardDuty, network baseline with VPC endpoints, and the KMS key hierarchy. NIPR and SIPR must differ only by parameters.
• Stand up NIPR development, test and staging by about month 4, and multi-region production by about month 7. Production includes Global Tables and Route 53 failover, with recovery time and recovery point objectives documented and demonstrated.
• Integrate with the program's AWS SAM application layer through a defined contract: exported VPC, subnet, endpoint, KMS and logging identifiers. The engagement does not fork or replace the application templates.
IL5 boundary, STIG and ATO acceleration
• Define the IL5 authorization boundary: boundary and data-flow diagrams, ports, protocols and services, and the split of inherited, shared and system-specific controls with cARMY.
• Deliver NIST SP 800-53 Rev. 5 conformance packs and DISA STIG automation for Lambda, API Gateway, DynamoDB and the landing-zone services, with evidence the RMF team can load into eMASS.
• Provide System Security Plan templates pre-filled for cARMY-inherited controls, and support the SSP amendment, eMASS submission and SCA-V coordination.
• Set up DoD PKI certificate distribution and rotation.
Continuous ATO
• Provide the continuous-ATO playbook and help stand up the OSCAL/ConMon pipeline: Config and Security Hub feeds, drift detection, the ConMon dashboard and the 30-day evidence period.
• Support the Authorizing Official signature campaign toward NIPR continuous ATO at month 12.
Migration into cARMY
• Plan and execute the move of the demonstrator from the commercial GovCloud account into cARMY: AWS DMS or DynamoDB export and import, cut-over and rollback runbooks, and a full rehearsal. Workloads land in development, test and staging first, then production.
Knowledge transfer and exit
• Pair with the Lead DevSecOps / SRE throughout. Every artifact is committed to the program repositories, runs through the program pipeline, and is operated at least once by program staff before month 9.
• Deliver runbooks and architecture decision records for every landing-zone design decision.

Required

• ECMA cARMY onboarding experience: has taken at least one prior Army tenant through ECMA cARMY onboarding to first authenticated deployment. This is the qualification that defines the role.
• GovCloud landing zones at IL5: Control Tower and/or Landing Zone Accelerator, AWS Organizations and service control policies, IAM Identity Center, centralized logging, Security Hub, GuardDuty, AWS Config conformance packs.
• DoD authorization: DoD Cloud Computing SRG, RMF, NIST SP 800-53 Rev. 5 and eMASS, with direct experience of Authorizing Official and SCA-V review cycles. Prior continuous-ATO or ConMon delivery is strongly preferred.
• Infrastructure as code: production-quality CloudFormation / AWS SAM. CDK (Landing Zone Accelerator) or Terraform is acceptable where the output integrates with the SAM application layer.
• Serverless platform depth: Lambda, API Gateway, DynamoDB (Global Tables, point-in-time recovery, Streams, capacity), EventBridge, SQS, KMS, WAF, VPC endpoints, Route 53 failover.
• Data migration: AWS DMS and DynamoDB export and import.
• Hardening: DISA STIG automation for cloud and serverless resources.
• Experience and education: 10+ years in cloud infrastructure, including 5+ years in AWS GovCloud or DoD environments. Bachelor's in IT, CS or a related field, or equivalent experience.

Certifications

• AWS Certified SysOps Administrator – Associate or higher is required. This is the labor-category minimum and cannot be waived.
• AWS Certified Solutions Architect – Professional is expected for this engagement.
• AWS Certified Security – Specialty or DevOps Engineer – Professional is preferred.
• The engineer must be DoD 8140 compliant for the IAT/IAM functions performed.

Preferred

• Prior SIPR/IL6 (AWS Secret Region) enclave build-out and DISA SIPRNet circuit coordination
• Army Cross-Domain Solution (ARCDS) familiarity, if cross-domain capability enters scope
• OSCAL tooling and Security Hub-to-eMASS evidence automation
• GovCloud FinOps, tagging and cost-allocation design
• Comfort working with an AI-augmented team. Generated infrastructure code and STIG scripts are welcome once reviewed to an ATO-defensible standard.
