Senior Cloud Architect

Overview

LMI seeks an experienced Senior Cloud Architect to lead cloud architecture design, implementation, and sustainment for the U.S. Army Center for Initial Military Training's (CIMT) Holistic Health & Fitness (H2F) management System. This environment supports a vendor-developed application and includes Army cloud hosting, cybersecurity, continuous ATO (cATO) compliance, DevSecOps enablement, data ingestion, and a custom user interface.

The Senior Cloud Architect will design secure, scalable cloud solutions in an Army-approved cloud environment (AWS, Azure, or cARMY), ensuring compliance with DoW and Army cybersecurity policies. This role includes ownership of system architecture, network configuration, identity/access implementation, logging/monitoring, and cloud service integration. The architect will collaborate closely with cybersecurity engineers, DevSecOps engineers, data engineers, full stack developers, and the TPM to deliver a resilient, secure, and maintainable cloud platform. This is a senior technical leadership role requiring deep experience in DoW cloud environments, RMF/cATO, Zero Trust architecture, and cloud-native modernization.

• Define data storage, encryption, retention, tagging, and access-layer architecture.
• Ensure the environment supports dashboards, analytics tools, and data products required by Human Performance specialists.
• Architect monitoring, logging, alerting, and observability systems (CloudWatch, Azure Monitor, ELK, Grafana, etc.).
• Define and implement backup/restore, failover, BC/DR, and environment hardening strategies.
• Support environment troubleshooting, incident response, and performance tuning.
• Provide senior-level technical leadership across a cross-functional Agile team.
• Mentor junior cloud engineers and guide architectural decision-making.
• Participate in sprint planning, technical backlog refinement, and architecture reviews.
