Cloud Architect​/Engineer in Washington

Job Summary

Leidos is seeking a highly skilled Cloud Architect / Engineer to design, implement, optimize, and maintain enterprise cloud infrastructure across multiple platforms. The role focuses on ensuring high availability, security, performance, scalability, and cost‑efficiency of ATR’s cloud environments, collaborating with cross‑functional teams to support business growth and drive cloud adoption.

• Drive the enterprise technology vision by defining long‑term strategic blueprints and engineering standards supporting the implementation of cloud technologies such as Generative AI applications, production‑ready RAG pipelines, scalable vector database indexing, clustering and retrieval pipelines to optimize vector search, scalable GPU/TPU compute clusters, managed container services, automated auto‑scaling for LLM workloads, private cloud networks, secure API gateways, and dedicated endpoints to isolate AI traffic from the public internet, and applications leveraging modern microservices and APIs.
• Design and implement scalable, secure, and resilient hybrid cloud architectures using cloud‑agnostic tools and processes.
• Architect and manage core cloud networking components (VPCs, VNets, subnets, transit gateways/peering, firewalls, private links, Direct Connect/Express Route, etc.).
• Implement Infrastructure as Code (IaC) using tools such as Terraform, Cloud Formation, Bicep, ARM, and Ansible to automate provisioning and configuration management.
• Implement comprehensive cloud security controls, compliance frameworks (SOC 2, ISO 27001, HIPAA, PCI‑DSS, CMMC, etc.), encryption, security groups, WAF, and monitoring for threats and misconfigurations.
• Develop and implement processes to optimize cost and utilization through resource tagging, rightsizing, reserved instances/savings plans, and continuous cost analysis.
• Set up and maintain monitoring, logging, and observability solutions using tools like Cloud Watch, Azure Monitor, Google Operations, Datadog, Prometheus/Grafana, or ELK stack.
• Support disaster recovery, high availability, and business continuity strategies, including backup/restore, failover architectures, and regular DR testing.
• Collaborate with Network, Security, Application Development, and Operations teams on cloud‑related projects, incident response, and architecture reviews.

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field and 12+ years of relevant experience, or Masters degree with 10+ years of relevant experience. Additional years of experience will be considered in lieu of a degree.
• 12+ years of progressive experience in cloud architecture, engineering, and operations, with at least 4 years in a senior or lead Cloud Architect role.
• Strong experience designing and implementing hybrid/multi‑cloud environments (AWS, Azure, Google Cloud) at enterprise scale.
• Proven expertise with Generative AI infrastructure, including production‑ready Retrieval‑Augmented (RAG) pipelines, scalable vector databases (e.g., Pinecone, Weaviate, Milvus, FAISS, or managed services) with indexing, clustering, and optimized retrieval, GPU/TPU compute clusters, managed container orchestration (Kubernetes/EKS/AKS/GKE), and auto‑scaling for large model (LLM) workloads.
• Deep hands‑on experience with Infrastructure as Code (IaC) tools:
  Terraform, AWS Cloud Formation, Azure Bicep/ARM, and Ansible.
• Strong background in cloud networking: VPCs, VNets, subnets, transit gateways, peering, private links, Direct Connect/Express Route, firewalls, security groups, WAF, and private API gateways.
• Demonstrated experience implementing enterprise security and compliance frameworks (SOC 2, ISO 27001, HIPAA, PCI‑DSS, CMMC, FedRAMP, etc.), including encryption, threat monitoring, and zero‑trust architectures.
• Experience with observability and monitoring stacks (Cloud Watch, Azure Monitor, Google Operations, Datadog, Prometheus/Grafana, ELK/EFK stack).
• Proven track record in cost optimization (tagging, rightsizing, Reserved Instances, Savings Plans) and disaster recovery/business continuity planning.
• Excellent collaboration and communication skills; ability to…
