Description Leidos is seeking a Cloud Security Architect to lead the design and development of secure multi-cloud solutions supporting the U.S. Air Force Cloud One Next (C1N) ACSS contract.In this role, you will serve as a senior technical architect responsible for designing security capabilities across Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI). The Cloud Security Architect will translate mission, cybersecurity, and platform requirements into implementable architectures and work directly with engineering teams to turn those architectures into reusable Cloud One capabilities.This is a solution architecture and engineering-focused role, rather than a security operations or compliance management position. The architect will evaluate technologies, develop reference architectures, prototype solutions, make technical recommendations, define integration patterns, and guide engineering teams through implementation.The Cloud Security Architect will work across cloud, network, platform, DevSecOps, and cybersecurity teams to determine how security capabilities should be designed and integrated into the Cloud One platform. A primary objective of the role is to abstract CSP-specific security complexity into standardized architectures and reusable capabilities that can be consistently deployed across Cloud One environments.Key Responsibilities:Multi-Cloud Security Architecture: Design security architectures and solutions spanning AWS, Azure, GCP, and OCI, identifying common architectural patterns while accounting for CSP-specific capabilities and limitations.Security Solution Development: Translate cybersecurity requirements and identified capability gaps into implementable technical solutions, including architecture, technology selection, integration patterns, and implementation guidance.Reference Architecture Development: Create reusable reference architectures, design patterns, technical standards, and archi
