Leidos is an industry and technology leader serving government and commercial customers with smarter, more efficient digital and mission innovations. The Cybersecurity and Cloud Automation Engineer will support AWS, Azure, Google, and Oracle clouds, focusing on securing and automating cloud environments to enhance system resiliency and security.

Responsibilities:

• Implement and maintain security controls for AWS services, aligned with NIST, FISMA, and DISA STIG requirements
• Configure secure logging, monitoring, and telemetry (e.g., CloudTrail, CloudWatch, SIEM integrations) for cloud workloads
• Perform vulnerability scanning, assessment, and coordination of remediation across cloud hosts, containers, and services
• Contribute to security architecture reviews and change/configuration boards to ensure secure designs and deployments
• Develop, maintain, and version-control IaC modules (e.g., Terraform, CloudFormation) for AWS networking, compute, storage, IAM, and security resources
• Use CaC tools (e.g., Ansible, Puppet) to automate OS, middleware, and application configuration and hardening
• Build and support CI/CD pipelines that integrate IaC/CaC and security checks for automated build, test, and deployment
• Create and maintain hardened, STIG/CIS-aligned golden images and reusable templates for repeatable secure deployments
• Encode security baselines, IAM policies, network segmentation, and encryption standards into IaC/CaC and pipeline code (Security-as-Code)
• Integrate automated security and compliance testing (SAST/DAST, dependency scanning, policy-as-code) into pipelines to enforce controls before release
• Support continuous monitoring and ATO/continuous authorization by maintaining evidence, automated checks, and documentation for audits
• Support day-to-day operation of multi-environment AWS landscapes (dev/test/stage/prod/DR), including monitoring health and performance
• Troubleshoot issues across networking, access, and application deployment; contribute to incident and problem management and root cause analysis
• Implement and maintain identity- and context-aware access controls, MFA, and policy-based access in line with Zero Trust strategies
• Collaborate with developers, cloud engineers, security analysts, and operations staff to design secure, automated solutions
• Contribute to technical documentation, including architecture diagrams, IaC/CaC module references, SOPs, and runbooks
• Share best practices in secure cloud engineering and automation with teammates; provide informal knowledge transfer and peer support (no direct reports)

Requirements:

• Bachelor's degree in a technical field with 8 years of applicable experience, additional years of experience in cloud and cybersecurity engineering will be accepted in lieu of a degree
• Hands-on experience with AWS cloud services and DevSecOps practices in production environments
• Practical experience with IaC/CaC tools (e.g., Terraform/CloudFormation and Ansible/Puppet) and CI/CD pipelines
• Experience applying NIST, FISMA, and STIG/CIS controls in cloud environments and supporting ATO/accreditation activities
• Strong written and verbal communication skills and ability to work effectively in cross-functional teams
• AWS certifications (e.g., Solutions Architect, Security Specialty) or security certifications such as CISSP, CISM, or CAP
• Familiarity with Zero Trust architectures, SASE/ZTNA solutions, and ICAM integrations
• US DoW Secret clearance
• Access to SIPR Facility
