  • Advanced experience operating within a SAFe Agile environment in a large government organization
  • Enhanced expertise in cloud security, identity-driven access, and network transformation strategies

Typical Day:

A typical day entails operating within a SAFe Agile environment, starting with a brief daily stand-up to align on priorities, provide updates, and identify blockers. Team communication and coordination are primarily conducted through Microsoft tools and Jira, with work tracked via assigned tickets and sprint boards.

Work is executed in two-week sprint cycles, focusing on prioritized stories and features defined by leadership. In parallel, the role supports ongoing Operations & Maintenance (O&M) activities, including service ticket resolution, vulnerability management, and system sustainment to ensure operational stability.

Tasks:

• Participate in SAFe Agile ceremonies (daily stand-ups, sprint planning, retrospectives) and deliver work within sprint cycles
• Lead the implementation of Zscaler ZIA and ZPA to support Zero Trust and cloud-delivered security objectives
• Develop and execute migration strategies to transition from legacy forward proxies and VPNs to Zscaler-based architectures
• Design direct-to-cloud connectivity solutions that eliminate on-premises traffic backhaul
• Configure and optimize Zscaler policies (URL filtering, SSL inspection, DLP, access controls) to meet security requirements
• Integrate Zscaler with enterprise identity providers (e.g., Active Directory, Azure AD) to enforce identity-based access
• Collaborate with cross-functional teams (network, security, cloud) to support Zero Trust and TIC 3.0-aligned architectures
• Manage and resolve complex network security issues, including traffic flow, access, and policy enforcement troubleshooting
• Support Operations & Maintenance (O&M) activities such as service ticket resolution, vulnerability remediation, and system sustainment
• Develop and maintain technical documentation, including architecture diagrams, implementation…
