• 5+ years of experience in enterprise network engineering with significant cloud networking exposure
• Demonstrated expertise with AWS networking services (VPC, Transit Gateway, Direct Connect, Route 53, AWS Network Firewall)
• Experience implementing and managing Zscaler solutions (ZIA, ZPA, ZDX)
• Strong knowledge of VoIP/UC technologies and protocols (SIP, RTP) in cloud environments
• Hands-on experience with network automation and Infrastructure as Code (Terraform, CloudFormation)
• Relevant certifications preferred: AWS Certified Advanced Networking, Zscaler Certified Professional, CCNP/CCIE
• Experience with SD-WAN solutions and their integration with cloud security platforms
• Excellent problem-solving skills and ability to work effectively in a global team environment 

(Nice-to-Have) Qualifications

• Knowledge of compliance requirements for network security (SOC2, ISO27001, GDPR)
• Hands-on experience with network observability tools like ThousandEyes, AppDynamics, or Datadog

• Scripting skills in Python, Bash, or PowerShell for network automation
•  Exposure to GitOps workflows for network infrastructure management
• Previous work with global WAN optimization technologies
• Experience with WebRTC and real-time communications protocols

What will make you stand out!

• Direct aerospace or defense industry experience - Previous work in organizations like Lockheed Martin, Boeing, SpaceX, Northrop Grumman, or similar would be highly valuable due to understanding of the unique industry challenges.
• Demonstrated compliance implementation - Specific examples of implementing ITAR, NIST 800-171, or CMMC controls in AWS environments, rather than just general awareness.
• AWS GovCloud experience - Specific work history building and managing AWS GovCloud environments, as these operate differently from standard AWS regions.
• Multi-account architecture design - Experience designing and implementing secure AWS Organizations structures with separate accounts for production/development/security.
