• Manage and monitor environment performance and proactively identify optimization opportunities to enhance efficiency, scalability, reliability, and security.
• Design, build and secure VPNs, VPC peering, transit gateways, private endpoints, and hybrid network solutions (on-prem to cloud).
• Configure and manage cloud-native firewalls (e.g., AWS Network Firewall, Azure Firewall) and route tables to ensure traffic segmentation and control.
• Design and implement zero trust architecture (ZTA) strategies, including identity-aware proxies, microsegmentation, and secure service mesh deployments.
• Implement, configure, and optimize cloud-native and third-party threat detection tools (e.g., IDS/IPS, NDR, VPC flow logs, GuardDuty, Azure Defender) to monitor for malicious activity, misconfigurations, and anomalous behavior across cloud environments.
• Automate network and security provisioning using tools like Terraform, Ansible, or CloudFormation.
• Identify and remediate risks associated with network exposure, misconfiguration, and insecure cloud services.
• Implement and manage security groups, NACLs, and security policies aligned with corporate standards and compliance frameworks.
• Support investigation and response to cloud-based network threats and incidents.
• Participate in change management process including development of change management plans for production upgrades.
• Work closely with CloudOps, DevOps, and Security Engineering teams to ensure secure deployment pipelines and cloud service configurations.

• 8 years of experience in network security engineering, including at least 3 years focused on cloud environments.
• Expert-level knowledge of network protocols, security controls, segmentation strategies, and VPN technologies.
• Proven experience with cloud networking (VPCs, subnets, NAT, routing, peering) in AWS, Azure, or GCP.
• Proven experience with next-generation firewalls, cloud-native security groups, NACLs, and traffic filtering.
• Solid understanding of Zero Trust models, defense-in-depth, and layered security strategies.
• Proficiency with infrastructure-as-code tools and scripting (e.g., Terraform, Python, Bash).
• Familiarity with security standards and regulatory frameworks (NIST, CIS, ISO 27001, SOC 2).
• Strong research, technical writing, and documentation skills.
• Excellent interpersonal communication skills
• Must be legally authorized to work in the United States without Company sponsorship now and in the future.
  
  

Ideal Qualifications

• Experience designing and architecting cloud and hybrid environments
• Experience in securing Kubernetes, service mesh (e.g., Istio), and container networking.
• Knowledge of SD-WAN or SASE architecture.
• Background in enterprise-scale hybrid or multi-cloud deployments.
• Experience with cloud-native logging and monitoring (e.g., GuardDuty, CloudTrail, Azure Monitor, VPC flow logs).
• Certifications such as:
• Azure Network Engineer Associate
• CISSP, CCNP Security, or equivalent experience
