Reporting to the Director of Information Security, this role executes Aspira's security strategy by delivering resilient, scalable, and compliant cloud networking solutions, while providing Tier 3 technical depth to the broader security and operations teams. This role translates security strategy into practical, operationalized cloud and network controls.

Key Responsibilities

Cloud & Hybrid Networking

  • Design and implement secure connectivity across AWS VPCs, Transit Gateway, ExpressRoute, and Direct Connect, in alignment with policies and standards defined by the Director of Information Security.
  • Support hybrid integration of Dallas and China office networks with AWS workloads through site-to-site VPNs, IPSec tunnels, and Direct Connect.
  • Enforce segmentation strategies (subnets, VLANs, security groups, NACLs) using AWS Network Firewall for cloud workloads and Palo Alto / Cisco ASA for on-prem environments, aligned with zero-trust principles.

Network Security

  • Configure and manage next-gen firewalls (Palo Alto Panorama, Cisco ASA / Meraki, Fortinet) across cloud and on-prem environments.
  • Deploy and operate AWS-native firewall / security controls (AWS Network Firewall, WAF, Shield).
  • Implement and tune intrusion detection, DDoS mitigation, and endpoint-aware access policies under guidance from the Director.
  • Ensure all logs, flows, and firewall telemetry are ingested into SIEM platforms (Rapid7, LogRhythm, Splunk) as required by security governance.

    • Monitoring, Incident Response & Compliance

  • Utilize AWS CloudWatch, CloudTrail, GuardDuty, and Security Hub for visibility and detection.
  • Tune and maintain security alerts for anomalies, IAM misconfigurations, and suspicious traffic.
  • Act as Tier 3 escalation point for complex network / security incidents, reporting incident summaries and remediation outcomes back to the Director of Information Security.
  • Provide technical evidence and reporting to support audits, insurer requirements, and customer security reviews.
  • Support compliance frameworks (NIST, PCI, SOC 2, CIS benchmarks) with security controls and operational evidence.
  • Contribute to security KPIs, including SIEM coverage across assets, MTTR for incidents, and SLA compliance for patching.

    • Automation & Infrastructure as Code

  • Build and manage Infrastructure as Code (Terraform, Ansible, CloudFormation) for secure, repeatable deployments.
  • Embed automated security controls into CI / CD pipelines under direction of the Director's security roadmap.
  • Continuously optimize cost and performance of cloud networking through automated enforcement of routing, peering, and inspection policies.

    • Collaboration & Team Support

  • Partner with DevOps, IT Ops, and AppSec teams to integrate secure networking into projects and migrations.
  • Mentor junior engineers and analysts, aligning daily practices with security policies and standards.
  • Provide architecture recommendations to the Director of Information Security and contribute input during design reviews.

    • Qualifications

  • 7-10 years in network engineering, with at least 4+ years in cloud networking / security.
  • Deep technical knowledge of AWS (VPC, Transit Gateway, Direct Connect, GuardDuty, Security Hub).
  • Hands-on experience with Palo Alto (Panorama), Cisco ASA / Meraki, and Fortinet firewalls.
  • Strong understanding of routing (BGP, OSPF), load balancing, and hybrid troubleshooting.
  • Proficiency in automation / scripting (Terraform, Ansible, Python, Bash, CloudFormation).
  • Familiarity with compliance standards (NIST 800-53, PCI DSS, SOC2, CIS).
  • Preferred certifications : AWS Security Specialty, AWS Advanced Networking Specialty, PCNSE, CCNP Security.
