  • Monitor and respond to security events in cloud environments (e.g., AWS, GCP, Azure, Datacenter), with emphasis on network traffic analysis
BASIC QUALIFICATIONS:
  • Bachelor's degree in computer science, cybersecurity, information systems, or a science discipline
  • 5+ years of experience in network security engineering, with hands-on focus on switching and routing
PREFERRED SKILLS AND EXPERIENCE:
  • Proficiency in at least one major cloud platform (AWS, GCP, or Azure) and its network security services (e.g., VPCs, Security Groups)
  • Experience with network analysis tools such as Wireshark, tcpdump; and vendors including Cisco, Juniper, Palo Alto Networks
  • Familiarity with scripting languages (e.g., Python, Bash) for automation of network security tasks
  • Relevant network-specific certifications (e.g., CCNP Security, CCIE Security, JNCIP-SEC, PCNSE)
  • Certifications such as CISA, CRISC, CGEIT, Security+, CASP+ preferred
  • Experience in multi-cloud environments and Infrastructure as Code tools like Terraform for network provisioning
  • Knowledge of DevSecOps practices tailored to network security integration
  • Experience building custom tools or integrations for enhancing network security operations
  • Interest in leveraging AI for network threat detection and automation
  • Contributions to open-source projects in network security or related tools
  • Strong understanding of network security principles, protocols (e.g., TCP/IP, VLANs, ACLs), and best practices for secure routing and switching
COMPENSATION AND BENEFITS:
