Key Responsibilities:

  • DDoS Attack Mitigation: Detect, analyze, and mitigate DDoS attacks in real-time, ensuring minimal impact on network services.
  • Network Traffic Analysis: Monitor network traffic to identify unusual patterns or potential DDoS threats, use deep packet inspection (DPI) and traffic profiling to differentiate between legitimate and malicious traffic, and collaborate with the network team to develop network visibility tools for enhanced threat detection.
  • Infrastructure Design & Optimization: Design and optimize network infrastructure to be resilient against DDoS attacks, collaborate with the IT and network engineering teams to integrate DDoS protection solutions into the existing infrastructure, and recommend improvements for scalability, redundancy, and fault tolerance in the network architecture.
  • Automation & Monitoring: Automate DDoS mitigation responses using custom scripts and orchestration tools, set up and maintain monitoring tools (e.g., Grafana, Kibana, SolarWinds) to track key performance metrics and attack trends, and continuously update and fine-tune monitoring systems to quickly detect and address any anomalies.
  • Collaboration & Training: Work closely with network engineers, security teams, and system administrators to align on best practices for network security and DDoS prevention, provide technical guidance and training to junior engineers on DDoS attack vectors and mitigation techniques, maintain comprehensive documentation of network security policies, procedures, and incident reports, and perform regular vulnerability assessments of the network infrastructure and recommend proactive security measures.

Requirements:

  • Bachelor's degree in Computer Science, Information Technology, Network Engineering, or related field (or equivalent experience).
  • 3+ years of experience in network engineering with a focus on security and DDoS mitigation.
  • Proven track record of handling large-scale network infrastructures and mitigating DDoS attacks in production environments.
  • Strong knowledge of TCP/IP, BGP, DNS, HTTP/HTTPS, and other key networking protocols.
  • Proficient in network diagnostic tools (Wireshark, tcpdump, NetFlow, etc.).
  • Hands-on experience with firewalls, load balancers, VPNs, and other network security appliances.
  • Scripting skills (Python, Bash, or PowerShell) to automate mitigation and monitoring tasks.

Desired Skills:

  • Experience with cloud DDoS protection solutions (AWS Shield, Azure DDoS Protection, etc.).
  • Familiarity with SIEM solutions and integration of network security tools.

Salary: $100,000
