Security Engineer - Network Edge Security

The Role

The Network Edge Security team builds the tools that provide important insights to our API Security posture and trustworthiness of traffic flowing into our systems. Our capabilities use machine learning, streaming analytics, and significant data analysis to provide insights into understanding our network edge risk exposure and the true sources of our request flows.

However, there is also a need at times to respond quickly to emerging threats to take action at the edge to provide immediate relief. The team is small, requiring nimbleness and flexibility to stay ahead of threat actors.

• Evaluate and build integrations with vendor systems that may be used in addition to in-house solutions
• Develop and implement AI-driven capabilities to automatically classify and mitigate abusive traffic patterns
• Significant experience with bot/fraud identification and mitigation systems is a strong plus
