Job Category: Applied R&DDegree Level: Bachelor's degreeJob Description:Join a high-performance engineering group working at the forefront of application identification and DDoS mitigation technologies. This role offers a challenging environment where you will analyze complex network behaviors, build automated test systems, and help strengthen technologies protecting global networks.Responsibilities:

Contribute to the design, validation, and continuous improvement of application identification algorithms and DDoS mitigation technologies.
Verify and analyze application detection mechanisms along with network behaviors involving QUIC, HTTPS, RTP and other protocols.
Develop automated test cases in a Linux-based regression environment to validate application signatures and new DDoS mitigation features.
Set up and configure test servers/services (e.g., HTTP servers, DNS servers) to create realistic test environments.
Work collaboratively with testers and developers to identify, analyze, report, and resolve software defects.
Monitor and debug automated regression systems, improving test coverage and tool capabilities.
Break down complex problems piece by piece, diving deep into traffic flows, signatures, packet behavior, and system interactions.
