Job Analysis:

This Senior Software Engineer role on the Network Security team at ByteDance is fundamentally centered on safeguarding the company’s cloud platforms from Distributed Denial of Service (DDoS) attacks, specifically focusing on Layers 4 and 7 of the network stack. The core objective is to develop robust DDoS protection strategies and build operational defense platforms that ensure both stability and resilience of the Volcano Engine and BytePlus cloud environments. This involves not only deep technical expertise in TCP/IP protocols, DDoS attack vectors, and defense mechanisms, but also engineering skill to create scalable and efficient solutions under pressure. The responsibility extends to innovation by exploring modern technologies like Large Language Models (LLMs) to anticipate and mitigate evolving cyber threats. Success in this role means delivering reliable, proactive defense systems that maintain uptime and trust for ByteDance’s diverse, large-scale online ecosystem. The candidate must excel in cross-disciplinary collaboration across engineering, operations, and security teams, managing ambiguity in threat landscapes and responding rapidly to incidents. Strong programming skills in C/C++, Python, or Go enable hands-on system development and troubleshooting. Customer focus and systematic problem-solving capabilities indicate that the role entails defending not only technical infrastructure but also upholding user experience and business continuity. Experience with cloud-based DDoS protection is highly valuable, suggesting a strategic preference for candidates who understand cloud environments at a systems level. The engineer will regularly make decisions on prioritizing mitigation strategies and tradeoffs between performance and security, often under stressful conditions, requiring excellent judgment and resilience. Performance in the initial 6-12 months likely revolves around demonstrating technical ownership of DDoS defense features, improving operational efficiency of attack detection, and contributing innovative ideas leveraging emerging tech to enhance protection.
