• Responsible for designing and developing AI-based automated security detection tools, enabling automated alert triage, attack attribution, and improved security operations efficiency.

• Participate in building Agent behavior auditing and anomaly detection systems, identifying abnormal behavior chains during Agent runtime, constructing an AI-driven security operations platform, and exploring, designing, and implementing defense and countermeasure solutions based on real business scenarios.

• Combine security risks of cloud-native infrastructure (K8S, Docker, cloud services) to assess the attack surface of Agent runtime environments and design defense-in-depth solutions.

Requirements:

• At least 3+ years of security offense/defense experience (penetration testing/red team practice), with 1+ years of experience in LLM (large model) security offense/defense; extensive hands-on red team experience preferred.

• Familiar with network architecture and cloud-native technology stacks, including K8S, Docker container security, and cloud security (IAM, network isolation, cloud-native threat models, etc.), with the ability to assess security risks in complex infrastructure.

• Possess practical Agent development capability, able to independently build/modify AI Agents (e.g., based on frameworks such as LangChain), as well as hands-on offensive capability against Agents (practical construction and validation of attack techniques such as tool misuse, prompt injection, context poisoning).

• Familiar with security frameworks such as OWASP Top 10 for LLM and MITRE ATT&CK, familiar with common AI attack techniques, adversarial logic, and defense solutions, with a strong passion for AI security.

• Proficient in at least one programming language such as Python/Go/C++, with the ability to develop security offense/defense tools or perform deep secondary development on open-source security platforms.

Nice to Have

• Familiar with mainstream AI frameworks (PyTorch, TensorFlow, LangChain, etc.), with practical experience in local deployment and optimization of large language models.

• Hands-on cloud security (AWS) experience or related certifications.
