要約求人票をもとにAIがまとめたものです

Lead detection engineering for Cyber Defense Operations, building Detection-as-Code pipelines and AI/LLM-driven detection capabilities. The role includes implementing eBPF-based runtime monitoring, threat hunting and attack simulations, deception technologies, and integrating detection logic with SOAR.

応募資格

必須

  • Experience: 10+ years in Cyber Security, with at least 5+ years in Detection Engineering or Security Research.
  • Detection Engineering: Deep expertise in building detection pipelines, tuning logic for high-fidelity alerts, and managing the security rule lifecycle.
  • AI/ML/LLM Proficiency: Practical experience building/tuning models for anomaly detection and log analysis.
  • Technical Depth: Expert-level coding skills (Python, Go, or Rust) and mastery of Linux/Windows/Mac internals.
  • Container & K8s Security: Strong hands-on experience securing Kubernetes clusters, container runtimes, and microservices architectures.
  • Domain Knowledge: Understanding of Telco networks/protocols (e.g., 5G core, signaling) and Network Security (packet analysis, perimeter/internal controls).
  • Offensive Mindset: Experience in penetration testing, exploit development, or red teaming.
  • Education: Bachelor's or Master's degree in Computer Science, Cyber Security, or equivalent.
  • Certifications: Relevant certifications (e.g., OSCP, GREM, GCFA, CKS, BTL2, or AI-Security credentials).
  • English (Overall - 3 - Advanced)

歓迎

  • Experience with Infrastructure as Code (Terraform, Ansible, Crossplane).
  • Deep experience with eBPF tools (e.g., Tetragon, Falco, Cilium, Spyderbat).
  • Active contributor to open-source detection projects (e.g., Sigma, YARA, or custom AI-detection models).
  • Experience in high-scale environments (Telco, Cloud-Native, or FinTech).

仕事内容

Job Duties

Detection-as-Code (DaC) Transformation: Build and manage an end-to-end detection pipeline featuring peer reviews, version control (Git), and a reusable repository of detection rules.

AI/LLM-Driven Detection: Architect and develop AI/LLM-based models to identify autonomous AI attacks. Use AI to automate log onboarding, normalize data, and filter "garbage logs" to drastically reduce SOC noise.

Advanced Runtime Security: Lead the implementation of kernel-level monitoring using eBPF-based tools to provide deep visibility into containerized (K8s) and Linux-based workloads.

Offensive Security & Threat Hunting: Perform continuous attack simulations (Red Teaming) to validate detection coverage. Lead proactive threat hunting initiatives informed by CTI and the MITRE ATT&CK/FIGHT frameworks.

Deception & Defense-in-Depth: Deploy and manage deception technologies to create high-interaction traps. Ensure detection logic aligns with our defense-in-depth architecture.

Cross-Functional Orchestration: Collaborate with DFIR, CTI, and SOC teams to ensure CTI is actively integrated into detection logic via AI-driven automation.

AI Guardrails & Security: Oversee the security of our own AI/LLM models, implementing guardrails to prevent model poisoning, prompt injection, and adversarial manipulation.

SOAR Integration: Partner with the SOC team to ensure detection logic feeds seamlessly into SOAR playbooks for machine-speed response.

Work Environment

Department: Detection Engineering Section, Cyber Defense Operations.

Collaboration: Work with diverse teams including security researchers, threat hunters, and AI/ML specialists.

Tech Stack: Python/Go/Rust, Kubernetes, Linux, eBPF, Git/Sigma/YARA, LLM-integrated pipelines, SOAR, Terraform/Ansible.
