Security Engineer

Security Engineer About us: Indurex is an AI-native, engineering-first company focused on keeping complex cyber-physical systems resilient, safe, and secure. Our platform unifies safety, process, and cybersecurity data to deliver context-aware, AI-scored incidents and actionable recommendations - complementing existing SCADA/DCS, historians, and security tools. With headquarters in Amsterdam, Indurex partners with regional and global energy, manufacturing, utilities, data center, and pipeline operators to safeguard the systems that power and connect our world. We are building the first OT cybersecurity platform with decision logic. We need someone who thinks like an attacker and can turn that thinking into labelled datasets, pcaps, logs, suricata rules, and detection logic. This role sits at the heart of the product: the attacks you simulate become the ground truth our ML models and agents are trained and tested against. The Suricata rules you write become the baseline detection layer beneath our agents. The PCAPs you capture prove our verification specs and model real threats not theoretical ones. You will closely work with software, AI/ML, security, and domain experts. Your responsibilities will include: Attack simulation Simulate realistic attack scenarios against IT and OT environments, such as lateral movement, command injection, protocol replay, man-in-the-middle across OT protocols PCAP and log capture Capture, label, and organize PCAPs and structured logs from each scenario to build the ground-truth dataset used by detection models and agent evaluation Suricata rules Write, test, and tune Suricata detection rules against your own attack traffic — own the feedback loop Lab infrastructure Build and maintain the attack simulation lab, on-prem hardware and cloud environments, keeping both clean, reproducible, and version-controlled
