Company Description
White Knight Labs is a specialized offensive cybersecurity consultancy focused on high-impact security assessments and advanced training.

Role Description
The OT/ICS Security Consultant role is a remote position responsible for assessing and improving the security posture of operational technology (OT) and industrial control system (ICS) environments. Day-to-day tasks include conducting security assessments and penetration tests for OT/ICS networks, identifying vulnerabilities in industrial systems and applications, and simulating attacker techniques relevant to critical infrastructure. The consultant collaborates with client engineering and security teams to develop practical remediation strategies, create clear technical and executive-ready reports, and provide guidance on secure architecture and controls for OT and ICS. Additional responsibilities may include contributing to internal methodologies, participating in red team exercises, and supporting training content related to industrial cybersecurity.

• Hands-on experience with OT/ICS technologies (PLC, SCADA, DCS, HMI) and common industrial protocols (Modbus, DNP3, OPC, etc.) is highly beneficial.
• Relevant certifications (e.g., GICSP, GRID, OSCP, CISSP, or equivalent) and experience in offensive security or red teaming are advantageous.
• Strong analytical and written communication skills, ability to work independently in a remote setting, and a collaborative mindset for working with multidisciplinary teams are essential.
