Cyber Security Engineer

We are seeking an experienced OT (Operational Technology) Cybersecurity Solutions Specialist to design, implement, and propose security architectures for industrial control systems (ICS), SCADA, and critical infrastructure. The ideal candidate will have deep expertise in OT security frameworks, industrial protocols, network security, and compliance standards, along with strong documentation and proposal-writing skills.

Key Responsibilities

OT Security Architecture Design

Design high-level and low-level OT security architectures for industrial networks (DMZ segmentation, Purdue Model, Zero Trust).

Develop secure network topologies integrating Next-Generation Firewalls (NGFW), IDS / IPS, SIEM, and Active Directory (MS AD).

Ensure secure integration of industrial protocols (Modbus, DNP3, OPC UA, PROFINET).

Prepare technical proposals, RFP responses, and solution presentations for clients.

Create detailed security policies, risk assessments, and architecture diagrams.

Maintain OT cybersecurity standards documentation aligned with IEC 62443, NIST SP 800-82, NERC CIP.

Security Implementation & Advisory

Recommend and deploy OT security solutions (firewalls, NAC, endpoint protection, PAM).

Conduct OT network security assessments (vulnerability scanning, penetration testing).

Advise clients on best practices for securing ICs / SCADA environments.

Required Qualifications

2-3 years in OT / ICS cybersecurity (not just IT security).

Hands-on experience in designing OT security architectures.

Strong knowledge of industrial protocols (Modbus, DNP3, OPC UA, PROFIBUS).

Experience in writing proposals, technical documents, and compliance reports.

Familiarity with NGFW, IDS / IPS, network segmentation, and MS AD integration.

Understanding of IEC 62443, NIST CSF, NERC CIP, and other OT security standards.

Certification in Industrial Cybersecurity Frameworks, Technologies and procedures.
