KEY RESPONSIBILITIES
|
- Design and develop High-Level Design (HLD) and Low-Level Design (LLD) documents for OT cybersecurity infrastructure.
- Perform OT Cybersecurity Gap assessment , risk assessments as per IEC 62443 , NIST and international standards .
- Perform cable routing and physical installation of network and security devices in substations and control centers.
Engineering Design (HLD/LLD) & Drawing Development
- Review and validate Single Line Diagrams (SLDs), existing as-built drawings, and brownfield constraints; raise RFIs and propose constructible solutions.
- Validate panel drawings (GA, internal layout, wiring, interconnection, termination schedules, BOM) and ensure “as-built” updates post commissioning.
- OT Cybersecurity Infrastructure Deployment & Integration
- Implement and integrate OT cyber infrastructure components (e.g., industrial firewalls, switches, IDS sensors, secure remote access, logging collectors) according to approved LLD and standards.
- Support network cutovers, IP schemes, VLAN/VRF mapping, routing design inputs, and secure connectivity between substations and central platforms.
- Ensure installations meet required security baselines and customer utility practices (documentation, labeling, ports, hardening inputs).
Testing, FAT/SAT, Commissioning & Acceptance
- Support/lead FAT preparation and execution: test procedures, inspection checklists, configuration verification, and evidence packs.
- Execute SAT / site commissioning, including pre-checks, power-up, connectivity validation, link testing, redundancy checks, punch lists/snags, and final handover.
- Coordinate with OEMs and customer operations for outage windows, access approvals, and acceptance criteria signoffs.
