Key Accountabilities

Network Architecture Security & IT/OT Integration

• Develop and maintain IoT/OT network architectures with dedicated IIoT VLANs layered firewalls NAT and application proxies aligned with ISA/IEC 62443 NIST CSF and zero-trust principles.
• Implement secure connections between Vegetable R&D sites and corporate networks with robust IT/OT boundary protection.
• Manage certificate lifecycle device authentication encryption and SBOM/supply-chain controls for firmware and edge devices.

Industrial Systems & Hardware Integration

• Integrate sensors PLCs SCADA/DCS historians and industrial data loggers with secure northbound flows and store-and-forward buffering.
• Configure firmware edge devices/gateways and PLC programming for reliable data acquisition and seamless system connectivity.
• Identify and implement appropriate sensors electronics and hardware to digitize manual R&D processes.

Cloud Edge & Remote Management

• Design IoT solutions using AWS IoT Core Greengrass SiteWise and Device Defender with secure Direct Connect/VPN connectivity.
• Implement edge reliability through QoS buffering OTA updates and secure remote protocols for firmware/configuration management.
• Architect industrial time synchronization (IEEE 1588 PTP/NTP) and manage latency/determinism for control networks.

Operations Monitoring & Change Management

• Maintain OT asset inventory (passive discovery) validate patches/firmware and enforce backup/restore for PLC/SCADA configurations.
• Deploy passive OT monitoring (TAP/SPAN) establish ICS-specific incident response playbooks and coordinate with enterprise SOC.
• Execute formal management of change (MOC) with production windows rollback procedures and runbooks to avoid process disruptions.
• Drive adoption of secure networking and digitization practices across global Vegetable R&D sites.
