We're seeking an IoT/OT Network Engineer to build and maintain secure, reliable connectivity infrastructure for our global Vegetable R&D sites. You'll enable digital transformation by designing robust IoT/OT network architectures, integrating industrial systems with corporate IT, and supporting smart agriculture initiatives through secure connectivity and data-driven automation.
This role accelerates R&D digitization by enabling real-time data capture, reducing manual processes, and ensuring seamless integration between field sensors, industrial systems, and cloud platforms鈥攗ltimately driving operational efficiency and faster innovation cycles.
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.
