Position Overview

The Principal Edge & OT Architect is responsible for designing and governing the edge architecture and OT integration layer that connects manufacturing systems to the digital platform. 

This role ensures: 

• Reliable and secure data ingestion from plant systems 
• Consistent implementation of the semantic model at the edge 
• Support for real-time AI inference and decision-making 

This role ensures that what is designed in the cloud can actually work in the plant. 

Job Responsibilities

1. Define Edge Architecture and Runtime 

Design edge platform including: 

• Runtime environments (containers, orchestration) 
• Deployment models (on-prem, hybrid) 

Define integration with enterprise edge platforms and ensure scalability across multiple sites. 

2. Integrate OT Systems (Technical Integration) 

Own the technical connectivity and protocol-level integration with OT systems: 

• Define integration patterns for PLCs, DCS, SCADA systems, historians, and industrial data sources 
• Support protocols such as OPC-UA, Modbus, and MQTT 
• Ensure compatibility with existing plant infrastructure 

Note: Semantic translation and data modeling for OT data are governed by the Principal Manufacturing & Semantic Architect. 

3. Enforce Semantic Model at the Edge 

Ensure data is: 

• Normalized 
• Validated 
• Aligned with canonical definitions before leaving the plant 

Prevent "garbage-in" at scale. 

4. Enable Edge-Based AI Inference 

Design architecture to support: 

• Local model execution 
• Real-time decision-making 

Ensure: 

• Low latency 
• High reliability 
• Offline capability 

5. Design for Security and Compliance 

Implement: 

• Secure communication (outbound-only patterns) 
• Device identity and authentication 
• Certificate management 

Align with enterprise security standards. 

6. Support Deployment and Lifecycle Management 

Define: 

• Edge deployment processes 
• Update mechanisms 
• Version control for edge components 

Ensure maintainability across sites and customers. 

7. Collaborate Across Teams 

Partner with: 

• Principal Manufacturing & Semantic Architect (canonical model enforcement at the edge) 
• Principal Industrial AI Data Architect (data pipeline integration and edge inference data requirements) 
• Platform Engineering (cloud-to-edge deployment and orchestration) 
• Plant Operations teams (site-specific requirements and constraints) 

Ensure consistent execution across domains. 

Key Competencies

Minimum Qualifications

• Bachelor's degree in Engineering — Electrical, Computer, Chemical, Industrial, or related field (Master's preferred) 
• 10+ years of experience in OT systems, industrial automation, or edge/IoT architectures 
• Strong experience with PLC/DCS/SCADA systems and industrial protocols (OPC-UA, Modbus, MQTT) 
• Experience with edge-enabled inference model deployment 
• Experience integrating OT with IT/cloud platforms 

Preferred Qualifications

• Experience with: 
• Enterprise edge platforms (e.g., Dell NativeEdge, Azure IoT Edge, AWS IoT Greengrass) 
• Containerized environments (Docker, Kubernetes) 
• Cloud platforms (AWS preferred) 
• Familiarity with: 
• Cybersecurity in OT environments 
• Real-time systems and constraints 

Leadership Expectations

• Operate as a thought leader in edge architecture and OT integration 
• Influence without direct authority across multiple teams and partners 
• Drive standards adoption for edge deployment and OT connectivity across internal and external stakeholders 
• Balance long-term architectural vision with near-term delivery needs 

Work Environment & Travel

Travel to manufacturing sites and partner locations as needed (~10–25%).
