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 - Deep understanding of plant operations and constraints - Ability to design practical, deployable solutions - Strong problem-solving in constrained environments - Cross-domain communication (engineering, IT, digital) 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%).
