About The Position

Enterprise Strategy & Architecture (ES&A) is a centralized architecture organization within the Information Technology department. ES&A supports the company’s safety, reliability, affordability, and regulatory objectives by providing clear architectural direction, disciplined governance, and practical guidance that accelerates delivery while reducing risk and complexity. Reporting to the Senior Manager Technology Architecture, this role serves as the Enterprise Architect for Operational Technology. The role owns architecture direction for facilities systems, sensors, field telemetry, control systems, and edge environments across substations, field sites, and other operational locations. The successful candidate is a systems‑level thinker and master planner who translates enterprise strategy into living target architectures, prioritized roadmaps, and reusable patterns, working early and continuously with delivery and operations teams to ensure solutions are aligned, secure, and executable. Architects in this role are expected to focus on enabling outcomes and delivery.

Requirements

BA/BS in Computer Science, Engineering, Business, or related field, or equivalent experience

Architecture certification such as TOGAF or equivalent practical experience

Responsibilities

Define and evolve target architecture for Operational Technologies and shared services, providing a clear north star that guides investment, design, and modernization decisions
Translate enterprise and IT strategy into capability‑based roadmaps, identifying maturity gaps, dependencies, and sequencing required to move from current to target state
Own architecture outcomes across a portfolio of Operational Technologies, ensuring alignment from strategy through implementation and operations
Define and govern the enterprise OT, facilities, sensor, and field telemetry architecture strategy across operational environments, including data centers, field sites, substations, control centers, critical facilities, and edge locations.
Architect sensor-to-platform and real-time telemetry patterns, including instrumentation standards, data collection, buffering, streaming, time-series data, alarm/event architecture, operational monitoring, and facilities/industrial observability.
Define IT/OT integration architecture across operational systems, facilities platforms, field devices, control systems, and enterprise technology environments, ensuring interoperability, supportability, and clear segmentation boundaries.
Architect OT cybersecurity, resiliency, and critical infrastructure protection patterns, including IT/OT segmentation, secure connectivity, operational continuity, disaster recovery, safety, regulatory, and critical infrastructure compliance requirements.
Lead architecture for edge and field computing environments, including compute at substations, plants, remote sites, control centers, and critical facilities, while ensuring solutions are resilient, observable, operationally supportable, and aligned to business continuity needs.
Engage early in planning and solution shaping, helping teams align on architecture direction, integration patterns, and non‑functional requirements before major commitments are made
Enable delivery teams through reusable architecture patterns, standards, reference architectures, and decision frameworks
Support architecture reviews and working sessions to surface risks, manage dependencies, and validate solution direction
Guide teams when deviations are required, managing trade‑offs and technical debt while maintaining enterprise coherence
Ensure architecture standards are current, practical, and consistently applied, focusing on reuse and simplification
Support IT strategic planning, modernization, and platform consolidation efforts
Coordinate roadmaps across infrastructure, security, application, data, and operations teams to manage interdependencies and conflicts
Lead or support vendor evaluations, platform selections, and RFP activities
Contribute to technology rationalization by reducing redundancy and improving platform consistency
Partner closely with business and IT leaders to align architecture with operational realities and strategic priorities
Collaborate across architecture disciplines to ensure enterprise‑wide consistency and integration
Coach and mentor engineers and architects, promoting strong architectural discipline and shared accountability
Use metrics and feedback loops to monitor progress, measure adherence to target architecture, and continuously improve architecture practices
