The driving force behind our success has always been the people of AspenTech. What drives us, is our aspiration, our desire and ambition to keep pushing the envelope, overcoming any hurdle, challenging the status quo to continually find a better way. You will experience these qualities of passion, pride and aspiration in many ways — from a rich set of career development programs to support of community service projects to social events that foster fun and relationship building across our global community.

The Role

As a Sr. Principal Power Systems Model Engineer at Emerson-AspenTech Digital Grid Management (DGM), you will lead technical engagements with utility customers to implement, customize, and support power system modeling solutions using Emerson-Aspen Tech’s NMM (Monarch) platform. You will serve as the primary modeling authority, guiding clients in developing high-fidelity transmission models and ensuring successful integration into planning and operational environments. Deep expertise in transmission system modeling, CGMES CIM Standards (15, 16, and 17), and end-to-end model configuration and testing will be essential to delivering high-quality solutions, resolving complex challenges, and driving product adoption.

Your Impact

• Serve as the lead modeling expert supporting utility clients in building, configuring, and maintaining accurate transmission network models using Monarch NMM.
• Apply thorough knowledge of CGMES CIM Standards 15, 16, and 17, ensuring proper interpretation, compliance, and implementation in transmission model workflows.
• Deliver end-to-end modeling solutions, including data onboarding, model configuration, validation, and integration with EMS, SCADA, GIS, OT/IT systems, and planning tools.
• Perform hands-on model setup, including topology configuration, parameter validation, connectivity checks, and functional testing to ensure model accuracy and reliability.
• Customize integration and data-quality workflows to meet client-specific requirements.
• Diagnose and resolve technical and modeling issues, coordinating with internal development and support teams to ensure timely resolution.
• Conduct client training sessions, workshops, and develop user documentation to build modeling competency.
• Mentor client engineering teams on model development practices, data governance, CGMES exchanges, and simulation workflows.
• Translate client feedback into actionable recommendations to support product enhancements.
• Collaborate closely with R&D to improve automation, data ingestion, CGMES handling, and usability features.
• Contribute to the development of advanced scripts, tools, and validation processes to streamline model building and quality assurance.
• Provide technical expertise to support sales engagements, customer success initiatives, and proposal development.
• Maintain up-to-date knowledge of transmission modeling methodologies, regulatory requirements, CIM/CGMES standards, and emerging modeling technologies.

What You'll Need

• Bachelor degree in electrical engineering with a focus on Power Systems.
• 15+ years of experience in transmission system modeling, ideally in a consulting or client-facing capacity.
• Proficiency with Monarch NMM or comparable power system modeling platforms.
• Strong knowledge of utility modeling workflows, CGMES CIM Standards (15/16/17), and industry-standard analysis tools (e.g., PSS®E, PSLF, PowerWorld).
• Demonstrated experience in end-to-end model configuration, setup, validation, and testing.
•  Excellent communication, presentation, and leadership skills.
• Master’s degree in electrical engineering with a focus on Power Systems preferred.
