• Automate simulation schedules and workflows to evaluate system sensitivities more efficiently.

• Evaluate how new generation, battery storage, transmission projects, and large electrical loads influence future energy prices.
• Support the development of standardized reporting for impact studies and modeling results.

• Partner with engineers, analysts, and stakeholders to improve model quality and analytical processes.
• Present findings and technical insights in a clear and meaningful way to both technical and non-technical audiences.

• Pursuing a Bachelor's degree in Electrical Engineering (Power/Energy Systems) or Operations Research.
• Candidates pursuing a Master's degree are strongly encouraged to apply.
• Coursework focused on power systems, optimal power flow, production cost modeling, or energy markets is preferred.

• Experience programming in at least one language such as Python or R.
• Strong analytical and problem-solving abilities.
• Interest in power system modeling, optimization, or energy market analysis.

• PLEXOS
• Dayzer
• PSS®E
• PowerWorld
• PSCAD
• Electric utility internships
• Power system analysis or planning
• Energy market modeling

We're looking for someone who is:

• Naturally curious and eager to learn.
• Analytical with strong attention to detail.
• Comfortable taking ownership of projects from start to finish.
• Able to balance independent work with collaboration.
• An effective communicator who can explain technical concepts clearly.
