Wärtsilä Energy Storage & Optimization (ES&O) is the leading global energy storage optimizer. Our mission is to deliver integrated energy solutions that build a resilient, intelligent, and flexible energy infrastructure - unlocking the way to an optimized renewable future. By integrating renewables, energy management technology, and storage with traditional energy resources, we reinvent clean energy production from the largest and most complex grids to the most remote and essential microgrids. We play a key role in Wärtsilä's vision towards a 100% renewable energy future through flexibility, reliability, and integration and a more sustainable world for us all.

We are seeking a Power Systems Intern to join our growing software team. The primary function of this role is to advance the development of our electrical and power systems modeling tools. The Power Systems Intern is expected to show solid theoretical background in dynamic modeling of inverter-based resources and power systems. The intern will mainly focus on dynamic modeling of battery energy storage systems (BESS) in PSCAD or similar software tools and the grid-code and stability analysis of BESS + solar PV systems. The candidate should have strong hands-on experience using PSS/E and EMT tools such as PSCAD for dynamic modeling and simulation. Prior practical experience with modeling inverter-based resources is a must-have. The Intern will be an integral part of the Simulation and Data Science team in a Research and Development role, working to accelerate the development of our software capabilities while supporting new product development initiatives in the field of automated power system optimization.

The primary location for this position is Herndon, VA.
