at HITACHI ENERGY

🏢 About HITACHI ENERGY

Hitachi Energy is a global leader in advancing sustainable energy systems, playing a critical role in the transition to a carbon-neutral future. Working here means contributing to cutting-edge network management technology that powers reliable energy infrastructure worldwide. The company's commitment to innovation and sustainability makes it an inspiring place for engineers who want to make a tangible impact on the planet.

About This Role

This internship focuses on developing high-quality software for Hitachi Energy's Network Management System (FOXMAN-UN), a product that manages wired networks for energy utilities. You'll be part of an international, interdisciplinary team designing and implementing features that ensure reliable network operations. Your work will directly support the stability of energy grids, making this role both technically challenging and socially meaningful.

💡 A Day in the Life

You'll start with a daily stand-up meeting with your agile team to discuss progress and blockers. The rest of the day involves coding new features for the FOXMAN-UN system—perhaps implementing a dashboard widget or optimizing a backend service—followed by code reviews and testing. You'll collaborate with network engineers and product managers to refine requirements, and end the day by documenting your work or exploring new technologies relevant to the project.
