Job description

Hitachi Energy’s Grid Automation business is looking for an Application Engineer to develop software applications used by electrical utilities to monitor, study, optimize, control, and simulate power networks, smart grid systems, and distributed energy resources. In this role, you will work on highly available, scalable, and reliable power systems software that supports transmission and distribution networks relied on every day. You will design, develop, test, review, and maintain applications that help utility operators improve grid reliability, evaluate system conditions, and support real‑time operational needs. This role offers the opportunity to apply software development skills alongside power systems knowledge, working across areas such as EMS applications, power system modeling, simulation, optimization, numerical methods, and data standards. Your work will contribute to the future of grid automation by helping create tools that support a more resilient, intelligent, and innovative power grid.

How You’ll Make an Impact

• Design, develop, test, review, and maintain power systems applications with quality and reliability in mind.
• Build software applications that support electrical utility operations, smart grid capabilities, and distributed energy resource use cases.
• Collaborate with team members on planning, development, and testing to meet agreed “definition of done” criteria.
• Apply power system studies, modeling, simulation, optimization, and numerical methods to application development.
• Support EMS-related applications such as load flow, contingency evaluation, state estimation, operator training simulators, and power system simulators.
• Identify technical issues, schedule risks, and quality concerns, then work with the team to resolve them.
• Contribute to retrospectives, reflection, and steady incremental improvement across the software development process.
• Work across Linux and Windows development environments using relevant programming languages and tools.
• Responsible to ensure compliance with applicable external and internal regulations, procedures, and guidelines.
