Job description

Opportunity

Join our HVDC R&D team at Hitachi Energy and help pioneer the future of energy transmission. We are looking for a senior R&D engineer to contribute to the development of advanced control strategies for HVDC systems, including Modular Multilevel Converter (MMC) and Line Commutated Converter (LCC) technologies. This unique opportunity is in a global, collaborative environment focused on innovation and technical excellence.

Responsibilities

In this role, you will design and optimize control algorithms for MMC‑ and LCC‑based HVDC systems, including multiterminal HVDC (MTDC) configurations. You will also perform small‑signal stability analysis, harmonic studies, and transient simulations to ensure robust and reliable system performance. A key part of your responsibilities will be to lead system‑level dynamic performance evaluations and drive continuous improvements in control strategies. Additionally, you will mentor junior engineers and actively contribute to strategic technology roadmaps, shaping the future direction of HVDC control systems and power electronics design.

Contribute to converter topology design, control and protection, and main circuit development for VSC HVDC and LCC HVDC systems.
Perform insulation coordination, steady‑state and dynamic stability studies, harmonic analysis, and performance tests under various conditions.
Address evolving customer requirements with a strong stakeholder focus.
Uphold our core values of safety, integrity, and responsibility.
Collaborate in a supportive and agile team environment.
Take ownership of both technology and your personal development.

Qualifications

PhD or MSc in Power Systems, Electrical Machines and Drives, or Power Electronics Control.
Several years of experience in HVDC or FACTS technologies.
Strong knowledge of MMC topologies and HVDC control systems.
Experience in small‑signal stability analysis and transient simulations.
Skilled in simulation tools: MATLAB, PSCAD/EMTDC, EMTP‑RV, and ideally Modelica, RTDS, Python, C/C++.
Open‑minded, solution‑oriented, and collaborative with strong organizational skills.
Proficiency in English is required.
