Job description

Overview

Join our HVDC R&D team at Hitachi Energy and help pioneer the future of energy transmission. We are looking for an R&D Engineer to develop advanced control strategies for HVDC systems, including Modular Multilevel Converter (MMC) and Line Commutated Converter (LCC) technologies. This is a unique opportunity to work 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 part of your responsibilities will be to contribute to system-level dynamic performance evaluations and ongoing improvements in control strategies. Additionally, you will support strategic technology roadmaps, helping shape the future direction of HVDC control systems and power electronics design.

• Contribute to converter topology design, control and protection, insulation coordination, and main circuit development for VSC HVDC and LCC HVDC systems.
• Conduct steady‑state, transient, and dynamic stability studies, harmonic analysis, and performance evaluations 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

• Ph.D. or M.Sc. (with some experience) in Power Systems, Electrical Machines and Drives, or Power Electronics Control.
• Preferred experience in HVDC or FACTS technologies.
• Strong knowledge of MMC topologies and HVDC control systems.
• Proven expertise in small‑signal stability analysis and transient simulations.
• Skilled in simulation tools: MATLAB, PSCAD/EMTDC, EMTP‑RV, and ideally Modelica, Dymola, RTDS, Python, C/C++.
• Open‑minded, solution‑oriented, and collaborative with strong organizational skills.
• Proficiency in English is required.

Benefits

• Collective agreement
• Flexible working time
• Health care and wellness allowance
• Fantastic career possibilities within Hitachi Energy globally
• Mentor support during onboarding
• Various training and education opportunities for employee development
• Diverse company with over 70 nationalities in Sweden
• Supplementary compensation for parental leave
