Job description

The Opportunity

Join our HVDC R&D team at Hitachi Energy and help pioneer the future of energy transmission. We are now looking for a R&D Engineer to be involved in the development of 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.

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 continuous improvements in control strategies. Additionally, you will support strategic technology roadmaps, helping shape the future direction of HVDC control systems and power electronics design.

How You Will Make an Impact

• 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 performances 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.

Your Background

• PhD or MSc (with some years of experience) in Power Systems, Electrical Machines and Drives, or Power Electronics Control.
• Preferred if you have some years of 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.

What we offer

• Collective agreement
• Flexible working time
• Health care and wellness allowance
• Fantastic career possibilities within Hitachi Energy both within Sweden and globally
• Mentor to support you throughout onboard phase
• Various trainings and education supporting employee development
• Diversified company with over 70+ nationalities working in Sweden
• Supplementary compensation for parental leave
• Employee Benefit Portal with thousands of discounts and perks
