R&D Senior Engineer – DC Link Capacitor Technology

We are recruiting on behalf of a global technology leader in the energy sector, located in Ludvika, Sweden. The company develops world-leading high-voltage direct current (HVDC) solutions that enable efficient and reliable transmission of electricity across long distances.

About the Role

As an R&D Senior Engineer in the HVDC Valve Development team, you will be at the forefront of designing next-generation converter valves. Your focus will be on DC link capacitor technology, which plays a key role in ensuring the reliability, efficiency, and safety of HVDC transmission systems.

This position is research- and development-oriented and does not involve manufacturing. Instead, you will take responsibility for design, analysis, validation, and testing, while working cross-functionally with experts in mechanical design, insulation, controls, and system engineering. Approximately 20% travel is included, both within Europe and internationally.

Key responsibilities include:

• Lead the design and integration of capacitors within HVDC converter valves.
• Perform design calculations, circuit simulations, and stress analysis on electrical components.
• Specify, select, and qualify high-voltage capacitors for power electronics applications.
• Plan and participate in validation and reliability testing in laboratory environments.
• Write and review technical requirements, specifications, test plans, and reports.
• Conduct workshops and gather knowledge to build deep expertise on capacitor components.
• Collaborate with international colleagues and external partners, including capacitor suppliers and research teams.
• Contribute to R&D initiatives and design reviews to shape the next generation of HVDC valves.
• Document and present results to stakeholders internally and externally.

Candidate Profile

We are looking for a candidate with a strong academic background and the ability to work independently, proactively, and innovatively. You should have both depth in capacitor technology and the capacity to take a holistic view of HVDC systems.

Requirements:

• PhD in Electrical Engineering, Power Engineering, or a closely related field.
• A Master’s degree with extensive and highly relevant industrial experience may also be considered.
• Proven expertise in capacitor technology for HVDC or power electronics.
• Solid understanding of power electronic converter technologies.
• Experience with dielectric materials and passive components in high-voltage environments.
• Background in validation, reliability engineering, or testing is desirable.
• Excellent communication skills and ability to collaborate in cross-functional teams.
• Proactive, innovative, and solution-oriented mindset with a system-level perspective.
• Fluency in English, both spoken and written.
