Department manager within Hydraulics and Injection Development
At MAN Energy Solutions, we are committed to tackling the big challenges posed by climate change. Our mission, “Moving Big Things To Zero,” drives us to develop and provide cutting-edge technology for the maritime sector. Our goal is to enable global shipping to run on carbon-neutral fuels derived from renewable energy sources, such as methanol and ammonia. If you share our passion for decarbonizing the shipping industry, the position of Head of Hydraulic Prototype Testing at MAN Energy Solutions R&D in Copenhagen could be the perfect fit for you.

  • Foster professional growth and development for every team member.
  • Expect 20-40 travel days per year, primarily to our licenses in Japan and South Korea.
  • Since the Danish Headquarter of MAN Energy Solutions will move office, production and testing facilities within 5 years, the build up from scratch of a new hydraulic and injection test center will be part of your responsibility.


  • Leadership experience, preferably in the shipping or industrial sector and related to physical testing of mechanical or mechatronic systems.
  • You see planning as an essential part of the job, both technically and in terms of managing test activities.
  • International experience, ideally involving collaboration with partners in China, South Korea, and/or Japan.
