Principal Specialist – Hydraulics and Injection Development

Experienced Technical Leader for Advanced Development Projects

Are you motivated by the opportunity to lead cutting-edge engineering projects that contribute to a more sustainable future? At Everllence, we are proud to be a global leader in maritime propulsion technology, designing advanced two-stroke engines for large ocean-going vessels. Our innovations play a vital role in the decarbonization of the shipping industry, enabling the transition to carbon-neutral fuels such as methanol and ammonia.

Our engines rely on highly dynamic and powerful hydraulic systems to drive fuel injection and valve actuation. As we continue to push the boundaries of engine design, we also develop new hydraulic and injection components to meet the demands of next-generation propulsion systems.

If you thrive in a fast-paced, collaborative development environment and share our commitment to sustainable innovation, the role of Principal Research Engineer in our Hydraulics and Injection Development team in Copenhagen may be the perfect opportunity for you.

Your Role and Responsibilities

In this position, you will take on a central technical decision making role, guiding the development of hydraulic and fuel injection systems for our future engine platforms. Your key responsibilities will include:

• Serving as the technical lead in development projects focused on hydraulic systems and fuel injection technologies.
• Driving development activities within the line organization and supporting formal cross-functional projects in collaboration with colleagues across R&D and Engineering.
• With direct contact to 2-stroke management supporting technical and strategic decision-making with analysis and investigations.
• Sharing your expertise and insights proactively, both within your immediate team and with stakeholders across the wider organization, to foster continuous learning and innovation and become the to-go person within the team for technical matters.

Your Background and Qualifications

We believe you will thrive in this role if you bring:

• A degree in a relevant engineering discipline (e.g. Mechanical Engineering, Marine Engineering, Hydraulics, Mechatronics, Combustion Engines) and at least 5 years of professional experience in related fields.
• A strong track record of leading complex technical projects, preferably within the combustion engine or the maritime sector. Experience in R&D environments is a distinct advantage.
• International collaboration experience, ideally involving partners in China, South Korea, and/or Japan.
• Skilled in communicating professionally within all layers of a modern organization, including high level management.
• Excellent interpersonal skills and the ability to build and maintain trust-based relationships with a diverse range of stakeholders.
• A collaborative mindset and the ability to understand technical challenges within the broader context of product development and organizational strategy.

Meet Your Team: Hydraulics and Injection Development

You will join the management team within our Hydraulics and Injection Development function, part of Everllence's two-stroke R&D division. Our team is responsible for:

• Designing fuel injection and hydraulic actuation systems for both on-engine and off-engine mechatronic applications.
• Conducting structural and thermal analyses, transient hydraulic simulations, and CFD modeling of fuel injection, combustion, and emissions.
• Running rigorous testing programs on hydraulic rigs and full-scale engines—both experimental and finalized designs—on test beds and in operational service.

We foster a relaxed and supportive working atmosphere, where creativity is encouraged and collaboration is key. You'll find space to explore new ideas and contribute meaningfully to the development of future technologies.
