Your role and responsibilities

As a (Senior) Technical Expert, you will work with technical queries from end customers.

Your knowledge during commissioning with auxiliary fuel components (for example - pumps, filters, separators, pressure regulators, flow metering, injectors) will be drawn on to provide internal support. Experience working with integrator shipyard fuel system partners and their technology would also be advantageous.

Your diagnostic skills and ability to tackle complex challenges will be vital in ensuring the smooth operation of our systems and upholding our high standards of performance.

As a Senior Technical Expert, you will focus on these responsibilities :

• Serve as the system expert for liquid fuel feed systems, including methanol and dual-fuel configurations.
• Lead root cause analysis and troubleshooting for complex fuel-related issues both in the field and remotely.
• Collaborate with automation, component, and field service teams to resolve technical challenges and improve system performance.
• Provide technical guidance and documentation for internal stakeholders, shipyards, and customers.
• Support commissioning and start-up activities, including on-site coordination and remote diagnostics.
• Conducting site surveys and troubleshooting in the field for more interesting cases.
• Contribute to the development of new fuel system technologies and participate in R&D and product improvement initiatives with suppliers.
• Act as a mentor and knowledge resource for junior engineers and technical specialists.

Preferred qualifications and experience :

• BSc or MSc in Mechanical Engineering or similar education.
• Experience of auxiliary systems in the field.
• A basic understanding of mass and heat balances.
• A genuine passion for engines, related auxiliaries and a desire to make a difference.
