Job description

Join WW Technic, where engineering expertise meets purpose.

Do you know 2-stroke marine engines inside out, from the crankshaft to the exhaust valve?

Do you enjoy finding the root cause of a problem and bringing a vessel back to full performance?

At WW Technic, you will be part of a team that combines engineering mastery with the mission of making industries more efficient, reliable and sustainable.

About WW Technic

WW Technic is an engineering services company providing technical expertise in shipbuilding, ship repair, offshore, oil & gas, and the power & heat sectors.

Our work goes beyond technology. It’s about trust, precision and partnership.

About The Role

As a Service Engineer / Service Superintendent, you will take care of the large 2-stroke diesel engines that power sea-going vessels around the world. When an engine needs an inspection, a repair or a modification, or a difficult technical question needs a clear answer, the crew and the client will turn to you.

You will work on both conventional and electronically controlled engines. You will also take part in modifications that help vessels meet today’s efficiency and emission requirements.

You Will

• Carry out engine inspections, including scavenge port inspections, measurements and condition assessments
• Perform and supervise overhauls of key components, such as pistons, cylinder liners, exhaust valves, fuel injection equipment and bearings

Working environment

Our service engineers work worldwide, on board sea-going vessels, in ports and at repair yards.

Assignments usually last 2 weeks, adding up to around 6-7 months per year on-site.

Service work sometimes comes at short notice, so flexibility is part of the job.

Between assignments, you remain on stand-by at home, fully paid and supported, with time to rest, prepare and stay close to your family & friends.

Every assignment connects you with project teams that provide guidance, technical expertise and real-time support. You will never be left alone, even when the engine room presents its toughest challenges.

At WW Technic, knowledge is shared, not owned. Our engineers support each other, ensuring continuous improvement and safety across every project.

• Readiness to travel worldwide for 2 weeks assignments, 6-7 months per year in total

It Will Be An Advantage If You Have

• Sea-going experience as a marine engineer (e.g. 2nd Engineer)
• Experience with electronically controlled engines
• Experience with dual-fuel engines or emission and efficiency retrofits
• Experience in supervising repair teams or coordinating dry dock work

We Will Also Value

• Strong communication and interpersonal skills
• A goal-oriented, self-driven and result-focused attitude
• Ability to work both independently and as part of a team
• Entrepreneurial mindset and good organizational skills

What We Offer

• Stable, long-term cooperation based on a full-time employment contract

• Work-life rhythm that respects your time, with paid stand-by periods between assignments
• Challenging tasks on a wide variety of vessels and engine types
• Continuous professional development through technical training and mentoring, and real opportunities for promotion
• A friendly team culture built on trust, expertise and collaboration, where your work matters and your knowledge grows

Why WW Technic

Because we know what it means to be an engineer.

We understand the satisfaction of tracking down a fault that nobody else could find, the pressure of a tight schedule in port, and the pride of seeing a vessel sail on with its engine running smoothly.

We also know how important it is to have support, stability, and recognition for your expertise.

At WW Technic, we build long-term relationships with clients and with our people. Join us, and bring your experience to a company that values reliability, skill and respect in every project.
