We are seeking an experienced In-Situ Service Engineer to join our Field Service team in Hamburg. You will carry out machining, repair and alignment work at customer sites around the world, helping minimise downtime and keep marine engines and other critical equipment operating reliably.

What you’ll be doing

You will perform and coordinate on-site machining and repair work, from initial inspection through to completion. Working on Wärtsilä and other OEM equipment, you’ll provide practical technical support to customers and collaborate with colleagues and other stakeholders to deliver safe, high-quality work on schedule.

Your responsibilities will include:

- Assessing damage, wear and misalignment in engine and other marine components, such as crankshafts, engine blocks, cylinder liners, bearing pockets and propeller shafts.

- Performing specialist work including line boring, crankshaft machining and grinding, milling, flange facing, cylinder boring and honing, metal stitching and laser alignment.

- Troubleshooting technical issues, identifying root causes, recommending repair options and explaining findings and limitations to customers.

- Planning and coordinating on-site activities, selecting and setting up portable equipment, and adapting methods to challenging working environments.

- Working in line with company procedures, customer requirements and applicable HSE rules; contributing to risk assessments, toolbox talks and safe working practices.

- Keeping accurate records of inspections, measurements, work completed, recommendations, progress, time and expenses.

- Preparing or contributing to service and project completion reports.

- Sharing field experience and feedback to help improve machining methods, tools, equipment and service processes.

- Supporting colleagues and contributing to a strong, collaborative service team.

Travel requirements

This role involves at least 60% domestic and international travel, including onshore and offshore assignments. You should be comfortable travelling at short notice and spending extended periods away from your usual work location. Assignments typically last from a few days to around a few weeks. Work is usually carried out in pairs, though some services require solo travel. The reporting location for this role is Hamburg.

What you’ll need to succeed

- 2–3 years’ relevant experience in in-situ machining, engine repair or a similar field service role.

- Experience with line boring, crankshaft machining or grinding, metal stitching, laser or optical alignment, and mechanical measurement.

- Experience calibrating and verifying tools; crankshaft machining tools and portable grinding equipment are an advantage.

- Ability to use machining equipment and software, and to read and interpret technical drawings.

- Strong practical troubleshooting and problem-solving skills, with a flexible, solution-oriented approach.

- Clear communication skills and the ability to work effectively with customers and colleagues, both independently and as part of a team.

- A customer-focused, proactive approach and attention to detail.

- A valid category B driving licence and strong written and spoken English.

- Willingness and flexibility to travel.
