HR Business Partner


As a Senior Mechanical Engineer at C-Job Naval Architects, you are responsible for the design and integration of technical systems onboard ships or other floating structures. These systems pertain to propulsion, energy supply, and those required for the crew and passengers, such as potable and waste water provisions, and ventilation, AC, and/or heating. Your daily challenge is to ensure regulations and client requirements seamlessly integrate into a well-functioning, efficient ship design.

You use your professional maturity and years of experience to actively participate in internal and external project kick-offs. Leveraging a range of software programs, you design, develop, and test technical solutions. You create 2D or 3D technical drawings and system diagrams, which are supported and verified through your calculations.

As a senior engineer, you are expected to mentor, coach, and educate less experienced engineers, ensuring their work meets high-quality standards before it's sent to the client. You also support the lead engineer in managing client and stakeholder expectations at a technical level and communicate engineering choices with other disciplines within the project. Depending on the size of a project, you also have direct contact with the client.

Joining the mechanical department, you'll collaborate with a multifaceted team whose size and structure adapt to project needs. Your joint efforts span various projects across offshore, yacht construction, and dredging sectors. This role offers an opportunity to work on multiple projects concurrently, each unique in its scope and scale. The global reach of C-Job also means you get to collaborate with colleagues from different offices worldwide.

If you enjoy devising solutions for complex technical issues as part of a team, and you find it challenging to work in an iterative approach, rather creating new solutions, then this job is for you.

Firsthand experience

There is an upcoming client meeting where approval must be given for a solution to a technical challenge. How do you proceed?

As a senior eningeer, your role varies depending on the project's size. You contribute with your team in brainstorming a solution for the technical challenge, aiding in its visualization through sketches or 3D renderings. You collaborate with seniors/leads from other disciplines to ensure the solution's feasibility. For smaller projects, you might directly present the team's collective proposal to the client. However, for larger projects, your team's agreed solution is handed over to the lead engineer or project manager for presentation in the client meeting.


A senior mechanical engineer is advancing to a role as a lead, an expert, or a project manager. Both 'horizontal' in-depth development as well as 'vertical' development are possible in this progression.
