Mechanical Design Engineer

As we ramp up design, development and production, we want to expand our mechanical team. We are looking for engineers who enjoy technical challenges and want to help further develop our hydrogen fuel cell systems, hydrogen storage systems and thermal management.

If you are interested in us, we are probably interested in you too. So introduce yourself to us and we’ll see if we’re a match for each other.

As a mechanical design engineer your responsibilities will lie in the fields of fuel cell, hydrogen storage or thermal management systems development. All three subsystems are of vital importance for a reliable and competitive zero emission operation. The core subsystems you will develop and test will be integrated into a vast variety of applications, ranging from maritime over automotive to aviation applications.

The fuel cell system is the heart of the operation. A compact design enables smart placement of the fuel cell in the application. High efficiency lowers consumption and increases range and endurance. High reliability is a must to be able to replace proven diesel technology. Production scalability through building block approach. As a design engineer for hydrogen fuel cell systems you have to combine a wide set of skills optimising a mechanical design consisting of several subsystems. You will be dealing with different media, temperatures, material specifications and other requirements. The subsystems of the fuel cell system deal with hydrogen, pure water, coolant, high and low voltage. Working on fuel cell modules includes the work of integrating existing components but also developing inhouse components and subsystems.

The largest and heaviest subsystem in most hydrogen applications is the hydrogen storage. The hydrogen storage reaches from the refuelling port on the vehicle, ship or generator via the tanks to the hydrogen interface on the fuel cell module. A large set of high pressure equipment needs integration along the way. At pressures of 350 to 700 bar safety and reliability are of utmost importance. Certification requirements in the different sectors ask for different design approaches in the different applications. The higher the hydrogen capacity, the longer the machine or truck can run before refuelling. The lighter the construction the higher the possible payload. Well performed structural design and analysis results in the largest performance gain when it comes to the  hydrogen storage system.

Keeping all systems at their optimum working temperatures is key to enable smooth and reliable operation. Depending on the operation the thermal management subsystem can dictate the maximum power output of the fuel cell system, the more compact and efficient the design, the better the fuel cell performance also at high environmental temperatures. The design and working principle can differ from application to application. Where maritime applications can rely on liquid to liquid heat exchangers, trucks or stationary generators require large surfaces for gas (air) to liquid radiators, larger in size than their diesel counterpart. The thermal management system, an important building block of the hydrogen fuel cell powertrain, filled with challenges and room for novel developments.

You will facilitate your colleagues, the mechanical integration engineers, integrating your core subsystem into a customer specific zero emission solution.

Task description

Designing mechanical components and systems in 3D-CAD, based on a large set of requirements is an important part of your job. You analyse them via FEA methods on their strength, mechanically stress test the components to verify the FEA and afterwards integrate new components and/or subsystems in the existing product, the fuel cell, thermal management or hydrogen storage system. You are responsible for the entire development cycle of your newly developed component/product. For new products/prototypes this also includes managing production and assembly.

Together with colleagues of other departments and specialisations you will perform system tests on the testbench and in the actual real life application in the field, being in a ship, truck or excavator.

We are looking for engineers who can easily adapt to the diversity of tasks that arises when working in a young and growing company. Team players who know how to mechanically design and integrate in a practical matter and understand the importance of durability.

Job in a nutshell

  • You will acquire detailed knowledge of the working principles of zepp products
  • You will play an important role in the development of future subsystems as well as technical upgrades on existing series
  • Analyse system/subsystem/component requirements
  • Support integration engineers to fulfil application specific system requirements
  • Develop mechanical components and systems, from 3D-CAD to final integration (design, FEM analysis, production drawings, assembly)
  • Support testing campaigns of new series

Our needs and wants

  • Open and driven to play an essential role in zepp’s contribution to the energy transition
  • Experience/skills in 3D-CAD modelling
  • Minimum HBO degree/level in Mechanical Engineering or similar
  • Understanding of load and strength calculations, applied on FEM analysis
  • Keen desire to gain practical knowledge through some hands-on work/workshop
  • Proficient level of English with effective communication skills

Note this

  • Temporary contract with a clear prospect of permanent employment
  • 40 hours work week, time-for-time
  • Salary € 3.000 – € 4.200 depending on relevant knowledge and experience
  • 30 days leave per year (1 FTE)
  • Located in the historic city centre of Delft and innovation hotspot RDM in Rotterdam
  • The starting date is flexible
