Mechanical Design Engineer (m/w/d)

Mechanical Design Engineer (m/w/d)-Fluid Dynamics/CFD Software/C#/Python/German

Project:
For our customer Roche Diagnostics International AG based in Rotkreuz, we are looking for a Mechanical Design Engineer (m/w/d)

Background:

The Liquid Handling Team in Rotkreuz is the expert team for liquid handling solutions of our diagnostic instruments. In cooperation with the various project and product teams, we develop, maintain, and test the fluid systems, pipetting, and dispensing solutions for our diagnostic instruments, including mechanics, electronics, real-time software, and monitoring algorithms.

As a Mechanical Design Engineer - Expert in Fluid Dynamics, you will help assess and develop new technologies in the field of liquid handling for our IVD product development. You will support the development of cost-efficient and reliable fluidic concepts that meet the system requirements.

With your expertise in fluid dynamics, including experimental fluid dynamics, and your ability to grasp the overall system context, you will contribute significantly to the success of our future diagnostics portfolio.

The perfect candidate is a qualified person with a background in mechanical engineering and a specialization in fluid dynamics. The ideal candidate brings 1 to 3 years of experience with CFD software as well as simulation techniques (including grid generation, simulation, and post-processing). In addition, strong analytical skills, a structured way of working to solve complex problems, and enthusiasm for experimental fluid dynamics are required. Practical knowledge in the development of test setups as well as programming skills in Python and C# round off the profile.

Main tasks and areas of responsibility:
Concept assessment and parameter determination:

You analyze and assess new technologies and test them. Using your fluidic and physical expertise, you define various parameter settings and verify them so that the pipetting performance of the specific application can be achieved.

Liquid handling solution development:

You support the technical implementation of liquid handling solutions in the context of IVD product developments. Using your fluidic and physical expertise and Computational Fluid Dynamics, you support the design engineers in the development of components so that the design is optimized from a fluid technical perspective. You verify your simulations through experiments.

Feasibility studies:

You initiate, lead, and conduct feasibility studies in the field of liquid handling to meet technical requirements and minimize risks.

Test stand development:

You define the required test stands needed for the feasibility studies and parameter determinations. In cooperation with the mechanics and electronics design engineers and the software engineers, you commission the test stands and program the required software processes.

Must Haves:

• Completed studies, Bachelor or Master of Science in mechanical engineering in the field of fluid dynamics
• 1-3 years of experience with CFD software and techniques to simulate complex fluidic flows, including grid generation, simulation, and post-processing
• Great analytical skills and an independent and structured approach to analyze and solve complex problems
• Enjoyment of experimental fluid dynamics and enjoy working hands-on on test setups to confirm theories and verify the performance of the setups
• Ability to program complex test processes in Python and C#, and use modern AI tools such as Gemini or Claude Code to develop efficient solutions
• You want to work in international, cross-functional teams and exchange ideas with other experts
• Very good written and oral communication in German and English.
