Employment: Full-time

Description: Mechanical Design Engineer (m/f/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/f/d)

Background:
The Liquid Handling Team in Rotkreuz is the team of experts for liquid handling solutions for our diagnostic instruments. In collaboration with the various project and product teams, we develop, maintain and test the fluid systems, pipetting and dosing solutions for our diagnostic instruments including mechanics, electronics, real-time software and algorithms for monitoring.
As a Mechanical Design Engineer - Expert in Fluid Dynamics, you will help to assess and develop new technologies in the area of ​​liquid handling for our IVD product development. You support the development of cost-efficient and reliable fluidics concepts that meet the system needs.
With your specialist knowledge in fluid dynamics, including experimental fluid dynamics, and your ability to understand 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 specialization in fluid dynamics. The ideal candidate has 1 to 3 years of experience with CFD software and 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# complete the profile.

Main tasks and areas of responsibility:
Concept assessment and parameter determination:
You analyze and evaluate 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 will support the design engineers in the development of components so that the design is optimized from a fluid technical perspective. You verify your simulations using experiments.

Feasibility studies:
You initiate, lead and carry out feasibility studies in the area of ​​liquid handling in order to meet technical requirements and minimize risks.

Test stand development:
You define the test stands required for the feasibility studies and parameter determinations. In collaboration with the mechanical and electronic design engineers and the software engineers, you will put the test stands into operation 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
-    Enjoy 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 sequences in Python and C#, and use modern AI tools such as Gemini or Claude Code to develop efficient solutions
-    You want Work in international, cross-functional teams and exchange ideas with other experts
-   Very good written and oral communication in German and English.
