About the job

Mechanical Design Engineer (m/f/d)

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

Project:
For our client 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 expert team for liquid handling solutions of our diagnostic instruments. In collaboration with 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 help to assess and develop new technologies in the field of liquid handling for our IVD product development. You support the creation of cost-efficient and reliable fluidic concepts that meet system requirements.

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

The perfect candidate is a qualified person with a background in mechanical engineering specialising in fluid dynamics. The ideal candidate brings 1 to 3 years of experience with CFD software and simulation techniques (including grid generation, simulation and post-processing). Strong analytical skills, a structured approach to solving complex problems and enthusiasm for experimental fluid dynamics are also required. Practical knowledge in developing test setups as well as programming skills in Python and C# complete the profile.

Main tasks and responsibilities:
Concept assessment and parameter determination:

You analyse and assess new technologies and test them. Using your fluidic and physical expertise, you define various parameter settings and verify them to achieve the pipetting performance required for the specific application.

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 assist design engineers in developing components to optimise the design 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 minimise risks.

Test stand development:

You define the required test stands needed for feasibility studies and parameter determinations. In collaboration with mechanical and electronic design engineers and software engineers, you commission the test stands and programme the necessary software processes.

Must haves:
- Completed degree, Bachelor or Master of Science in Mechanical Engineering specialising in Fluid Dynamics

• 1-3 years of experience with CFD software and techniques to simulate complex fluid flows, including grid generation, simulation and post-processing
• Strong analytical skills and an independent and structured approach to analysing and solving complex problems
• Enjoyment of experimental fluid dynamics and hands-on work with test setups to confirm theories and verify the performance of the setups
• Ability to programme complex test procedures in Python and C#, and to use modern AI tools such as Gemini or Claude Code to develop efficient solutions
• Desire to work in international, cross-functional teams and exchange ideas with other experts
• Very good written and oral communication skills in German and English.
