Roche Schweiz bridges the gap between pharmaceuticals and diagnostics. Important research and development functions are located here. For our long-standing client, Roche Diagnostics International AG in Rotkreuz, we are looking for a

Mechanical Design Engineer - Expert in Fluid Dynamics
=========================================================

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 algorithms for monitoring.

As a Mechanical Design Engineer - Expert in Fluid Dynamics, you will help to assess and develop new technologies in the field of liquid handling for our IVD product development. You will support the development of cost-effective 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 knowledge in Python and C# round off the profile.

Tasks & Responsibilities:

• 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 technology perspective. You verify your simulations using 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
• Joy in 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 to work in international, cross-functional teams and exchange ideas with other experts
• Very good written and oral communication in German and English.

What is offered to you:

• A chance to contribute to one of the most significant pharmaceutical companies in the world
• Modern campus with lots of green spaces and meeting zones
• Central location with motorway connection and train station nearby
• Varied activity profile
• Home office possibility
• Further training opportunities through temptraining
• Collaboration in a dynamic and motivated team
• Good remuneration
