Shape the future of precision engineering at TriLite.

At TriLite, we push the boundaries of high-precision opto-mechanical systems. As part of our growing, international engineering team, you will play a key role in designing and simulating advanced mechanical components that directly impact product performance and innovation.

This role is ideal for an experienced mechanical engineer who enjoys combining hands-on design work with simulation-driven engineering, and who wants to see their ideas move quickly from concept to prototype to production.

Your Role & Impact In this position, you will contribute to the full product lifecycle-from early design concepts through simulation, validation, and manufacturing readiness. You will work on high-precision components and assemblies, optimizing them for:

• Thermal performance
• Acoustic behavior
• Mechanical stability
• Manufacturability

You will collaborate closely with experts in product development, electronics, MEMS engineering, and Operations, ensuring your designs meet both technical and real-world constraints.

Your responsibilities:

• Design and develop mechanical components and assemblies using CREO and/or Autodesk Fusion 360
• Perform thermal and acoustic simulations using COMSOL Multiphysics
• Analyze, validate, and optimize designs based on simulation and test results
• Support prototyping, testing, and iterative design improvements
• Document designs, simulation setups, and key engineering decisions
• Actively collaborate with cross-functional teams across the organization

Your profile:

• Bachelor's or Master's degree in Mechanical Engineering or a related field
• At least 4 years of hands-on experience with COMSOL Multiphysics
• Strong experience with CREO and/or Autodesk Fusion 360 (or comparable CAD tools)
• Solid understanding of thermal and acoustic simulations and physics-based modeling
• Experience in mechanical design and product development
• Analytical, structured, and solution-oriented working style
• Ability to work both independently and within cross-functional teams
• Fluent English (German is a plus, but not required)

Nice to have (but not required):

• Multiphysics simulations beyond thermal/acoustics
• Prototyping and validation experience
• Manufacturing knowledge
• Basic programming skills (e.g. MATLAB, Python)
• Experience in opto-mechanical systems, or MEMS
