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



Why Join TriLite?
* Be part of a dynamic, ambitious, and international team with flat hierarchies
* Startup-like environment with real influence and creative freedom
* Work on exciting, cutting-edge projects with leading international companies
* Excellent learning and development opportunities, tailored to your strengths
* Strong culture of collaboration, team spirit, and innovation
* Sustainable mobility: JobRad bicycle program
* Gym membership to support your well-being
* Regular company and team events
* Modern headquarter in the center of Vienna (1040)
* Flexible working hours and the possibility of home office



Compensation & Legal Information
* Minimum salary: €51,156.70 gross per year, based on the Austrian collective agreement for the metal industry
* The actual salary will be determined individually based on your qualifications and experience
* Applicants must have a valid work permit for Austria
