Design & Simulation Engineer (CREO / Fusion 360 / COMSOL) (f/m/d)| Full time | Vienna
Introduction
We are the technology leader in designing and building LBS display systems outperforming the competition in terms of size, power consumption, brightness and image quality.
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.
Your tasks
Tasks
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
Requirements
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.
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
