Hardware Design Intern

We are looking for a motivated Hardware Design Intern / Working Student to join our Hardware team and support the development of medical imaging products.

In this role, you will work closely with experienced hardware engineers and gain hands-on exposure to the full product lifecycle: from early mechanical design and prototyping to testing, documentation, and support of production and logistics.

This is a practical, learning-oriented role, ideal for engineering students who want real-world experience in hardware product development within a fast-growing healthtech company.

● Support mechanical and hardware product development, including new designs and improvements to existing products

● Create and modify CAD designs using Autodesk Fusion 360

● Prepare and execute 3D prototyping (mainly FDM using Prusa printers; occasional SLA)

● Assist in testing and validation of prototypes and products

● Prepare technical drawings and support tolerance definition

● Support design for manufacturing activities (SLS, CNC) and cost optimization

● Help maintain technical documentation (BOMs, manufacturing and assembly instructions)

● Assist with product lifecycle management, including version control and Engineering Change Orders (ECOs)

● Support product assembly, packaging, and logistics activities when required

● Collaborate with hardware, supply chain, and production stakeholders

● Currently enrolled in a Bachelor’s or Master’s degree in Mechanical Engineering, Industrial Design, Biomedical Engineering, or similar

● Basic experience with CAD design (Fusion 360 preferred)

● Interest in hardware development, prototyping, and manufacturing

● Hands-on mindset and willingness to work with physical products and tools

● Ability to work in a structured way and document your work clearly

● Good communication skills in English (spoken and written)

Nice to have

● Experience with 3D printing (FDM and/or SLA)

● Basic understanding of manufacturing processes (CNC, SLS, injection molding)

● Familiarity with technical drawings and tolerances

● Interest in medical devices or regulated products

● Experience with tools such as Blender, Inkscape, or slicers (PrusaSlicer, Lychee)
