Mechanical Design Engineer, Injection Molding – Humanoid (human)

Your mission & challenges

In our humanoid robotics department, we are seeking several outstanding humanoid robot developers to join our team. Your responsibilities will be:

• Development and design of injection-molded components and assemblies for humanoid robot systems

• Design for Manufacturing (DfM) and Design for Assembly (DfA) with a focus on suitability for series and large-scale production

• Design of plastic components under mechanical, thermal, and dynamic loads

• Close cooperation with toolmaking, manufacturing, suppliers, and external injection molding service providers

• Definition of material selection (e.g., engineering thermoplastics, fiber-reinforced plastics)

• Analysis and reduction of warping, sink marks, weld lines, and tolerance problems

• Support for sampling and series production start-ups

• Technical responsibility for plastic components throughout the entire product life cycle

What we can look forward to

Must-have:

• Degree in mechanical engineering, plastics technology, mechatronics, or comparable field

• Several years of experience in the design of injection molded parts

• Very good knowledge of injection molded component design:

  • Wall thicknesses

  • Radii

  • Rib and snap connections

  • Draft angles

• Experience with engineering plastics (e.g., PA, PBT, PC, ABS, PPS, fiber-reinforced)

• Confident use of CAD systems (CREO, SolidWorks, NX)

• Understanding of tolerance chains and quality assurance

• Knowledge of simulation (e.g., FEM, multibody)

• Good knowledge of German or English

Nice-to-have:

• Knowledge of Moldflow/injection molding simulation

• Experience with hybrid components, insert molding, or overmolding of metals
