As a Mechanical Design Engineer, you will be responsible for the complete design cycle of single-use fluid-handling systems, such as mixers and tubing solutions used in pharmaceutical production. Each project is unique and based on client input, requiring involvement in technical drawing, calculations, and validation. You will own the design process from feasibility through to validation and handoff. This includes creating and adapting 2D/3D technical drawings and P&ID diagrams, performing mechanical calculations, and selecting the appropriate system components. You’ll work closely with clients to refine designs and specifications and liaise with subcontractors in the Netherlands to ensure accurate manufacturing. You will also support project delivery activities such as FATs, SATs, and occasional on-site commissioning. All designs must be documented according to internal quality protocols, and you can expect to travel to vendors or client sites about once or twice a month.
