Mechanical Design Engineer focusing on design and testing of mechanical subsystems for waste management solutions. Collaborating on product lifecycle in a fast-paced environment with real responsibility.
Responsibilities
Take ownership of key mechanical subsystems within Qualibot and Quantisort 2.0, designing, testing, and improving components.
Work across both the design and production teams, based mainly at our manufacturing centre in east London, with occasional site visits.
Focus on improving pneumatic ejection performance and packaging components to operate reliably in harsh, high-throughput environments.
Help move projects through client plant design, build, factory acceptance testing, and installation, while continuously improving processes to support scalability.
Design and develop mechanical components and assemblies in SolidWorks, including sheet metal, welded structures and full assembly drawings.
Own supplier engagement: RFQs, DFM discussions, cost reviews and order placement.
Design and iterate subsystems within the Quantisort 2.0 optical sorter (control panels, ejection systems, structural elements and vision system integration).
Conduct value engineering and cost-reduction initiatives.
Support installations and commissioning across Europe.
Provide first-line engineering support for field issues and contribute to root cause analysis.
Contribute to DFM/DFA improvements, build documentation and process optimisation.
Support R&D projects (e.g. pneumatic optimisation across varying waste streams).
Participate in design reviews and contribute to technical decision-making.
