Experience
Mechanical Design Engineer
Pennine Rotive Systems · Manchester, UK
- Redesigned a pump housing around a revised tolerance stack, cutting warranty returns for seal failure from 4.1% to 1.3% across the following production year.
- Ran finite element analysis on three bracket concepts and selected the variant that held the load case at 22% less material, which suppliers quoted as a £46k annual saving.
- Led design-for-manufacture reviews with two machining vendors, removing five secondary operations from a housing family and shortening lead time by nine days.
Graduate Mechanical Engineer
Calderfield Engineering · Leeds, UK
- Built and instrumented a test rig for gearbox vibration, producing the measurement set the team used to reject an under-specified bearing before tooling was committed.
- Converted a legacy 2D drawing set to parametric CAD models, cutting the time to generate a customer variant from two days to under three hours.
- Documented material and finish standards for a product line, giving procurement a single reference that reduced supplier clarification requests noticeably.
