Senior Mechanical Design Engineer - Microjet

The role owns micro-jet engine mechanical work packages end-to-end—from initial requirements capture, concept trade studies, and 3D CAD modeling through to drawing release, manufacturing, engine build, rig/engine testing, and design maturation. Roles & Responsibilities: • Lead the mechanical design and technical development of micro-jet engine components and assemblies. • Develop and integrate 3D CAD models for compressor and turbine hardware, rotors and stators, shafts, bearings, housings, casings, seals, flanges, nozzles and associated structures. • Perform structural, thermal and rotating-machinery analyses, including static and rotating loads, fatigue, vibration, buckling, thermal loads and thermo-mechanical behaviour. • Conduct FEA and assess stresses, thermal growth, clearances, critical speeds and high-temperature material behaviour. • Produce and review engineering drawings, GD&T, tolerance stack-ups, fits, materials, coatings, heat treatments and inspection requirements. • Support manufacturing, assembly, balancing, commissioning and testing activities. • Investigate mechanical and structural issues identified during build and testing, including vibration, leakage, clearances, thermal behaviour and bearing or joint-related anomalies. • Correlate analytical and FEA results with component, rig and engine-test data and support design improvements based on findings. • Coordinate with suppliers on technical specifications, manufacturing plans, drawing reviews, deviations, non-conformances and acceptance requirements. • Prepare and present technical evidence during design and readiness reviews, including PDR, CDR and TRR. • Provide technical guidance and mentorship to junior engineers. Required Skills & Qualifications: • Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering or a related discipline. • Typically 7–12 years of relevant engineering experience, with demonstrated ownership of hardware through design, manufacture, assembly, testing and maturation. • Advanced proficiency in 3D CAD and engineering drawing development using Siemens NX, CATIA, Creo, SolidWorks or equivalent. • Strong practical FEA experience using Ansys Mechanical, Abaqus, Nastran or equivalent. • Strong knowledge of solid mechanics, structural dynamics, heat transfer, fatigue, rotating-component stresses and temperature-dependent material behaviour. • Practical understanding of gas-turbine mechanical architecture and rotating machinery, including shafts, bearings, compressor/turbine interfaces, casings, seals and running clearances. • Working knowledge of rotor dynamics, vibration, balancing and critical-speed considerations. • Strong knowledge of GD&T, ISO GPS or ASME Y14.5, tolerance analysis and aerospace manufacturing processes. • Experience supporting engine or rotating-machinery builds, testing, troubleshooting and supplier coordination. • Strong technical communication, engineering judgement and ability to operate independently within a multidisciplinary engineering environment.
