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.

• 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.

• 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, Solid Works 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.
