Turbojet Mechanical Stress Engineer

About the role

Destinus develops Unmanned Aerial Vehicles (UAVs) for the defense industry and is looking for a Turbojet Mechanical Stress Engineer in Madrid. The engineer ensures the structural integrity of turbojet engine components, working from early concept through testing and production alongside multidisciplinary teams.

Key responsibilities

• Perform structural, thermal and thermo-mechanical analyses of turbojet components using analytical methods and Finite Element Analysis (FEA)
• Assess centrifugal, thermal, vibratory and combined loading on rotating and stationary engine hardware
• Evaluate the mechanical integrity and durability of compressor and turbine wheels, shafts, blisks, casings, bearing supports, combustor structures and exhaust components
• Predict thermal growth and hot-to-cold geometry changes to optimise running clearances
• Perform fatigue, creep, thermo-mechanical fatigue and durability assessments for high-temperature components
• Analyse bearings, shafts, interference fits, couplings, mechanical joints and sealing systems under operational loading
• Develop detailed FEA models and analytical calculations, define critical load cases and correlate them with rig, endurance and flight test results
• Collaborate with design, manufacturing, aerodynamics, combustion and test engineers, and prepare technical documentation for engine qualification and certification

Required profile

• Bachelor's or Master's degree in Aerospace, Mechanical or a related engineering discipline
• 3 to 8 years of experience in structural or mechanical integrity analysis for gas turbine or turbojet engines
• Strong understanding of rotating machinery under high centrifugal and thermal loads
• Experience with NX Simcenter, fatigue analysis, durability assessment and thermal deformation
• Familiarity with aerospace manufacturing processes such as machining, casting, additive manufacturing and heat treatment
• Professional English; security screening and a Certificate of Conduct (VOG) are required

Required skills

• NX Simcenter
• Classical stress calculations, structural sizing, fatigue and durability analysis
• Creep and thermo-mechanical fatigue
• Advantage: MATLAB or Python
