Mechanical Design Senior Engineer

About POWERTECH

POWERTECH is a center of excellence for propulsion technologies, specializing in the design, engineering, and manufacturing of combustion engines, expendable turbojet engines, and turbofan engines for a wide range of aerospace, defence, and autonomous applications, including fixed- and rotary-wing UAVs and other advanced platforms.

Position Summary:

The Senior Mechanical Design Engineer will lead the mechanical design and development of rotating engine components like shaft, compressor, turbine and bearings in state-of-the-art turbofan propulsion systems. This role is responsible for the structural integrity, performance, and manufacturability of rotors, stators, casings, and sealing systems. The engineer will collaborate with multidisciplinary teams to deliver reliable, efficient, and certifiable designs from concept through production, contributing to both commercial and military engine programs. The position provides technical leadership within complex, multidisciplinary propulsion programs, combines deep technical expertise with project coordination, and cross-functional collaboration across performance, mechanical, and software teams.

Key responsibilities:

• Lead the end-to-end design of rotating hardware
• Develop detailed 3D CAD models and 2D engineering drawings (CATIA, NX).
• Ensure mechanical integrity under combined thermal, centrifugal, vibratory, and aerodynamic loads across all phases of engine operation.
• Work with structural analysts to validate designs using stress analysis, modal/harmonic response, fatigue, creep and oxidation life assessments.
• Drive design optimization for performance, weight, and durability while maintaining safety margins for certification.
• Implement Design for Manufacturability (DFM) with forged, cast, and machined components using advanced materials (e.g., nickel-based superalloys).
• Define precision tolerances, fits, and coatings to meet production needs.
• Collaborate with manufacturing and suppliers to resolve producibility issues, support tooling reviews, and ensure successful hardware delivery.
• Assist in test and assembly integration activities, resolving mechanical interface challenges.
• Produce comprehensive design documentation, including:
  
  

• Coordinate with aerothermal, structural, thermal, materials, and systems engineering teams to ensure robust turbine design integration.
• Interface with test and validation teams during rig and engine testing phases.
• Participate in root cause analyses (RCA) and design iterations based on field and test findings.
  
  

• Bachelor’s degree in Mechanical or Aerospace Engineering required
• Master’s degree preferred, especially with focus on turbomachinery or hot-section design
• 8+ years of experience in mechanical design of turbomachinery components, preferably in the turbine or hot section
• Proven track record in leading LPT component design through development, test, and certification phases
• Proficiency in 3D CAD software (CATIA, NX, or equivalent)
• Familiarity with FEA tools and interpretation of stress, vibration, and fatigue data
• Strong understanding of high-temperature materials and cooling design principles
• Knowledge of FAA/EASA certification standards and ARP/MIL specifications
• Expertise in GD&T, tolerance analysis, and technical documentation practices
  
  

• Experience with advanced turbine cooling, film cooling, or thermal barrier coatings
• Familiarity with integrally bladed rotors (IBRs), blisks, or brazed vane structures
• Exposure to rig and engine-level testing and instrumentation
• Understanding of digital thread practices and model-based engineering (MBE)
  
  

• Strong mechanical intuition and design judgment
• Collaborative mindset with cross-functional communication skills
• Detail-oriented, results-driven, and responsive to fast-paced project needs
• Passion for technical innovation and continuous improvement in propulsion systems
