Senior Mechanical Design Engineer - Compressor

About us

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.

Job Overview:

The Senior Mechanical Engineer – Compressor Systems will lead the mechanical development of compressor hardware across multiple stages, with a focus on delivering robust, high-performance, and manufacturable solutions for both low- and high-pressure compressor (LPC/HPC) modules in modern turbofan engines. The role encompasses design responsibility for rotating and static components, integration with cross-functional teams, and lifecycle support from concept through production and in-service maturity. This position demands strong expertise in turbomachinery mechanics, structural integrity, and engineering excellence across advanced aerospace propulsion systems.

Key Responsibilities

Mechanical Design & Development

• Lead design efforts for key compressor components, including:

• Rotor discs, drums, and spools
• Blades and vanes (airfoils, dovetails, roots, platforms)
• Cases, spacers, shafts, and retention hardware
• Seal segments, shrouds, and tip clearance features

• Create detailed 3D CAD models and 2D drawings using CATIA, NX, or equivalent systems.
• Ensure design compliance with structural, vibratory, thermal, and aerodynamic requirements for all mission phases.

Structural Analysis & Optimization

• Collaborate with structural and lifing teams to assess:

• Static stress, fatigue (LCF/HCF), creep, and fracture tolerance
• Modal and harmonic response of rotating and stationary components
• Tip rub, blade flutter, and structural damping behavior

• Support design trade studies, margin assessments, and weight-reduction initiatives while maintaining reliability and certification standards.

Manufacturing & Producibility

• Apply Design for Manufacturability (DFM) principles to components produced via forging, casting, machining, and additive manufacturing.
• Define tolerances, surface treatments, coatings, and interface specifications.
• Coordinate with internal manufacturing teams and suppliers to resolve fabrication issues, tooling challenges, and cost targets.
• Participate in manufacturing readiness reviews, root cause analysis (RCA), and design iteration loops.

Documentation & Certification

• Generate detailed design documentation, including:

• Component definition drawings, stack-ups, and specifications
• Engineering reports for internal reviews and customer/stakeholder presentations
• Certification support packages for FAA, EASA, and military authorities

• Prepare and participate in design reviews (PDR, CDR) and audits.

Cross-Functional Collaboration

• Collaborate closely with:

• Aerothermal engineers on flowpath integration and stage matching
• Structural and dynamics teams on safe design margins
• Materials and process engineers for alloy selection, coatings, and durability
• Test and validation teams for rig and engine-level test execution

• Integrate compressor hardware into broader engine system architecture and ensure compatibility with adjacent modules.

Innovation & Technology Development

• Drive the development and adoption of advanced mechanical features such as:

• Integrally bladed rotors (IBRs/blisks)
• Lightweight structures using advanced alloys or composites
• Non-traditional tip clearance and blade retention methods

• Apply lessons learned and continuous improvement practices to reduce cycle time, improve durability, and enhance performance.

Experience and Education

• Bachelor’s degree in Mechanical or Aerospace Engineering required
• Master’s degree preferred, with concentration in turbomachinery or structural mechanics
• 7–10 years of mechanical design experience in turbomachinery, with a focus on compressor components
• Demonstrated success through full development lifecycle: concept, design, validation, production, and field support

Key Skills

• Expertise in CAD modeling tools (CATIA, NX)
• Familiarity with FEA tools and structural validation methods (ANSYS, Abaqus)
• Strong understanding of rotating machinery dynamics, vibration, and stress behavior
• Knowledge of FAA/EASA certification standards and aerospace design best practices
• Proficiency in GD&T, tolerance analysis, and technical documentation
• Experience with high-speed rotating components and complex assemblies
• Familiarity with advanced cooling methods, rub-tolerant seals, or compressor surge management
• Knowledge of additive manufacturing for rotating hardware or seals
• Understanding of digital thread, PLM systems, or model-based engineering
