Senior Mechanical Design Engineer - Compressor
Job Description
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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Bachelors degree in Mechanical or Aerospace Engineering required
- Masters degree preferred, with concentration in turbomachinery or structural mechanics
- 710 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
- 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
