Job Description

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 aerospace, defence, and autonomous applications. Our solutions support fixed- and rotary-wing UAVs as well as other advanced platforms, driving innovation and performance in aerospace propulsion.
Job Overview
The Senior Mechanical Engineer - Compressor Systems will lead the mechanical development of compressor hardware across multiple stages, focusing on delivering robust, high-performance, and manufacturable solutions for both low- and high-pressure compressor (LPC/HPC) modules in modern turbofan engines.
This role includes design responsibility for rotating and static components, collaboration with cross-functional teams, and lifecycle support from concept through production and in-service maturity. Candidates must demonstrate expertise in turbomachinery mechanics, structural integrity, and advanced aerospace propulsion engineering.
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 across 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 for 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 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.
Qualifications & Experience
Bachelor's degree in Mechanical or Aerospace Engineering required; Master's preferred, with concentration in turbomachinery or structural mechanics
7-10 years of mechanical design experience in turbomachinery, focusing 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
Preferred:
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
Personal Attributes:
Strong mechanical intuition and engineering judgment
Proactive problem-solver balancing performance, reliability, and manufacturability
Excellent collaboration skills in multi-disciplinary environments
Detail-focused, quality-driven, and responsive to fast-paced development cycles
Passion for innovation and continuous technical growth
