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
