Essential Duties & Responsibilities: An individual in this position must be able to successfully perform the duties and responsibilities listed below. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions of this position. Additional duties may be assigned.

• Manage assigned engineering projects from concept through successful completion, including schedule, deliverables, and technical outcomes.
• Design, develop, and integrate engine systems and components, beginning with first principles engineering analysis and progressing through detailed design.
• Perform engineering calculations and simulations to support rotating assemblies, gear trains, pumps, and supercharger/turbocharger machinery.
• Select appropriate materials and manufacturing processes considering performance, longevity, reliability, weight, and cost targets.
• Lead requirements development and ensure verification and validation plans are established and executed for assigned systems, subsystems, and components.
• Develop and document test standards and protocols; analyze test data and provide actionable engineering recommendations.
• Collaborate proactively with engineers, technicians, drafters, suppliers, and program managers to optimize engine design, reliability, manufacturability, and performance.
• Design to achieve lowest manufacturing cost consistent with reliability, performance requirements, and FAA certification standards (e.g., 14 CFR Part 23 / Part 33 as applicable).
• Prepare and review engineering drawings in accordance with ASME drafting standards.
• Support production development, prototype builds, validation testing, and FAA certification activities as assigned.
• Contribute to continuous improvement initiatives and implementation of new and improved engineering and manufacturing processes.

Required Qualifications:

• Bachelor of Science in Mechanical Engineering or equivalent degree.
• Minimum 5 years of engine design experience, particularly involving rotating assemblies, gear trains, pumps, and/or supercharger/turbocharger machinery.
• Strong analytical skills with demonstrated ability to perform and interpret engineering calculations and test data.
• Excellent organizational and project management skills.
• Ability to effectively communicate with cross-functional teams including engineering, management, lab technicians, and suppliers.
• Proficiency in 3D CAD software (e.g., SolidWorks, PTC Creo, Siemens NX or equivalent).

Preferred Qualifications:

• Membership in professional engineering organizations such as SAE International or similar.
• Advanced engineering degree (MS or PhD) or relevant professional certification.
• Research & Development experience in propulsion or advanced mechanical systems.
• Knowledge of FAA certification regulations and compliance processes.
• Demonstrated passion for engines, high-performance technology, innovation, and aviation.

Key Competencies:

• Systems-level thinking
• Mechanical design expertise in high-speed rotating equipment
• Requirements management and validation discipline
• Cost-conscious design for manufacturability
• Data-driven decision-making
• Clear and concise technical communication

Work Environment: This role operates in a collaborative engineering environment and may include time in laboratory and production settings to support development, testing, and certification activities. If you are driven by innovation and thrive on solving complex propulsion challenges, this is an opportunity to help shape next-generation aviation engine systems.
