Sr. Specialist Mechanical Engineer – Design (Level 4)

Position Overview

We are seeking a Senior Specialist Mechanical Design Engineer (Level 4) to support the design and development of turbomachinery and propulsion hardware for advanced liquid rocket engine systems. This onsite contract role in Los Angeles, CA (Onsite) follows a 9/80 work schedule and offers a potential conversion to direct hire. You will collaborate across engineering, manufacturing, quality, and supplier teams on mission-critical aerospace programs, delivering high-performance mechanical designs that meet demanding system, cost, and producibility requirements.

Key Responsibilities

• Apply advanced mechanical design principles to complex propulsion systems used in spacecraft and missile applications.
• Design and develop turbomachinery components and assemblies for liquid rocket engines.
• Create and interpret 3D CAD models and detailed engineering drawings.
• Perform tolerance analyses and trade studies to support design optimization.
• Evaluate and incorporate technical input from suppliers and manufacturing partners.
• Execute detailed design tasks including CAD modeling, tolerance studies, and specification development.
• Prepare engineering drawings using GD&T in accordance with ASME Y14.5 standards and participate in design reviews.
• Support production activities by assisting with hardware installation, testing, and nonconformance resolution.
• Develop technical documentation, reports, and presentations for internal and external stakeholders.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering or a related discipline.
• Minimum 2 years of directly related experience, or an equivalent combination of education and experience.
• Strong foundation in machine design, fluid mechanics, and strength of materials.
