Mechanical Designer

Sierra Lobo, offers customers a full range of professional and technical capabilities, including Test and Evaluation, Systems Engineering, and Advanced Technologies.  We also develop products and processes related to Cryogenic Fluid and Thermal Management Systems, Densified Propellant Management Systems, and Prototype Extreme Pressure and Temperature Systems.  Our customers include the Department of Defense (DoD), the U.S. Air Force, U.S. Navy, U.S. Army, Missile Defense Agency (MDA), and the National Aeronautics and Space Administration (NASA).

Overview:

We are seeking early- to mid-career Mechanical Designers to support the design, development, integration, and documentation of mechanical hardware for aerospace and space exploration programs for our government and commercial customers.

The ideal candidate will have hands-on experience using Siemens NX and Teamcenter to develop 3D models, assemblies, detailed engineering drawings, and product definition packages. This individual will work closely with mechanical engineers, systems engineers, manufacturing engineers, and other technical disciplines to develop mechanical solutions that meet demanding performance, reliability, and mission requirements.

This position offers the opportunity to contribute to challenging aerospace projects involving precision mechanical components, complex assemblies, and spaceflight hardware.

Key Responsibilities:

• Create and modify 3D mechanical models, assemblies, and detailed engineering drawings using Siemens NX.
• Develop mechanical designs for brackets, structural components, mechanisms, enclosures, mounts, and other aerospace hardware.
• Create and maintain engineering product data, including parts, assemblies, drawings, and associated documentation in Teamcenter.
• Support engineering configuration management, product lifecycle management (PLM), and engineering change processes.
• Apply mechanical design principles, geometric dimensioning and tolerancing (GD&T), and engineering drawing standards.
• Work with mechanical engineers to translate design concepts and engineering requirements into manufacturable hardware.
• Support design reviews, drawing reviews, and design updates throughout the product development lifecycle.
• Collaborate with manufacturing, assembly, integration, and test teams to resolve design and fabrication issues.
• Incorporate design changes based on engineering analysis, manufacturing feedback, and test results.
• Ensure designs comply with applicable aerospace design practices, quality requirements, and configuration control processes.

Required Qualifications:

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Mechanical Engineering Technology, or a related technical discipline; equivalent relevant experience may be considered.
• Approximately 2–7 years of mechanical design experience in an engineering or product development environment.
• Demonstrated proficiency with Siemens NX for 3D modeling, assembly design, and engineering drawings.
• Experience with Siemens Teamcenter for product data management, configuration control, and engineering documentation.
• Understanding of mechanical design fundamentals, manufacturing processes, and engineering drawing practices.
• Working knowledge of GD&T and dimensional tolerancing.
• Ability to interpret engineering specifications, sketches, drawings, and technical requirements.
• Strong attention to detail and ability to work effectively within a multidisciplinary engineering team.
