Mechanical Engineer

Leidos • Huntsville, AL

8d • $87,100 - $157,450

About The Position

Leidos Defense Systems is seeking a Mechanical Engineer to join its Hypersonics line of business and support hypersonic development programs. The role contributes to advanced weapon system development efforts, supporting the design and development of mechanical components and assemblies for advanced hypersonic vehicles.

The engineer creates and maintains Technical Data Package artifacts, including drawings, bills of materials, and specifications, and manages technical interface control drawings and related engineering documentation. Designs must account for functionality, manufacturability, assembly, inspection, and producibility. The role applies GD&T and tolerance analysis, supports material and manufacturing-process selection, and participates in product-development reviews and meetings.

The engineer also supports prototype fabrication, assembly, integration, and testing by troubleshooting mechanical issues and developing engineering solutions in coordination with senior engineers. The position involves collaboration with structural, thermal, systems, manufacturing, quality, and test engineering teams; independently managing assigned tasks and projects with guidance from senior engineers; and working in classified and unclassified environments as required.

Requirements

• Active DoD Secret security clearance.
• Bachelor’s degree in engineering from an ABET-accredited institution and 4+ years of relevant experience, or a master’s degree and 2 years of experience.
• Proficiency with 3D CAD tools such as Creo, CATIA, AutoCAD, SolidWorks, or similar software.
• Experience working within Product Lifecycle Management (PLM) environments.
• Working knowledge of GD&T in accordance with ASME Y14.5 and basic tolerance stack-up analysis.
• Understanding of engineering drawings, specifications, and configuration management processes.
• Fundamental understanding of mechanical design principles, including statics, mechanics of materials, materials science, and manufacturing processes.
• Willingness to facilitate technical meetings with internal and external stakeholders, including design, peer, and tabletop reviews.
• Ability to communicate technical information effectively through written documentation, drawings, presentations, and verbal communication.
• Strong attention to detail, analytical thinking, problem-solving, communication, and collaboration skills.
• Self-starter with eagerness to learn, take ownership of assigned tasks, and grow technically in a fast-paced engineering environment.
• Proficiency with Microsoft Office applications, including Word, Excel, and PowerPoint.

Nice To Haves

• Experience supporting DoD programs involving missile systems, reentry vehicles, hypersonic systems, or other advanced aerospace technologies.
• Experience supporting rapid development, prototyping, or fast-paced engineering programs.
• Experience creating 3D models and engineering drawings using PTC Creo and managing data within Windchill.
• Familiarity with aerospace materials and manufacturing processes, including machining, composites, additive manufacturing, welding, bonding, and mechanical fastening.
• Hands-on experience supporting hardware fabrication, assembly, integration, or testing.
• Familiarity with structural and/or thermal analysis as it relates to mechanical design.

Responsibilities

• Support the design and development of mechanical components and assemblies for advanced hypersonic vehicles.
• Create and maintain Technical Data Package artifacts, including drawings, bills of materials, and specifications.
• Manage and maintain technical interface control drawings and associated engineering documentation.
• Develop mechanical designs considering functionality, manufacturability, assembly, inspection, and producibility.
• Apply GD&T principles in accordance with ASME Y14.5 and applicable engineering drawing standards.
• Perform tolerance analyses and engineering calculations to support design decisions and verify component and assembly requirements.
• Participate in design reviews, peer reviews, drawing reviews, and other technical meetings throughout the product development lifecycle.
• Support selection of materials, manufacturing processes, finishes, fasteners, and other mechanical design features appropriate for aerospace and defense applications.
• Support prototype fabrication, assembly, integration, and testing by troubleshooting mechanical issues and developing engineering solutions in coordination with senior engineers.
• Collaborate with structural, thermal, systems, manufacturing, quality, and test engineering teams to develop and mature mechanical designs.
• Independently manage tasks and projects with guidance from senior engineers.
• Perform work in classified and unclassified environments as required.
