Job Title: Mechanical Engineer

Job Description

The Mechanical Engineer will design, fabricate, test, and deploy prototypes for counter-unmanned aircraft systems (cUAS) technology that directly contribute to next-generation airspace defense solutions. You will own mechanical designs from concept through production release, collaborating closely with electrical, software, systems, manufacturing, and product teams to deliver rugged, reliable hardware deployed in demanding real-world environments.

Responsibilities

• Design and develop mechanical components, assemblies, and enclosures for advanced airspace defense systems.
• Drive product development activities from initial concept generation through testing, validation, and manufacturing release.
• Create detailed 3D CAD models, engineering drawings, and design documentation using SolidWorks, Fusion 360, AutoCAD, or similar tools.
• Design a wide range of hardware including sheet metal components, welded structures, machined parts, injection molded components, and environmental enclosures.
• Build, assemble, and evaluate prototype hardware to validate design concepts and overall system performance.
• Develop and execute test plans to assess functionality, durability, and environmental reliability of mechanical designs.
• Collaborate cross-functionally with electrical engineers, systems engineers, product managers, manufacturing partners, and field teams to ensure cohesive system designs.
• Support system integration efforts and actively contribute to design reviews throughout the product lifecycle.
• Identify technical risks early in the development process and implement creative, practical solutions to complex engineering challenges.
• Maintain thorough documentation, specifications, and engineering change records to support traceability and quality.
• Contribute to continuous improvement initiatives focused on product quality, manufacturability, and cost optimization.
• Allocate approximately 30% of your time to CAD design and documentation, 30% to cross-functional collaboration and engineering reviews, 30% to hands-on prototyping, fabrication, testing, and validation, and 10% to rapid-response engineering support and problem solving.

Essential Skills

• Bachelor's degree in Mechanical Engineering or a closely related engineering discipline.
• 8+ years of professional mechanical engineering experience.
• Proficiency with CAD software such as SolidWorks, AutoCAD, Fusion 360, or similar platforms.
• Demonstrated experience creating engineering drawings and comprehensive design documentation.
• Strong experience in fabrication, testing, prototyping, and new product development.
• Ability to interpret and apply GD&T (Geometric Dimensioning and Tolerancing) in mechanical designs.
• Eligibility to obtain and maintain US Secret Clearance.
• Ability to travel up to 10% of the time.

Additional Skills & Qualifications

• Experience designing and releasing mechanical products into production environments.
• Hands-on prototyping experience using fabrication tools, machine shop equipment, or 3D printers.
• Experience with sheet metal design, weldments, machined components, injection molded plastics, and ruggedized enclosures.
• Familiarity with embedded systems, microcontrollers, or electromechanical systems.
• Experience designing for harsh environmental conditions and outdoor hardware applications.
• Knowledge of shock, vibration, thermal management, EMI/EMC, and environmental sealing considerations.
• Experience working on military, aerospace, defense, industrial, robotics, or outdoor hardware systems.
• Familiarity with MIL-STDs and environmental qualification testing processes.
• Experience using FEA, CFD, or other simulation tools to support design validation and optimization.
• Comfort working with advanced cUAS technologies that support military and public safety applications, including major global events and complex operational environments.
