  • 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

  • 8+ years of professional mechanical engineering experience.

  • Proficiency with CAD software such as SolidWorks, AutoCAD, Fusion 360, or similar platforms.

  • Strong background 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 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.
