United States Bullet Proofing, Inc. (USBP) is seeking a Design Engineer to support the development, refinement, and continuous improvement of aluminum door and window systems. This role owns designs from concept through production release, with an emphasis on physical security performance – including ballistic resistance, forced entry resistance, and blast mitigation. The ideal candidate combines strong mechanical design fundamentals with hands-on knowledge of door hardware, laminated glass layups, and manufacturing processes, and is comfortable coordinating across internal teams, outside test labs, and partner engineering firms. Key Responsibilities • Design, detail, and document aluminum door and window assemblies and components using 3D CAD software, producing manufacturing-ready drawings and models. • Develop and refine products for physical security applications, including ballistic-resistant, forced-entry resistant, and blast-mitigating configurations. • Select and specify door hardware and laminated glass layups to meet performance, code, and customer requirements. • Coordinate with internal stakeholders (engineering, production, quality, sales) and external partners – test labs and outside engineering firms – to plan, execute, and interpret product testing (ballistic, forced entry, blast, and related certifications). • Continuously evaluate existing products to identify opportunities for immediate improvements and next generation redesigns. • Develop, document, and maintain internal design and engineering standards, and ensure the team follows them consistently. • Own document and revision control for drawings, specifications, and test records, ensuring accuracy and traceability throughout the product lifecycle. • Maintain organized records of product development and testing documentation, including test reports, certifications, and design history files. • Support root-cause analysis and corrective actions for design- or manufacturing-related issues identified in production or the field. • Communicate design status, risks, and technical findings clearly to engineering leadership and cross functional teams. Education • Minimum: Associate degree in Engineering or a related discipline. • Preferred: Bachelor of Engineering (BE) or Bachelor of Science (BS) in Engineering. Required Qualifications • Experience designing or engineering products for manufacturing, with direct exposure to aluminum door and window systems. • Working knowledge of AutoCAD Inventor or SolidWorks (or comparable 3D CAD platform). • Strong written and verbal communication skills, with the ability to work effectively with internal stakeholders, test labs, and outside engineering firms. • Highly organized, with strong attention to detail and a disciplined approach to document and revision control. • Self-starter who takes initiative to learn new codes, standards, materials, and testing methods without prompting. • Ability to manage multiple concurrent projects and shifting priorities in a fast-paced manufacturing environment. • Minimum 5 plus years of related experience. Preferred Qualifications • Experience with physical security performance requirements: ballistics, forced entry, and blast resistance. • Familiarity with door hardware selection and laminated glass layup design. • Experience working with independent test labs and understanding of relevant test standards and certification processes. • Prior experience developing or maintaining internal engineering standards or design guidelines. What We Offer United States Bullet Proofing, Inc. offers the opportunity to work on mission-critical security products, a collaborative engineering environment, and the chance to shape both current products and next-generation designs from the ground up. Location & Travel Upper Marlboro, MD. Remote work may be available for qualified candidates. Travel to test labs is required when needed to support and observe ballistic, forced entry, and blast testing.
