Senior Piping Design Engineer

Company Overview D&M is a leader in the defense industry, specializing in the manufacturing and supply of ammunition and propellant solutions. We serve a global client base and maintain an extensive network of international suppliers to deliver high-quality, mission-critical products and systems.

Job Summary We are seeking a highly experienced Senior Piping Design Engineer to join our engineering team as a hands-on individual contributor. In this role, you will personally develop detailed 3D piping models and P&ID diagrams for factory installation projects involving both in-house engineered systems and procured equipment. You will integrate process piping, electrical conduit, plumbing/utilities, and controls elements while clearly defining battery limits for clients. This senior-level position requires strong technical execution with minimal support — you will perform the modeling, diagramming, and integration work directly. Some domestic and international travel will be required.

Key Responsibilities

• Independently create and maintain detailed 3D piping models in SolidWorks, including routing for process piping, electrical conduit, and standard plumbing/utility systems.
• Develop, review, and update Piping and Instrumentation Diagrams (P&IDs) to accurately define process flows, equipment integration, instrumentation, controls, and battery limits for client factory installation projects.
• Integrate in-house developed systems as well as procured third-party equipment into overall plant designs, ensuring compatibility, constructability, and proper interface points.
• Incorporate controls elements (instrumentation, valves, and automation tie-ins) into both 3D models and P&IDs.
• Perform clash detection, design reviews, and constructability assessments directly within the SolidWorks environment.
• Generate detailed drawings, isometrics, material take-offs, and technical documentation for fabrication, installation, and client deliverables.
• Collaborate with project managers, manufacturing, and other engineering disciplines to resolve design issues and optimize system layouts for international projects.
• Adapt designs to varying international client specifications, site conditions, and regulatory requirements.
• Travel occasionally (approximately 15-30%) for site visits, supplier coordination, client meetings, or factory installations, both domestically and internationally.

Requirements

• Bachelor’s degree in Mechanical Engineering, Chemical Engineering, or a closely related field (or equivalent combination of education and extensive experience).
• 15–20+ years of progressive, hands-on experience in piping design and engineering for industrial or manufacturing facilities, with significant expertise in 3D modeling and P&ID development.
• Advanced proficiency in SolidWorks for 3D piping modeling and routing (including process piping, electrical conduit, and utilities). Experience with SolidWorks P&ID or schematic tools is a strong plus.
• Solid understanding of piping standards, codes, and best practices for industrial process, utility, and plumbing systems.
• Demonstrated ability to define battery limits and clearly delineate scope/interfaces between in-house systems, procured equipment, and client facilities.
• Experience integrating controls and instrumentation into piping designs and P&IDs.
• Strong problem-solving skills and the ability to execute complex design work independently as an individual contributor.
• Excellent verbal and written communication skills, with the ability to produce clear technical documentation and presentations for internal teams and international clients.
• Willingness and ability to travel domestically and internationally (valid passport required).
• U.S. Citizenship required due to ITAR/EAR regulations governing the defense industry.

Preferred Qualifications

• Prior experience in the defense, aerospace, chemical, or energetics (ammunition/propellant) manufacturing sectors.
• Familiarity with defense industry regulations, safety standards, and export compliance (ITAR/EAR).
• Knowledge of international engineering codes and practices.
• Experience with additional plant design tools or SolidWorks add-ins for piping/plant layout.
• Professional Engineer (PE) license or equivalent certification is a plus.

What We Offer

• Competitive salary commensurate with experience and a comprehensive benefits package (health, dental, vision, 401(k), etc.).
• Opportunities for professional development and career growth within a growing defense technology company.
• Collaborative environment focused on innovation and supporting critical national security programs.
• [Add any additional perks, PTO, relocation assistance, or other details here.]
