Senior Mechanical Systems Engineer; Defense Platforms

We are seeking an experienced Senior Mechanical Engineer to lead the design, development, integration, and validation of complex mechanical systems and vehicle platforms. This role is responsible for providing technical leadership across multidisciplinary engineering programs, supporting projects from concept development through prototype build, testing, and production implementation.

The successful candidate will bring strong mechanical engineering expertise, systems-level thinking, and a proven ability to guide technical decisions in a collaborative environment. This individual will work closely with customers, suppliers, manufacturing teams, and engineering disciplines to deliver innovative solutions while meeting performance, quality, cost, and schedule objectives.

This position is a senior technical role with responsibility for mentoring engineers and providing project-level technical leadership, but it does not include direct personnel management responsibilities.

• Lead the design and development of mechanical systems, assemblies, and components for advanced vehicle and product applications.
• Drive system-level engineering activities including requirements development, concept evaluation, detailed design, and validation.
• Oversee integration, assembly, and testing efforts for vehicle, subsystem, and component-level programs.
• Perform engineering analyses, trade studies, and design reviews to support informed technical decisions.
• Ensure designs meet performance, reliability, manufacturability, safety, and regulatory requirements.

• Support prototype builds and system integration activities throughout the product development lifecycle.
• Define and execute validation plans to verify system performance and functionality.
• Analyze test results and implement corrective actions when required.
• Troubleshoot mechanical and system-level issues during development and testing.
• Evaluate the impact of design changes on overall system performance and program objectives.

• Serve as a key technical liaison for customers, suppliers, and internal stakeholders.
• Present engineering concepts, design solutions, test results, and technical recommendations to both technical and non-technical audiences.
• Participate in customer reviews, project meetings, and milestone assessments.
• Assess technical feedback and determine impacts to product design, cost, timing, and risk.
• Collaborate with program management to support project planning and successful execution.

• Provide technical guidance and mentorship to project engineers and cross-functional teams.
• Lead engineering reviews, design evaluations, and technical problem-solving activities.
• Promote engineering best practices and adherence to established development processes.
• Support continuous improvement initiatives focused on product quality, efficiency, and customer satisfaction.
• Contribute to the growth and development of engineering capabilities across the organization.
• Utilize CAD software, Product Data Management (PDM) systems, and engineering analysis tools throughout the development process.
• Develop and maintain technical documentation including engineering reports, specifications, design packages, and test plans.
• Support configuration management and engineering change control processes.
• Ensure compliance with company engineering standards and industry best practices.

• Bachelor's degree in Mechanical Engineering or a closely related engineering field.
• 10+ years of professional mechanical engineering experience.
• Demonstrated success leading complex mechanical design and integration projects.
• Experience working at the vehicle, system, or subsystem level in a product development environment.
• Strong technical problem-solving and analytical skills.
• Excellent written, verbal, and presentation communication abilities.
• Experience working directly with customers and multidisciplinary engineering teams.
• Proficiency with Microsoft Office applications, including Word, Excel, and PowerPoint.

• Master's degree in Mechanical…
