Mechanical Engineer

N4 Solutions, LLC offers our public and private sector clients the collective intellectual knowledge, expertise, and experience of our company and associates to help our customers evaluate, collaborate, innovate, and create business, technology, and scientific solutions that enable them to accomplish their mission and achieve organizational objectives. With the growth of the company, we are seeking a highly motivated and hard-working mechanical engineering professional to join our team.

The successful candidate will work in a high-paced and rewarding work environment.
JOB DESCRIPTION/DUTIES:The Mechanical Engineer will serve as a senior Research and Development (R&D) technical leader supporting NRL, with a primary focus on mechanical engineering, structural integrity, and environmental testing of Navy materials and components. The position will lead and coordinate structural integrity testing of metallic alloys, non-metallic materials, bearings, and other components to evaluate durability, fatigue, static and dynamic stiffness, and related performance characteristics.

The successful candidate will manage complex R&D activities from test planning and experimental design through test execution, data analysis, technical reporting, and fleet-relevant technology transition while ensuring technical quality and alignment with Navy mission and sponsored-program objectives.

• Provide senior R&D management and technical leadership for mechanical engineering, structural integrity, materials performance, and component testing programs supporting Navy ships, submarines, aircraft, marine structures, and other war fighting platforms.
• Lead the planning, development, and execution of structural integrity tests on metallic alloys, non-metallic materials, bearings, and other Navy-relevant components and systems.
• Develop and review test plans that measure durability, fatigue, static stiffness, dynamic stiffness, mechanical performance, and other properties necessary to evaluate material and component suitability for Navy applications.
• Incorporate Navy-relevant environmental parameters into test programs, including exposure to natural seawater, periodic sea spray, atmospheric conditions, temperature, load, cycling, and other operational variables that may affect material or component performance.
• Direct fundamental and applied studies evaluating the effects of structural material selection, fabrication techniques, heat treatment, welding, and mechanical processes on performance, operation, and degradation.
• Plan and oversee mechanical and environmental test programs designed to characterize material properties, degradation mechanisms, durability, fatigue behavior, and performance under representative naval operating conditions.
• Evaluate physio-mechanical effects associated with bonding, fastening, adhesives, additive manufacturing, surface modification or enhancement, wear, environmental exposure, stress and strain, inhibitors or additives, and crevice geometry as applicable to assigned R&D programs.
• Develop experimental designs, instrumentation approaches, data requirements, quality controls, acceptance criteria, and test procedures to ensure repeatable, defensible, and technically sound mechanical test results.
• Oversee test setup, instrumentation validation, data acquisition, monitoring, and control activities to assure test integrity and reliable measurement of structural and mechanical performance.
• Lead analysis and interpretation of mechanical test data to identify failure mechanisms, performance trends, degradation behavior, service-life implications, and opportunities for material or design improvement.
• Support the design, procurement, fabrication, construction, and evaluation of experimental platforms, test beds, machinery, piping systems, mockups, fixtures, and simulated environments required for mechanical and structural testing.
• Use analytical, statistical, modeling, and engineering software to evaluate test data, compare material and component performance, support numerical analyses, and develop technically defensible conclusions and recommendations.
• Support laboratory, waterfront, shipboard, field, and other Navy-relevant test and evaluation activities involving materials, components, structures, machinery, and environmental exposure.
• Plan and support technology demonstrations, proof-of-concept evaluations, and transition activities for materials, components, structural systems, and mechanical technologies intended to improve readiness,…
