Senior Mechanical Systems Engineer - Design, Analysis, and Integration (Remote)

Collins Aerospace is a leader in aerospace and defense solutions, and they are seeking a Senior Mechanical Systems Engineer to design and deliver complex mechanical solutions. This role involves operating across the full engineering lifecycle, translating requirements into hardware through design, analysis, and system-level thinking.

Responsibilities:

• Execute integrated mechanical design and analysis activities, ensuring alignment across functional and performance requirements, physical architecture and packaging constraints, and manufacturability, reliability, and lifecycle considerations
• Develop and mature concepts, layouts, and detailed designs for mechanical systems and components, including rotating machinery, actuation systems, mechanical control elements, electro-mechanical assemblies, and electronics packaging, with exposure to maritime and undersea systems as applicable
• Perform and support multi-disciplinary analysis (structural, thermal, vibration, fluid, and system-level modeling), including generating loads, defining boundary conditions, building models, and correlating analytical results with test data and field performance
• Translate system requirements into physical architectures and executable design solutions, including space claim definition, system layout, interface definition, and cross-domain integration across mechanical and electrical systems, supported by early-stage trade studies and concept evaluations
• Support early-phase engineering efforts through concept definition, feasibility assessments, development of preliminary models and layouts, and providing engineering inputs to scope, cost, and schedule planning
• Develop and maintain complete technical data packages, including 3D models, drawings, specifications, and analysis artifacts, ensuring accuracy, completeness, and configuration control
• Define and execute development, qualification, and acceptance testing, ensuring alignment with system requirements and validation of analytical predictions
• Implement design changes across the product lifecycle while maintaining configuration control, traceability, and alignment with program objectives
• Support supplier engagement through technical coordination, component qualification, and resolution of design, manufacturing, or performance-related issues
• Participate in or lead root cause and corrective action investigations (RRCCA), integrating insights from design, analysis, manufacturing, and field data to drive resolution and continuous improvement

Requirements:

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 5 years prior relevant experience or an Advanced Degree in a related field and minimum 3 years of experience
• Demonstrated experience in two or more of the following areas: mechanical design across the full product lifecycle (concept through production); multi-disciplinary engineering analysis (FEA, thermal, fluid, or system-level modeling); and system integration and packaging of electro-mechanical systems
• Prior experience using NX or a comparable CAD tool (minimum 3 years)
• Prior experience using PLM systems such as Teamcenter or equivalent (minimum 3 years)
• Experience utilizing engineering analysis tools such as ANSYS, Simulink, Mathcad, or equivalent
• Experience in defense, aerospace, or maritime/undersea systems
• Experience performing trade studies, concept evaluations, or early-phase engineering development
• Experience integrating design and analysis into cohesive system solutions
• Familiarity with AS9100, configuration management, and design release processes
• Master's degree in Mechanical Engineering or related field
