The ideal candidate will have strong hands-on experience in mechanical and electromechanical product design, product development, and engineering problem-solving. Experience designing automotive electrical connectors, precision plastic housings, electronic components, or similar electromechanical assemblies is highly preferred.

This role involves supporting the full product development lifecycle, from initial concept and detailed design through prototyping, validation, and manufacturing launch.

Key Responsibilities

• Design and develop mechanical and electromechanical components, including electrical connectors, precision plastic housings, and related assemblies.
• Create and modify 3D CAD models, engineering drawings, and product specifications.
• Perform GD&T, dimensional tolerance analysis, and DFM/DFA.
• Support product development from concept through prototyping, validation, and production release.
• Conduct design reviews, DFMEA, engineering calculations, and root-cause analysis.
• Evaluate materials, mechanical performance, dimensional requirements, and manufacturing feasibility.
• Collaborate with tooling, manufacturing, quality, and cross-functional engineering teams.
• Troubleshoot product fit, function, assembly, and reliability issues.
• Support product testing, design verification, engineering changes, and manufacturing launch activities.

Required Qualifications

• 7+ years of mechanical or electromechanical product design and development experience preferred.
• Bachelor's degree in Mechanical Engineering, Electrical Engineering, or a related field preferred.
• Hands-on experience designing mechanical or electromechanical products and components.
• Proficiency with Siemens NX, Creo, SolidWorks, or CATIA.
• Strong knowledge of GD&T, tolerance stack-up analysis, engineering drawings, and DFM/DFA.
• Familiarity with injection-molded plastics, metal-stamped components, and precision manufacturing processes.
• Experience supporting product validation, testing, and manufacturing launch.
• Strong engineering problem-solving and cross-functional collaboration skills.
• Must currently reside in Michigan and be available to work onsite in the Greater Detroit area.

Preferred Qualifications

• Direct experience designing automotive electrical connectors, connector housings, or terminals.
• Knowledge of automotive wire harness connections, sealing systems, and retention mechanisms.
• Experience with DFMEA, DVP&R, FEA, APQP, or PPAP.
• Familiarity with engineering thermoplastics such as PBT, LCP, PPS, and PA66.
• Experience with high-voltage, high-current, or signal connector products.
• Background in automotive electrical/electronic component manufacturing.
