Job Description

Senior Mechanical Designer 

Location: Raleigh, NC
Pay Rate: Based on Experience
Work Location: 100% Onsite

Position Overview

M Force Partners is seeking an experienced Senior Mechanical Designer to support the development of custom machinery, precision gearboxes, power transmission systems, and specialized mechanical test equipment. This position offers the opportunity to collaborate with an experienced engineering team on technically complex mechanical design projects.

The Senior Mechanical Designer will use advanced SolidWorks skills to transform engineering concepts, preliminary calculations, sketches, and technical requirements into detailed mechanical designs and manufacturing-ready documentation. This role requires practical knowledge of mechanical systems, precision rotating equipment, and complex machinery assemblies.

The ideal Senior Mechanical Designer has experience designing functional machinery and understands how mechanical components interact beyond the CAD modeling process. Candidates with experience designing powertrains, propulsion systems, transmissions, gearboxes, or gears are strongly encouraged to apply.

SolidWorks experience and U.S. citizenship are required. This position is 100% onsite in Raleigh, NC.

Key Responsibilities

• Develop complex 3D mechanical models, parts, and assemblies using SolidWorks

• Design custom machinery, precision gearboxes, rotating equipment, and specialized mechanical testing systems

• Translate engineering concepts, sketches, preliminary calculations, and technical discussions into functional mechanical designs

• Incorporate mechanical power transmission components, including gears, shafts, splines, bearings, seals, couplings, and housings

• Develop and refine mechanical assemblies while maintaining organized parametric models and design intent

• Evaluate mechanical layouts for fit, alignment, clearances, component interference, and assembly requirements

• Consider assembly sequencing, tool accessibility, equipment maintenance, and serviceability throughout the design process

• Apply Geometric Dimensioning and Tolerancing (GD&T), dimensional fits, and tolerance stack-up analysis to precision mechanical assemblies

• Prepare detailed manufacturing drawings, assembly drawings, Bills of Materials (BOMs), and supporting technical documentation

• Evaluate alternative mechanical design concepts and identify potential engineering challenges

• Identify missing technical information, component conflicts, manufacturing constraints, and assembly concerns

• Collaborate with senior engineers and mechanical designers throughout concept development, design refinement, and documentation

• Incorporate engineering feedback, updated calculations, and component changes into mechanical designs

• Ensure mechanical designs account for manufacturing methods, precision requirements, and equipment functionality

• Support machinery development from initial concept through manufacturing and assembly

Required Qualifications

• Extensive hands-on experience in mechanical design, machine design, or custom machinery development

• Advanced proficiency in SolidWorks is required, including parametric modeling, complex mechanical assemblies, and manufacturing drawings

• Demonstrated experience designing mechanical systems involving power transmission or precision rotating components

• Strong understanding of mechanical components, including gears, shafts, splines, bearings, seals, couplings, and housings

• Knowledge of bearing arrangements, shaft fits, retention methods, lubrication systems, sealing requirements, and mechanical alignment

• Experience applying GD&T, functional datums, dimensional tolerances, and tolerance stack-up analysis

• Ability to interpret engineering sketches, sectional views, preliminary calculations, and evolving design requirements

• Experience developing detailed mechanical drawings, assembly documentation, and Bills of Materials

• Strong understanding of mechanical assembly requirements, manufacturing processes, and precision machining considerations

• Ability to identify component interference, assembly limitations, clearance issues, and potential manufacturing challenges

• Strong three-dimensional visualization and mechanical problem-solving skills

• Ability to independently develop practical mechanical design solutions from incomplete engineering concepts

• Strong communication skills and ability to collaborate with experienced engineering professionals

• Ability to incorporate technical feedback and adjust designs as project requirements evolve

• Ability to demonstrate personal contributions to completed machinery designs or precision mechanical assemblies

• U.S. citizenship is required due to contractual requirements

• Ability to work 100% onsite in Raleigh, NC

Preferred Qualifications

• Experience designing mechanical powertrains and propulsion systems

• Experience designing transmissions, gearboxes, and gear assemblies

• Background in mechanical power transmission and precision rotating equipment

• Experience with custom machinery, machine tools, or specialized industrial equipment

• Experience designing spindle systems or high-speed rotating machinery

• Experience with dynamometers and mechanical testing equipment

• Experience developing precision mechanical assemblies involving complex rotating components

• Experience supporting machinery development from initial concept through manufacturing and assembly

• Experience collaborating with senior engineering teams on technically complex equipment designs
