Job title: Mechanical Design Engineer
Department: Engineering
Reports to: Design Engineering Manager
Location: [City], [office, branch or site]
About the role
A Mechanical Design Engineer designs mechanical parts, assemblies and machines. They model in 3D CAD, apply material and manufacturing knowledge, do basic strength and fit calculations, and produce production drawings with tolerances. The role sits in product or machine design. A good Mechanical Design Engineer designs parts that are strong, light and easy to make, applies GD&T correctly, and reduces cost and assembly problems before anything reaches the shop.
Key responsibilities
- Model mechanical parts and assemblies in 3D CAD from the requirements.
- Do strength, stiffness and fit calculations for the components.
- Apply GD&T and tolerances for correct function and assembly.
- Select materials and manufacturing processes suited to each part.
- Prepare production drawings, bills of material and part specifications.
- Design for manufacturing and assembly to reduce cost and rework.
- Build and check prototypes and update the design from findings.
- Coordinate with vendors on machined, cast or fabricated parts.
- Incorporate checker comments and revise the drawings and models accordingly.
Requirements
- Bachelor's degree or diploma in mechanical engineering
- Training in a 3D CAD tool
- Knowledge of manufacturing processes
- Fresher or up to 2 years in mechanical design
KRAs and KPIs for a Mechanical Design Engineer
Key result areas for the appraisal form, each with a KPI you can measure every month or quarter.
| Key result area | How to measure it |
|---|---|
| Design quality | Parts released with correct fit and function, no assembly rework |
| Manufacturability | Designs made without deviation requests from the shop |
| Tolerance control | GD&T applied correctly with no scrap from wrong tolerances |
| Cost | Part cost kept within the design target |
| Deliverables | Drawings and BOM released on the dated schedule |
| Prototype | Prototypes pass fit and function check on first build |
Skills and tools
Tools used day to day: SolidWorks or Creo, AutoCAD, MS Excel, GD&T references, PDM system.

What does a Mechanical Design Engineer do?
A Mechanical Design Engineer designs mechanical parts, assemblies and machines. They model in 3D CAD, do strength and fit calculations, apply GD&T, select materials and processes, and prepare production drawings. They design for manufacturing and check prototypes. Their job is parts that are strong, cheap to make and easy to assemble.
What is the difference between a Mechanical Design Engineer and a Mechanical Engineer?
A Mechanical Design Engineer focuses on designing parts and machines in the design office. A Mechanical Engineer is a broader role that may cover maintenance, production, quality or design depending on the company. Design is one path a mechanical engineer can specialise in.
What qualifications does a Mechanical Design Engineer need?
A diploma or degree in mechanical engineering with training in a 3D CAD tool such as SolidWorks or Creo. Employers value knowledge of manufacturing processes, GD&T, material selection and basic strength calculation. Project work and internships strengthen a fresher profile.
