CAD Draftsman

About POWERTECH

POWERTECH is a center of excellence for propulsion technologies, specializing in the design, engineering, and manufacturing of combustion engines, expendable turbojet engines, and turbofan engines for a wide range of aerospace, defence, and autonomous applications, including fixed- and rotary-wing UAVs and other advanced platforms.

Role Overview

You will be responsible for creating, modifying, and managing 3D/2D CAD models using SolidWorks, with a specific focus on high-precision mechanical components, and jet engines. A key part of this role is performing tolerance stack-up analysis to ensure manufacturability, assembly fit, and reliable product performance, Owning the CAD for large assemblies, managing and tracking changes, and creating drawings.

Key Responsibilities

• Develop detailed 3D models and fully-defined 2D drawings using SolidWorks.
• Execute tolerance stack-up analyses (linear, worst-case, RSS) to validate designs and ensure robust assembly.
• Apply GD&T (ASME Y14.5) principles to drawings.
• Create BOMs, drawing packages, and revision-controlled documentation.
• Collaborate with design, manufacturing, and quality teams to optimize part geometry and tolerances.
• Update designs based on engineering changes, test results, and supplier feedback.
• Prepare design review content and support engineering discussions.
• Ensure CAD data is clean, standardized, and follows drafting practices.
  
  

• Diploma or Bachelor’s degree in Mechanical Engineering or similar.
• 5 years of experience as CAD draftsman
• Strong proficiency in SolidWorks 3D modelling and 2D drafting.
• Hands-on experience with tolerance stack-up analysis and understanding of GD&T.
• Ability to interpret engineering drawings, manufacturing methods, and material properties.
• Good understanding of DFM/DFA principles.
• Strong attention to detail and structured documentation habits.
  
  

• Experience with PLM systems (SolidWorks PLM, Windchill, or similar).
• Familiarity with machining, sheet metal, or plastic part design.
• Basic simulation knowledge
• Understanding of precision mechanical assemblies or rotating machinery
  
  

• Strong communication skills for cross-functional collaboration.
• Ability to work independently with minimal supervision.
• Problem-solving mindset with focus on accuracy and reliability.
• Good time management and ability to meet tight deadlines
