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.

Required Qualifications

• 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.

Preferred Skills

• 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

Soft Skills

• 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
