Mechanical Design Engineer
About the Role
Imagine standing at the edge of aerospace innovation, designing mechanisms that need to move faster, react quicker, and perform reliably in extreme environments.
This is not just about designing components. You will be helping develop the mechanical systems behind next-generation UAV technology, where every calculation, tolerance, assembly, and design decision directly contributes to speed, autonomy, precision, and reliability.
Our client is a fast-growing aerospace and defence technology company developing advanced Unmanned Aerial Vehicle systems for mission-critical applications. Their technology is designed to support modern defence operations through speed, precision, and cost-effective innovation.
This is an opportunity to work on complex, high-performance aerospace systems and contribute to the future of flight.
What You'll Do
Create detailed CAD designs, including part modelling, assemblies, drafting, and technical drawings
Work with Siemens NX or similar CAD tools
Apply strong mechanical design principles and engineering fundamentals




Use Geometric Dimensioning and Tolerancing, GD&T;, in design work
Design with manufacturing and assembly in mind, applying DFM and DFA principles
Use engineering analysis tools such as FEA/FEM where required
Work with PLM systems such as Teamcenter
Produce clear technical documentation
Collaborate cross-functionally with engineering, production, and supplier teams
Manage multiple design activities and projects in a fast-paced environment
Support the development of precision mechanical systems across the full product lifecycle
What We're Looking For
Bachelor's or Master's degree in Mechanical Engineering
3+ years of mechanical design experience in a precision engineering environment
Strong experience with CAD design, ideally Siemens NX or similar
Good understanding of mechanical design for high-performance or safety-critical systems
Experience with GD&T;, DFM, DFA, and technical documentati
