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 documentation
Exposure to FEA/FEM tools
Experience working with technical suppliers to ensure design requirements are met
Experience supporting products across the full lifecycle
Aerospace, defence, or military-spec product experience would be highly advantageous

Who You Are
You enjoy solving complex engineering challenges and thrive in a fast-moving technical environment. You are practical, curious, and comfortable working closely with other engineering disciplines to bring ideas from concept through to real-world application.
You are not afraid to challenge conventional design thinking, test ideas, and refine solutions until they meet the required level of performance, reliability, and manufacturability.

Why Join?
Work on cutting-edge aerospace and defence technology
Contribute to next-generation UAV systems
Collaborate with highly skilled engineers from across the world
Join a fast-paced, high-growth environment
See your work have a real impact on the future of flight
