We bring together technologies and industries, alongside the contributions of diverse individuals who are empowered by an intentional workplace culture, to solve problems better and faster.


As a Electrical Design Engineer, you will be responsible for the development, integration, and validation of electrical routing, wiring harnesses, and associated installation hardware used in land-based defence platforms, including gearboxes, drivetrains, and mechanical transmission systems. The role required strong understanding of electrical distribution, 3D CAD design, military-grade standards and cross-functional collaboration with mechanical, system and manufacturing teams.

Key Responsibilities:

Design and model electrical routing paths within complex gearbox and drivetrain assemblies Create 3D harness design using CAD tools (e.g. Solid Edge electrical, NX, Solid works) Develop harness schematics connector table, splice documentation and BOMS Collaboration with gearbox and mechanical subsystems engineers to route cabling through high-vibration, high-temperature, or constrained environments Perform interface definition for brackets, clamps, grommets and shielding solution Apply MIL-STD, DEF-STAN, and other relevant defence electrical design standards Ensure EMC/EMI integrity, environmental sealing, and survivability under shock, vibration. Produce engineering drawings, harness manufacturing packs, and installation instructions Support prototype builds, integration testing, and root-cause investigations

We are known for our extraordinary people who make the impossible possible every day. Questians are driven by hunger, humility, and aspiration. We believe that our company culture is the key to our ability to make a true difference in every industry we reach.
