Senior Mechanical Engineer

Overview

In this role you own mechanical design for avionics and payload installations within a fast-paced aerospace and defence team. You’ll take hardware from concept through qualification to production and collaborate across disciplines to deliver flight-ready solutions. The work spans mechanical, thermal and electrical interfaces, with rapid iteration from CAD to flying hardware. You’ll influence design choices, support testing, and mentor junior engineers while contributing to mission-critical systems.
