Senior Electrical Engineer

Overview

As a Senior Electrical Engineer in London, you will design and integrate spacecraft electrical subsystems for a major space mission. You will own electrical architecture and ensure high reliability in orbital environments, working closely with avionics, payloads, and onboard computers. You’ll shape power distribution, harness design, and data handling to support mission success. This role offers hands-on impact in a global engineering team at ALTEN, with a clear path for growth and security clearance readiness.
