Satellite Systems Engineer - Space Payload&In-Orbit Ops, Lausanne

An opportunity has arisen for a Satellite Systems Engineer to join a multidisciplinary team working on next-generation satellite communications architectures.

This role focuses on the design, analysis, and development of advanced space payload systems for telecommunications applications, supporting complex satellite missions across LEO, MEO, GEO, and highly elliptical orbits. You will contribute to cutting‑edge R&D programmes spanning system definition through to in‑orbit commissioning.

You will work at the forefront of satellite communications system design, with responsibility across mission analysis, system architecture, payload design support, and technical trade‑offs. The role requires a strong understanding of spaceborne communication systems and the ability to contribute across the full development lifecycle, from requirements definition through to integration and operational support.

Key Responsibilities

Lead mission analysis activities and translate system requirements into lower-level specifications

Define system SWaP‑C (Size, Weight, Power, Cost) constraints and manage cross‑domain interface definitions (RF, digital, electrical, optical, mechanical, thermal)

Lead architectural trade studies, link budget analysis, and system‑level design decisions

Support and challenge external contractors and subcontractors on technical delivery

Assist with reliability analysis and system‑level simulation activities

Support spacecraft and payload qualification activities, including platform and component selection input

Contribute to programme planning, technical reporting, and customer‑facing programme discussions

Support integration, test campaigns, launch preparation, and in‑orbit commissioning activities

Participate in design reviews, manufacturing oversight, qualification reviews, and progress reporting

Essential Skills&Experience

Master’s or PhD in Engineering (e.g. Satellite Communications, Telecommunications, Electronics, or Digital Systems)

8–10 years’ experience in satellite or space systems engineering

Strong background in satellite communications and payload architectures across LEO/MEO/GEO/HEO missions

Experience with phased array antenna systems and digital beamforming
