SES Satellites
SES is a global space solutions company delivering resilient satellite connectivity and high-quality video content through an integrated multi-orbit network of ~120 GEO and MEO satellites.
Programme Description
meoSphere is SES’s next-generation Medium Earth Orbit (MEO) satellite constellation, designed to deliver secure connectivity services to government agencies, enterprises, and commercial customers. It will also provide high-speed broadband internet to eliminate global connectivity dead zones.
To accelerate development timelines, reduce costs, and ensure quality, SES is internalizing a critical segment of the satellite supply chain: the final integration of partner satellite platforms with SES’s software-defined payloads, all within a cutting-edge manufacturing and test facility.
Role Description
The System Integration &amp; Test (SI&amp;T) team is responsible for the integration, verification, validation, and end-to-end testing of the meoSphere System of Systems, encompassing spacecraft, ground systems, terminals, networks, software, and operational processes. The team ensures that system elements interoperate as intended and that end-to-end capabilities meet program and operational requirements.
As a Senior Engineer, you will lead and deliver system integration, verification, validation, and test activities across one or more of the following areas: Mission Test &amp; Pathfinder Integration, Systems Verification &amp; Validation, or Test Infrastructure &amp; Automation. Working across multiple engineering domains, you will develop test solutions, define and execute test activities, investigate technical issues, verify system requirements, and support major program milestones from system integration through operational readiness.
The role requires strong technical judgment, hands-on problem solving, and the ability to independently deliver complex technical work in a fast-paced engineering environment.
