(Senior) Engineer, System Integration & Test, meoSphere

SES•Chicago, IL

19d•Hybrid

About The Position

The System Integration & Test (SI&T) team integrates, verifies, validates, and conducts end-to-end testing of the meoSphere System of Systems, including spacecraft, ground systems, terminals, networks, software, and operational processes. The team ensures that system elements interoperate as intended and that end-to-end capabilities satisfy program and operational requirements. The Senior Engineer leads and delivers system integration, verification, validation, and test activities in one or more of these areas: Mission Test & Pathfinder Integration, Systems Verification & Validation, or Test Infrastructure & Automation. Working across engineering domains, the role develops test solutions, defines and executes test activities, investigates technical issues, verifies system requirements, and supports program milestones from system integration through operational readiness. The position requires strong technical judgment, hands-on problem solving, and the ability to independently deliver complex technical work in a fast-paced engineering environment. The role supports SES’s meoSphere next-generation Medium Earth Orbit satellite constellation, which is designed to provide secure connectivity to government agencies, enterprises, and commercial customers, as well as high-speed broadband intended to eliminate global connectivity dead zones. SES is internalizing final integration of partner satellite platforms with its software-defined payloads in a manufacturing and test facility. In the first year, the engineer is expected to become an independent SI&T contributor and deliver assigned technical outputs supporting program milestones and readiness objectives. Work may include integration, verification, validation, mission testing, test automation, controlled procedures and configurations, test campaign execution and evidence, technical analysis and reports, anomaly disposition, and improvements to test environments or capabilities. The candidate must be eligible for a SECRET security clearance under applicable national regulations or EU/ESA/NATO equivalents, work 60% onsite, and travel as required for project realization. Responsibilities may evolve with business needs.
