(Senior) Engineer, Systems Engineering, meoSphere

(Senior) Engineer, Systems Engineering, meoSphere The job responsibilities outlined in this document are not exhaustive and may evolve over time and be reviewed according to business needs. 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 SUMMARY The Senior Systems Engineer provides technical expertise in the architecture, development, integration, and validation of the meoSphere satellite constellation and its end-to-end communications network. The role supports system level engineering activities across the network ecosystem, including the communications ground segment, network orchestration systems, 5G core network integration, and satellite constellation. Reporting to the Chief Systems Engineer, the Senior Systems Engineer contributes to the successful delivery of programme objectives by applying systems engineering best practices within a modern "new space" development environment. The role works closely with multidisciplinary engineering teams to support system architecture, requirements management, integration activities, and verification efforts, while balancing technical rigor with development agility. The successful candidate will contribute to the implementation of agile systems engineering approaches that enable iterative development, rapid testing, and continuous improvement, while ensuring alignment with programme requirements, schedule, cost, and performance objectives. PRIMARY RESPONSIBILITIES / KEY RESULT AREAS System Architecture & Engineering Contribute to the development and maintenance of the end-to-end architecture for the meoSphere network, including the space segment, ground segment, network orchestration platforms, and 5G core integration. Support the development of system requirements, operational concepts (CONOPS), and performance budgets. Participate in architectural trade studies related to constellation design, payload capabilities, network architecture, and ground infrastructure. Support major system engineering review preparation and execution (e.g SRR, PDR, CDR, TRR, ORR milestones). Ensure engineering solutions align with system scalability, resilience, service performance, and operational requirements. Agile Systems Engineering & Development Apply agile systems engineering principles to support iterative development and continuous improvement. Participate in the integration of…
