Job summary

SES Space & Defense is seeking a Senior Systems Engineer to lead ground-system architectures and end-to-end integration for mPOWER and multi-orbit concepts. You’ll craft requirements, interface control documents, and verification strategies while coordinating across hardware, software, RF, and network teams.

The role emphasizes MBSE, system integration, and customer-facing demonstrations. You will engage with franchise teams and partners to translate concepts into executable ground architectures

Qualifications

• Bachelor's degree in engineering or related field.
• 7+ years of Systems Engineering experience.
• Experience developing or integrating satellite, ground, communications, network, or mission systems.
• Experience developing ground-segment or end-to-end communications architectures.
• Experience with MBSE and requirements development, management, traceability, and verification.
• Experience developing and executing system integration and test plans, procedures, and test reports.
• Broad understanding of satellite communications and the interaction between space, ground, network, and user segments.
• Working knowledge of satellite ground infrastructure, networking, ground command and control, mission planning, or related systems.
• Familiarity with satellite communications modems, waveforms, and RF equipment at hub/gateway and user-terminal sides.
• Ability to translate emerging technical concepts into practical architectures and coordinate integration across hardware, software, networks, and operational capabilities.
• Strong written, verbal, analytical, and technical presentation skills.
• Must meet U.S. Person requirements.
• Experience with SES mPOWER and multi-orbit satellite architectures preferred.
• Familiarity with the SES mPOWER ground control software suite and associated operational architecture preferred.
• Familiarity with intersatellite links, satellite relay services, hosted payload integration, and UHF SATCOM preferred.
• Experience with satellite ground stations, gateways, teleports, SOCs, NOCs, or Ground Command and Control systems preferred.
• Experience executing POCs, demonstrations, prototypes, or Government-funded studies preferred.
• Familiarity with digitization of communications and ground-system functions, cloud architectures, APIs, automation, and orchestration preferred.
• Experience supporting U.S. Government or DoD programs and/or ability to obtain clearance preferred.

Responsibilities

• Develop ground-segment and end-to-end architectures supporting strategic franchise initiatives, including SES mPOWER-based satellite relay services, intersatellite links, hosted payloads, and UHF capabilities.
• Translate space-segment concepts into executable ground architectures, interfaces, operational concepts, and integration approaches.
• Develop and manage system requirements, interfaces and ICDs, architecture models, and verification approaches using MBSE and requirements management practices.
• Define and integrate ground infrastructure including gateways, ground stations, command and control, mission planning, terrestrial networks, cloud environments, customer interfaces, modems, waveforms, and RF equipment.
• Leverage existing SES infrastructure, networks, software platforms, and operational capabilities to accelerate new concepts and services.
• Develop and maintain technical specifications, architecture documentation, engineering analyses, trade studies, and technical reports.
• Develop and execute system integration and test plans, procedures, verification activities, and test reports.
• Plan and support the integration and execution of POCs, prototypes, technology demonstrations, and customer demonstrations.
• Provide Systems Engineering support to study contracts, including requirements analysis, architecture development, feasibility assessments, and deliverables.
• Support franchise and Business Development teams during customer engagements and coordinate multidisciplinary engineering teams, vendors, and partners to transition concepts toward operational services.
