About The Position

SES Space & Defense is seeking a Senior Systems Engineer – Ground Systems & Advanced Concepts to support strategic franchise initiatives focused on developing and maturing innovative space-based capabilities and services. The position will focus primarily on the architecture, integration, and delivery of ground-segment capabilities supporting SES mPOWER-based satellite relay services, multi-orbit architectures, intersatellite links, and hosted payload missions. This role bridges concept development and execution, working with franchise teams, Business Development, engineering organizations, customers, and technology partners to translate emerging concepts into executable ground architectures, proofs of concept (POCs), demonstrations, study contracts, and ultimately operational capabilities.

Requirements

Bachelor's degree in a relevant engineering or technical discipline, or equivalent education and directly applicable experience.
7+ years of relevant Systems Engineering experience developing, integrating, or delivering complex technical systems.
Experience developing or integrating satellite, ground, communications, network, or mission systems.
Experience developing ground-segment or end-to-end communications architectures.
Experience with Model-Based Systems Engineering (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 associated RF equipment at both the hub/gateway and remote/user-terminal sides of the network.
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.

Nice To Haves

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, Satellite Operations Centers (SOCs), Network Operations Centers (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 Department of Defense communications programs and/or the ability to obtain a U.S. Government security 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 Interface Control Documents (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 associated 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 supporting system development and customer deliverables.
Develop and execute system integration and test plans, procedures, verification activities, and test reports supporting POCs, demonstrations, and operational capabilities.
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 technical deliverables.
Support franchise and Business Development teams during customer engagements and coordinate multidisciplinary engineering teams, vendors, and partners to transition successful concepts toward operational services.
