Lead Satellite Systems Engineer in Bussigny

An opportunity has arisen for a Lead Satellite Systems Engineer to join a multidisciplinary team working on next-generation satellite communications architectures.This role focuses on the design, analysis, and development of advanced space payload systems for telecommunications applications, supporting complex satellite missions across LEO, MEO, GEO, and highly elliptical orbits. You will contribute to cutting‑edge R&D programmes spanning system definition through to in‑orbit commissioning.You will work at the forefront of satellite communications system design, with responsibility across mission analysis, system architecture, payload design support, and technical trade‑offs. The role requires a strong understanding of spaceborne communication systems and the ability to contribute across the full development lifecycle, from requirements definition through to integration and operational support.Key ResponsibilitiesLead mission analysis activities and translate system requirements into lower‑level specificationsDefine system SWaP-C (Size, Weight, Power, Cost) constraints and manage cross-domain interface definitions (RF, digital, electrical, optical, mechanical, thermal)Lead architectural trade studies, link budget analysis, and system‑level design decisionsSupport and challenge external contractors and subcontractors on technical deliveryAssist with reliability analysis and system‑level simulation activitiesSupport spacecraft and payload qualification activities, including platform and component selection inputContribute to programme planning, technical reporting, and customer‑facing programme discussionsSupport integration, test campaigns, launch preparation, and in‑orbit commissioning activitiesParticipate in design reviews, manufacturing oversight, qualification reviews, and progress reportingEssential Skills & ExperienceMaster’s or PhD in Engineering (e.g. Satellite Communications, Telecommunications, Electronics, or Digital Systems)8–10 years’ experience in satellite or space systems engineeringStrong background in satellite communications and payload architectures across LEO/MEO/GEO/HEO missionsExperience with phased array antenna systems and digital beamformingKnowledge of digital regenerative payloads and onboard processing architecturesExperience with satellite system design, HW/SW integration, and space communications architecturesFamiliarity with inter-satellite links and advanced payload conceptsExperience in space qualification processes for complex systemsUnderstanding of TT&C systems, satellite operations, and payload operationsExperience with orbital analysis tools and systems modelling (e.g. STK or equivalent)Ability to work within multidisciplinary and international engineering teamsEligibility to work in Switzerland (Swiss or EU citizenship, or valid Swiss work permit required)Desirable ExperiencePrevious involvement in ESA, NASA, or similar space agency programmesExperience with satellite operations environments, including TT&C, network management, and payload operationsExposure to end-to‑end satellite programme lifecycles from concept through to in‑orbit operationsEligibilitySwiss or EU citizenship, or valid Swiss work permit requiredWhat’s on OfferOpportunity to work on advanced satellite communications and space payload systemsEnd-to‑end involvement across system design, integration, testing, and in‑orbit operationsExposure to complex international space programmes and multidisciplinary engineering teamsHigh‑impact technical role shaping next‑generation satellite architecturesCollaborative R&D environment focused on innovation in space communications systemsTT #J-18808-Ljbffr
