RF Front-End Engineer, MEO

Role Description

MEO100 is the next generation of SES’s Medium Earth Orbit (MEO) satellite constellation. It will provide secure connectivity services to governmental entities, private companies, and commercial customers, while delivering high-speed broadband internet to eliminate connectivity dead zones. 

We are seeking a dynamic and visionary leader to join our rapidly growing aerospace team. To accelerate schedules, reduce costs, and guarantee quality, SES is internalising a critical segment of the supply chain: the final integration of partner satellite platforms with SES’s software-defined payload, all within a state-of-the-art manufacturing and test facility. 

You will contribute to the development of next-generation non-geostationary satellite orbit (NGSO) communication payloads. We are seeking a highly skilled engineer to contribute to the development and qualification of the Transmit and Receive RF Front-End Subsystems for a Ka-band Direct Radiating Antenna (DRA) payload. The role focuses on GaN and GaAs-based RF electronics, with thousands of front-end units per satellite, requiring a strong emphasis on design for manufacturing, repeatability, and reliability. You will be responsible for subsystem performance, industrialization, and integration across the satellite lifecycle. 

As a Senior Engineer, RF Front-End, MEO, you will be in charge of:

  • Ensure compatibility with digital beamforming ASICs based subsystem and antenna architecture. 
• Hardware Development & Qualification 
  • Lead the development and qualification of space-grade RF front-end modules based on GaN (Tx) and GaAs (Rx) technologies. 
  • Oversee design reviews, performance trade-offs, and compliance with space environmental constraints (thermal, radiation, EMC, mechanical). 
  • Define and validate test plans for RF performance, reliability, and environmental qualification. 
• Design for Manufacturing (DfM) 
  • Drive industrialization of front-end modules to support \ high-volume production (thousands of units per satellite). 
  • Collaborate with suppliers and manufacturing teams to optimize for yield, cost, and repeatability. 
  • Implement design practices that support automated assembly, test, and screening. 
• Supplier Management 
  • Manage external suppliers for RF front-end components, including technical oversight, schedule tracking, and quality assurance. 
  • Review and approve design documentation, test results, and qualification reports. 
• Integration & Verification 
  • Support payload-level integration and test campaigns, including: 
    • RF chain validation 
    • Functional testing of Tx/Rx modules 
    • Troubleshooting and anomaly resolution during AIT and in-orbit commissioning 
• Cross-functional Collaboration 
  • Interface with system engineering, antenna, digital, thermal, and mechanical teams to ensure subsystem compatibility. 
  • Contribute to payload-level budgets and system performance optimization. 
• Documentation & Reporting 
  • Prepare technical documentation, compliance matrices, and customer deliverables. 
  • Present technical status and findings to internal leadership and external stakeholders. 

YOUR PROFILE

• Master’s degree or Ph.D. in Electrical Engineering, Computer Engineering, or related discipline. 
• 10+ years of electronic equipment design experience, preferably in the space sector and/or involving high frequency electronics.

• Strong background in RF front-end design and integration for Ka-band satellite payloads. 
• Electronic Space Hardware: Strong background in the development, integration, and qualification of electronic hardware for space applications, including compliance with thermal, mechanical, radiation, and EMC constraints. 
• Design for Manufacturing 
• Proven experience in high-volume RF hardware development, including yield optimization, test automation, and industrialization. 
• Knowledge of PCB layout, packaging, and thermal management for spaceborne RF electronics. 
• Tools & Analysis 
• Proficiency in RF simulation and analysis tools (e.g., ADS, HFSS, CST, MATLAB, Altium). 
• Experience with RF test equipment and automated test setups. 
• Soft Skills 
• Strong leadership and ownership mindset. 
• Excellent communication and coordination skills across multidisciplinary teams. 
• Analytical thinking and problem-solving capabilities in complex system environments. 

Other requirements

• The candidate must be eligible for a “SECRET” security clearance, in accordance with the “loi modifiée du 15 juin 2004 relative à la classification des pièces et aux habilitations de sécurité”, as well as EU/ESA/NATO equivalents
