Hiring: Senior Engineer, Payload Systems, meoSphere Company: SES Satellites Location: Long Beach, CA Job Posted Time: 2026-09-10 13:44:03 Employment Type: Full-time Target Skills & Keywords : Aerospace Engineering, C++, MATLAB, Python, Security Clearance, Segment, Systems Engineering About the job Required Skills: •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. •This position is ideal for an engineer with strong analytical skills, hands-on simulation experience, and the ability to bridge payload, bus, and full system-level design. •Design payload for satellite systems, including key subsystems such as communication, networking, power, and navigation. •Support design trades involving payload capacity, system mass, power optimization, spectral resources, and overall mission-level performance. •Analyse mission requirements and translate them into technical specifications, system-level requirements, and engineering constraints. •Conduct trade-off analyses to define optimal system configurations aligned with mission and service objectives. •Optimise the performance of satellite systems by maximising payload efficiency, minimising satellite mass and volume, and improving power use and duty cycles. Qualifications: •Degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, Telecommunications, Physics, or a related field. •In-depth knowledge of satellite subsystems, particularly payloads, RF systems, and spacecraft platforms. •Hands‑on experience in system modelling, simulation, and performance assessment. •Proficiency in Python, MATLAB, and/or C++ for simulation, analysis, and tool development. •Solid analytical and problem‑solving skills, with the ability to interpret complex system interactions. •Knowledge of model‑based system engineering (MBSE) tools or standards. •Operational familiarity with digital payloads, phased arrays, and advanced communication system architectures. •Eligibility for ESA/EU/NATO/National SECRET personnel security clearances. Candidates must be prepared to undergo a security clearance procedure, as this position may require holding such clearance, is considered an asset. •Willing to work at least 60% onsite from office •Able to travel nationally & internationally Compensation: •$110,400 - $151,800 / year Interested candidates, please apply directly through the job posting on company's career page or try via AI auto apply on this platform.
