The Role

The Payload Systems Engineer is responsible for designing advanced payloads for satellite systems across all orbits.

Key Responsibilities

• Design advanced communication payloads for satellite systems across all orbits (LEO, MEO, GEO)
• Contribute to the design, analysis, integration, and validation of satellite systems for next‑generation missions
• Work across payload design, system performance analysis, assembly, integration and testing, and mission operations
• Support design trades involving payload capacity, system mass, power optimization, spectral resources, and overall mission-level performance
• Work closely with software, mechanical, thermal, and electrical engineering to optimize the satellite resources
• Analyze mission requirements and translate them into technical specifications, system-level requirements, and engineering constraints
• Optimize the performance of satellite systems by maximizing payload efficiency, minimizing satellite mass and volume, and improving power use and duty cycles
• Build and execute simulations and models to evaluate payload performance under various operating and environmental conditions
• Support Assembly, Integration, and Test (AIT) activities including test plans, procedures, troubleshooting, performance validation, and verification strategies to validate systems and payload performance
• Support major reviews (SRR, PDR, CDR, MRR, TRR)
• Engage directly with hardware suppliers and evaluate hardware for payload architecture
