Staff Spacecraft Systems Engineer – Electronics provides technical leadership in the development, integration, verification, and lifecycle management of complex aerospace systems. This role is responsible for translating customer requirements, mission objectives, and operational concepts into system architectures, technical requirements, and engineering solutions that enable successful mission execution.

• Lead development, analysis, allocation, and management of system and subsystem requirements throughout the product lifecycle.
• Responsible for systems engineering of new electronics subsystems for Cesium Astro satellites.
• Collaborate with technical design leads to bring new spacecraft electronics products to life, integrating requirements across multiple satellites and missions to drive design implementation.
• Communicate technical needs across the spacecraft team, using data from flight operations to drive requirement evolution in future design cycles.
• Analyze customer, mission, and system‑level requirements and decompose them into clear, verifiable subsystem requirements.
• Ensure subsystem requirements maintain end‑to‑end traceability to customer requirements, system architecture, and Concept of Operations (CONOPS).
• Translate customer requirements and operational concepts into technical requirements, system architectures, and engineering solutions.
• Lead system architecture development, technical trade studies, and engineering analyses to evaluate design alternatives and optimize system performance.
• Collaborate with systems, software, hardware, electrical, mechanical, manufacturing, and integration teams to ensure requirements are complete, feasible, and technically sound.
• Define and manage hardware, software, electrical, mechanical, thermal, and data interfaces across system elements.
• Support requirements management, configuration management, baseline control, and engineering change activities throughout the development lifecycle.
• Identify technical risks, requirement gaps, ambiguities, and integration challenges early in the design process and develop effective mitigation strategies.

• Develop system verification and validation strategies aligned with customer requirements, system architecture, and program objectives.
• Define verification approaches including verification methods (test, analysis, demonstration, and inspection), verification levels, acceptance criteria, and required evidence.
• Identify verification configurations including hardware setups, software loads, firmware versions, and test environments required to support verification activities.
• Lead development and maintenance of verification documentation, including verification cross‑reference matrices (VCRM), requirements traceability matrices, and compliance evidence packages.
• Partner with Integration & Test teams to plan, coordinate, and execute system integration, qualification, environmental, and functional verification activities.
• Evaluate verification results, support technical issue resolution, and drive closure of verification gaps.
• Support technical reviews, design certification activities, and program milestones.
