Position Status: Contingent Upon Program Award As a Senior Satellite Systems Designer / Engineer focused on Payload Management, you will serve as a key technical leader responsible for coordinating, integrating, and managing payload-related engineering activities across a mission with multiple payload providers. You will act as the primary systems engineering interface between internal teams, external payload suppliers, customers, and satellite bus stakeholders to ensure payload
requirements, interfaces, deliverables, test plans, and operational concepts are clearly defined, aligned, and executed. This role requires strong systems engineering judgment, practical experience with payload-level integration and planning, and the ability to build trusted customer and supplier relationships while guiding external stakeholders toward Kepler’s engineering standards, mission
requirements, and verification expectations. You will help ensure that payload designs, documentation, test campaigns, and operational concepts integrate safely and effectively into the broader satellite system. The ideal candidate has first-hand experience with one or more payload domains such as optical payloads, RF or SIGINT payloads, radar systems, or related mission instrumentation. Success in this role requires the ability to translate payload capabilities and constraints into mission-level scenarios, CONOPS , coverage analysis, test plans, and system budgets including power, thermal, data, and operational timelines. \n Key
