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 Keplers 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.

Key Responsibilities:
  • Lead payload systems engineering activities throughout the mission lifecycle from concept through integration test launch and commissioning.
  • Serve as the primary technical interface between customers payload suppliers spacecraft engineering teams and program stakeholders.
  • Define manage and verify payload requirements interfaces and integration plans.
  • Coordinate payload accommodation across mechanical electrical thermal software RF and operational interfaces.
  • Review payload documentation including requirements interface control documents (ICDs) verification plans test procedures and operational concepts.
  • Perform mission and systems analysis to assess payload impacts on spacecraft resources including power thermal data handling pointing storage and communications.
  • Support payload integration spacecraft-level testing verification anomaly resolution and launch readiness activities in collaboration with AIT and V&V teams.
  • Identify technical risks resolve integration issues and ensure alignment between customer expectations and spacecraft capabilities.
  • Support payload commissioning and early mission operations as required.
  • Mentor junior engineers and contribute to the continued development of payload systems engineering practices.
