We are seeking an experienced Satellite Command & Data-Handling (C&DH) System Engineer to support the design, integration, verification, and operation of onboard command, control, and data-management functions for current and next-generation remote sensing and communications satellite programs.

In this role, you will contribute to the C&DH functional architecture, drive technical trade studies, support system integration and verification, and provide technical leadership throughout the spacecraft lifecycle.

• →Translate mission-level requirements into C&DH functional and non-functional requirements.
• →Develop and maintain system requirements, Interface Control Documents (ICDs), and system descriptions.
• →Maintain bidirectional requirements traceability throughout the project lifecycle.
• →Support cybersecurity and resilience considerations within C&DH system design.
• →Lead detailed design activities involving:
  • →Onboard processors
  • →Spacecraft data buses
  • →Memory subsystems
  • →I/O interfaces
• →Support software architecture activities, including command sequencing, telemetry packetization, health monitoring, and FDIR.
• →Support Satellite Reference Database development and validation.
• →Define uplink command formats, downlink telemetry structures, and ground-segment data-handling interfaces.
• →Collaborate with Flight Software (FSW), TT&C/PDT, and Ground Segment teams to ensure end-to-end data integrity.
• →Develop verification plans, test matrices, and validation procedures for unit, subsystem, and spacecraft-level C&DH testing.
• →Execute functional testing, bus-protocol compliance testing, and SIL/HIL campaigns.
• →Lead anomaly investigations, root-cause analysis, and corrective-action activities.
• →Support spacecraft launch preparation, early-orbit checkout, and on-orbit operations.
• →Analyze on-orbit telemetry and support updates to operational parameters as required.
• →Support SOOH development and operator training.
• →Contribute to technical standards, process improvements, technology roadmaps, and engineering knowledge bases.
• →Support major design reviews, including SRR, PDR, CDR, MRR, and TRR.
• →Mentor junior engineers and serve as a technical liaison with customers, partners, and vendors.
