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.
