- 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.
- Bachelor's degree in Electrical Engineering, Aerospace Engineering, or a related field.
- 8+ years of C&DH engineering experience on LEO, MEO, and/or GEO satellite platforms.
- Deep knowledge of spacecraft data-bus and communication standards, including:
- Space Wire
- MIL-STD-1553
- CAN
- Ethernet
- CCSDS packet telemetry and command
- PUS services
- Knowledge of processors, FPGA, firmware, and embedded systems.
- Strong understanding of aerospace systems engineering fundamentals, space environment, and orbit mechanics.
- Hands-on experience supporting systems integration, testing, troubleshooting, and problem resolution.
- Experience with Confluence and JIRA.
- Ability to work independently with minimal supervision.
- Strong analytical and problem-solving skills, with the ability to break down complex technical problems into fundamental components.
- Excellent written and verbal communication skills in English.
- Experience supporting end-to-end spacecraft C&DH development and integration.
- Experience with spacecraft commissioning, early-orbit operations, and on-orbit telemetry analysis.
- Experience with FDIR, command sequencing, telemetry processing, and spacecraft health monitoring.
- Experience with SIL/HIL testing and spacecraft bus-protocol compliance verification.
- French language proficiency.
- Experience supporting satellite programs through the full lifecycle, from early concept and design through launch and on-orbit operations.
