- Must be legally eligible to work in Canada. - Must be capable of obtaining the required security clearance. - English proficiency is required. French is considered an asset. - Strong hands-on experience with spacecraft Command & Data Handling (C&DH) systems is required.
About the Role
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.
Key Responsibilities
- 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.
Required Qualifications
- 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: - SpaceWire - 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.
Preferred Qualifications
- 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.
