Job summary

The Satellite C&DH System Engineer will own the functional architecture, design, and integration of command and data-handling systems for satellite programs. Responsibilities include managing requirements, leading detailed design of on-board processors, and supporting integration, verification, and on-orbit operations.

Job details

Role overview: Our client is seeking a Satellite C&DH System Engineer to support and/or design, integrate, verify, and support the on‑board command, control and data management functions for current and next‑generation remote sensing & communications satellite programs. The role will own the C&DH functional architecture, drive trade‑studies, and may provide technical authority throughout the spacecraft life‑cycle. Tasks summary: Architecture Concept & Requirements Translate mission‑level requirements into C&DH functional and non‑functional specifications. Produce System Requirements, Interface Control (ICDs), and Description documents. Perform requirement management and maintain bidirectional traceability throughout the project lifecycle. Collaborate with cyber‑security to embed resilience and security by design, ECU. Design & Development Lead detailed design of on‑board processors, data‑buses (SpaceWire, MIL‑1553, CAN, Ethernet), memory subsystems, and I/O interfaces. Support software architecture: command sequencing, telemetry packetization, health‑monitoring, services, fault‑detection‑isolation‑recovery (FDIR). Support Satellite Reference Database development and validation Cross‑Functional Coordination, Stakeholder & Program Interaction Communicate technical status, risk assessments and trade‑study results to senior management and/or customers or partners. Work with FSW teams to define RTOS, APIs, task scheduling, real‑time operating system configuration, services usage. Define uplink command formatting, downlink telemetry packet structures, and ground‑segment data‑handling interfaces (mission‑control servers, data‑archiving pipelines). Coordinate with the TT&C/PDT engineering and Ground Segment ICDs to ensure end‑to‑end data integrity. Support B&P (Phase 0 & pre-phase A). Integration & Verification (IVV) • Develop verification plans, test matrices, and validation procedures for unit, subsystem, and spacecraft level C&DH tests. • Execute functional tests, bus‑protocol compliance, SIL and HIL campaigns. • Manage anomaly investigations, root‑cause analysis, and corrective‑action implementation. Technical Leadership & Mentorship Mentor, guide junior engineers and interns. Act as technical liaison with customers, partners and external vendors Act as Continuous Improvement stakeholder Contribute to our client’s knowledge‑base, process enhancements, and standards. Configuration, Documentation & Standards Management Author and maintain C&DH standards (bus protocols, data‑format conventions, redundancy policies). Ensure all artefacts, analysis and documentations are version controlled in PLM environment. Support design reviews (SRR, PDR, CDR, MRR/TRR…etc.). Support Technology Road‑Mapping & Innovation On‑Orbit & Operations Support Support launch‑pre‑launch and early‑orbit checkout, validate satellite functions, HK and nominal operation Support and analyse on‑orbit telemetry, update filter parameters as needed. • Support SOOH development and associated operator trainings Required Qualifications: B.Sc. in Electrical Engineering, Aerospace or related field with 8+ years of C&DH engineering experience on LEO/MEO/GEO platforms. Deep knowledge of spacecraft data‑bus standards: SpaceWire, MIL‑1553, CAN‑A, Ethernet, CCSDS packet telemetry/command and PUS services. Knowledge in processor, FPGA, firmware and embedded Strong understanding of aerospace system engineering fundamentals, space environment and orbit mechanics. Hands-on individual who can support systems integration processes and capability to test systems and resolve problems. • Experience with Confluence and JIRA. Demonstrated capability to efficiently work with little supervision. Ability to distill complex problems to fundamentals to solve with analysis, similarity, or creativity. • Demonstrate excellent written and oral communication skills in English; knowledge of French will be considered an asset (Contact with clients outside Quebec and work on deliverables in English).
