Role overview: We are seeking a System Engineer to perform design, integration, verification, and operational support of TT&C;/PDT subsystems for current and next-generation remote sensing and communications satellites. The role will interface with spacecraft payload teams, ground-segment developers, and mission-operations teams to ensure reliable command delivery, high-fidelity telemetry acquisition, and robust data handling throughout the satellite life-cycle. Tasks summary: Architecture Concept & Requirements
• Define TT&C;/PDT functional architecture (command generation, uplink, telemetry downlink, on‑board data handling, RF front‑end).
• Conduct trade‑studies for modulation schemes, coding, frequency plans, ranging and link budgets.
• 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. Design & Development
• Lead detailed design of hardware (TT&C; transceiver, RF front‑ends, antenna‑pointing) and software (command sequencer, telemetry parser, health‑monitoring).
• Perform link‑budget analysis, RF simulation (e.g., STK, Matlab), and error‑budget budgeting.
• Verify compliance with CCSDS, ECSS, ITU, and regulatory standards.
• Support Satellite Reference Database development and validation Cross‑Functional Coordination, Stakeholder & Program Interaction
• Present technical status, risk analyses, and trade‑study results to senior management.
• Negotiate and maintain ICDs and interface agreements with internal & external suppliers.
• Support B&P; (Phase 0 & pre-Phase A). Integration & Verification (IVV)
• Develop test plans, procedures, and verification matrices for unit, subsystem, and spacecraft‑level TT&C; tests.
• Execute RF link testing, BER, command latency, and telemetry integrity verification.
• Manage anomaly investigation, root‑cause analysis,



and corrective actions. 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 client’s knowledge‑base, process enhancements, and standards. Configuration, Documentation & Standards Management
• Ensure all artefacts, analysis, software, deliverables and documentations are version controlled in PLM workplace.
• 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 command uplink, telemetry acquisition, and on‑board software hand‑over.
• Provide real‑time C&T; support during nominal and contingency operations.
• Maintain ground‑segment configuration (gateways, mission control servers, monitoring dashboards).
• Support SOOH development and associated operator trainings. Required

Qualifications:
• B.
Sc. in Electrical Engineering, Aerospace or related field with 8+ years of TT&C;/PDT System design experience on LEO/MEO/GEO platforms.
• Strong knowledge of CCSDS TM/TC packet standards, ECSS telemetry & command protocols, PUS services and ITU frequency regulations.
• Proficiency in RF link-budget analysis, S-band/X-band/Ka-band modem architecture.
• 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).
