Job Description

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 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 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).
