We offer full relocation support, including immigration assistance. You may work remotely at first while your immigration process is being completed. Long-term, the role will transition to onsite work in Montreal.
Role overview:
We are seeking a Satellite Bus System Engineer to design structural, thermal, power distribution, attitude control, propulsion, CD&H, TT&C/PDT, FSW and interface architecture that supports payloads and mission-operations for current and next-generation remote sensing and communications satellites. The role leads the definition, design, integration, verification and on-orbit support of the platform subsystems, ensuring compliance to mission requirements and company best-practice processes.
Tasks summary:
Architecture Concept & Requirements
• Translate mission‑level requirements (CONOPs, mass, volume, power, envelope, pointing, lifetime, redundancy, reliability…etc.) into system requirements and allocate them to platform subsystems (structures, TCS, EPS, GNC, PROP, C&DH, TT&C/PDT, FSW).
• Develop the Platform Architecture Description Document, Interface Control Documents (ICD) and Design Description.
• Perform requirement management and maintain bidirectional traceability throughout the program life cycle.
Concept Trade & Feasibility
• Lead trade studies for structural approach, thermal control concepts (MLI, heat pipes, radiators…etc.), power generation options (e.g. solar array & battery technologies).
Detailed Design
• Oversee detailed design of all major subsystems (structures, TCS, EPS, PROP, C&DH, C&T, GNC, payload interfaces).
• Conduct failure‑mode‑effects‑analysis (FMEA) in support to FDIR, fault‑tree analysis and reliability & availability predictions.
• Ensure compliance with mission requirement and payload specifics.
• Maintain platform level performance budgets
• Support FSW and Satellite Reference Database developments
Cross‑Functional Coordination, Stakeholder & Program Interaction
• Present technical status, risk analyses, and trade‑study results to senior management.
• Negotiate and maintain ICDs with payload and all platform subsystems.
• Support to DC & RF harness design, Platform and Payload layout.
• Support B&P (Phase 0 & pre-phase A).
Integration & Verification (IVV)
• Author verification plans, test matrices, and validation procedures for unit, subsystem, and platform level tests.
• Coordinate, supervise or support:
o Structural vibration, acoustic & shock testing
o TCT & Thermal vacuum testing
o Power distribution functional test
o Closed‑loop test on avionic testbed
• Support FSW integration
Technical Leadership & Mentorship
• Mentor, guide, lead a multidisciplinary team of junior or intermediate system engineers & interns
• Act as technical liaison with customers, partners and external vendors
• Act as Continuous Improvement stakeholder
• Contribute to company's knowledge‑base, process enhancements, and standards development.
Configuration, Documentation & Standards Management
• Maintain platform‑wide standards (structural margin, thermal‑control, power‑bus architecture, redundancy philosophy…etc.).
• Ensure all artefacts, analysis, software, documentations and deliverables are version controlled in PLM environment.
• Support design reviews (SRR, PDR, CDR, MRR/TRR…etc.).
• Support Technology Road‑Mapping & Innovation
Launch‑Site, On‑Orbit & Operations Support
• Support launch‑site interface checklists with LVI responsible engineer, pre‑launch checkout procedures, and early‑orbit checkout scripts.
• Provide real‑time platform engineering support during launch, on‑orbit commissioning, anomaly investigations and contingency operations.
• Support SOOH development and associated operator training.
Required Qualifications:
· B.Sc. in Electrical Engineering, Aerospace or Physics with 10 + years of system design experience on LEO/MEO/GEO platforms.
· Deep knowledge of spacecraft bus subsystems and their interactions.
· Experience with power‑electronics design and high‑precision attitude‑control hardware.
· Strong understanding of aerospace system engineering fundamentals
· 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).
