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 setting.
- 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).
