Role overview:
We are seeking an experienced Electrical Power System Engineer to support the concept, detailed design, analysis, verification and integration of electrical power subsystems (solar arrays, power-conditioning units, batteries, distribution & regulation) for our current and next-generation remote sensing and communications satellites. The role works closely with payload, bus, thermal, structural and mission-systems multidisciplinary teams responsible for delivering high-performance, reliable EPS solutions to commercial, government, and defense customers.
Tasks summary:
Architecture Concept & Requirements
• Define EPS architecture (generation, storage, distribution) that satisfies mission power budget, mass, volume and reliability constraints.
• Perform trade-studies (e.g., solar cell type, battery chemistry, regulator topology).
• Generate system requirements, functional flow block diagrams.
• Develop the Interface Control Documents (ICD) and Design Description.
• Perform requirement management and maintain bidirectional traceability throughout the program life cycle.
Detailed Design & Analysis
• Size solar arrays, power-conditioning units, battery packs, and power distribution units.
• Build and validate high-fidelity electrical models for satellite modes, FMECA, Fault detection…
• Conduct & maintain power budget models, load-flow, thermal-power coupling, and survivability analyses (e.g., eclipse, safe-mode, fault-tolerant).
Cross‑Functional Coordination, Stakeholder & Program Interaction
• Present technical status, risk analyses, and trade‑study results to senior management.
• Interface with spacecraft bus teams (power, thermal, structure, avionics).
• Develop/maintain high-fidelity power models for mission analysis (e.g., orbit raising, station-keeping, de-orbit).
• Develop tools for power efficiency & optimisation for the satellite.
• Support B&P (Phase 0 & pre-phase A).
Integration & Verification (IVV)
• Author verification plans, test matrices, and validation procedures for unit & EPS subsystem tests.
• Support ground-test & integration campaigns, fueling, thermal vacuum, EMI/EMC, and spacecraft-level integration.
• Analyse test data, close out anomalies, and update design baselines.
• 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 Client's knowledge‑base, process enhancements, and standards development.
Configuration, Documentation & Standards Management
• Maintain design and safety standards.
• 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 engineering support during launch, on‑orbit commissioning, anomaly investigations and contingency operations.
• Support SOOH development and associated operator trainings.
Required Qualifications:
• B.Sc. in Electrical Engineering, Aerospace or Physics with 8 + years of EPS system design experience on LEO/MEO platforms.
• Deep knowledge of spacecraft bus subsystems and their interactions.
• Experience with power‑electronics design and power management 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).
