Principal EPS System Engineer

Electrical Power System (EPS) Design Engineer to support the design, detailed analysis, verification, and integration of electrical power subsystems (solar arrays, power conditioning units, batteries, distribution, and regulation) for our current and next-generation remote sensing and telecommunications satellites. The incumbent works in close collaboration with multidisciplinary Payload and Bus teams. Produce system requirements and electrical schematics.

Draft interface control documents (ICDs) and design descriptions.

Detailed

Design & Analysis Size solar arrays, power conditioning units, battery assemblies, and power distribution units. Develop and validate electrical models for different satellite modes, as well as FMECA analyses, fault detection, etc. Develop and maintain DC models, load balancing, thermal-power coupling models, and survivability analyses (eclipse, SHM, fault tolerance).

Present technical status, risk analyses, and comparative study results to program management. Develop/maintain power models for mission analyses (station keeping, de-orbiting). Draft verification plans, test matrices, and EPS test procedures.

Support ground test and integration campaigns (TCT, TVAC, EMI/EMC). Analyze test data, close anomalies, and update databases. Provide support for flight software (FSW) integration.

Technical





Leadership & Mentoring Serve as technical liaison with external clients, partners, and suppliers. Participate in continuous improvement initiatives. Contribute to MDA's knowledge base, process improvements, and standard development.

Configuration

Management, Documentation Ensure all artifacts, analyses, software, deliverables, and documents are version-controlled.

Launch

Site, In-Orbit & Operations Support Technical support to SatOps teams for satellite performance monitoring. update databases and capitalize on lessons learned (REX). Analyze telemetry and generate performance reports. Support SOOH development and operator training.

Degree: B.Sc. in electrical, aerospace, or physics engineering with 15+ years of experience in EPS system design on LEO/MEO platforms. In-depth knowledge of bus subsystems and their interactions. Solid writing skills and a solid understanding of space engineering fundamentals. "Hands-on" profile: capable of supporting integration, testing, and troubleshooting processes.

Ability to work autonomously with little supervision. Ability to break down complex problems into basic elements to solve them through analysis, analogy, or creativity. Excellent written and oral communication skills in English (contact with clients outside Quebec and drafting of deliverables in English). #
