Satellite Electrical Propulsion System

Engineer to define, design, analyse, integrate, and verify electric propulsion (EP) subsystems (thrusters, power‑processing units, feed‑systems, and control electronics) for current and next‑generation remote sensing and communications satellites. The role will bridge spacecraft electrical power architecture, thermal‑management, and mission‑performance requirements, and may act as the technical authority for EP on multiple programs.Translate mission‑level ΔV, thrust, lifetime, and reliability goals into EP system requirements (performance, power, mass, contamination, EMI).Produce System Requirements, Interface Control Documents (ICDs), and Description documents for thruster assemblies, Power‑Processing Units (PPU), propellant feed & storage, and control electronics.Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.Detailed DesignPerform system‑level power, thermal,



and mass budget analyses

• Lead detailed mechanical/electrical design of thruster mounting, heater/thermal control, and PPU (converter, regulator, fault‑protection).Define propellant handling hardware (tanks, valves, feed‑lines, interconnects) and develop contamination control procedures.Software &

• ControlDefine command and telemetry interfaces for EP & health‑monitoring telemetry.Work with FSW teams to develop thrust profile generation, and fault detection isolation recovery (FDIR) algorithms.Cross‑Functional Coordination, Stakeholder &

• Program InteractionCommunicate technical status, risk assessments and trade‑study results to senior management and/or customers or partners.Develop verification plans, test matrices, and validation procedures for unit, subsystem, and spacecraft‑level EP tests.Oversee hardware‑in‑the‑loop (HIL) and thrust‑stand testing, including thrust‑calibration, specific impulse measurement, pulse‑modulation, and lifetime cycling.Technical Leadership &

• MentorshipMentor, guide junior engineers and interns.Act as technical liaison with customers, partners and external vendorsAct as Continuous Improvement stakeholderContribute to MDA’s knowledge‑base, process enhancements, and standards development.Configuration, Documentation &





• Standards ManagementAuthor and maintain MDA EP standards (thruster qualification, PPU design, contamination limits).Ensure all artefacts, analysis, software, deliverables and documentations are version controlled in PLM environment.Launch-Site, On-Orbit &

• Operations SupportSupport on‑orbit checkout procedures, thruster test campaigns, and contingency recovery plans.Support SOOH development and associated operatorRequired Qualifications:Sc. in Electrical Engineering, Aerospace, or Physics with 5+years of electrical propulsion engineering experience on LEO/MEO platforms.Strong knowledge of EP thruster families and their performance characteristics.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.Demonstrated capability to efficiently work with little to no supervisionAbility 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).security clearance at the reliability status Controlled Goods Program (CGP) .An equal chance employer prizing diversity, integrity and collaboration, we are committed to growing MDA’s and Canada’s leadership in this next golden age.Extended healthcare and flexible drug plansdental and vision benefitsdisability income protectionlife insurancegroup retirement savings plansan employee and family assistance program.
