About the role
Tasks summary:
Architecture Concept & Requirements
- 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 Design
- Perform system‑level power, thermal, and mass budget analyses; produce trade‑off matrices (thrust vs. power vs. propellant mass, reliability vs. complexity). - 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. - Negotiate ICDs and interface agreements with external thruster vendors and component suppliers. - Support or Develop 1‑D/3‑D plume models and perform reliability prediction.
Modeling & Simulation
Software & Control
- Define 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 Interaction
- Communicate technical status, risk assessments and trade‑study results to senior management and/or customers or partners. - Negotiate and manage ICDs with platform subsystems and supplier teams. - Support B&P (Phase 0 & pre-phase A).
Integration & Verification (IVV)
- 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 & Mentorship
- Mentor, guide junior engineers and interns. - Act as technical liaison with customers, partners and external vendors - Act as Continuous Improvement stakeholder - Contribute to MDA’s knowledge‑base, process enhancements, and standards development.
Configuration, Documentation & Standards Management
- Author 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. - Support design reviews (SRR, PDR, CDR, MRR/TRR…etc.). - Support Technology Road‑Mapping & Innovation.
Launch-Site, On-Orbit & Operations Support
- Provide real‑time EP support during launch, early‑orbit checkout, and routine station‑keeping. - Support on‑orbit checkout procedures, thruster test campaigns, and contingency recovery plans. - Support SOOH development and associated operator training. - B.Sc. in Electrical Engineering, Aerospace, or Physics with 8+ years of electrical propulsion engineering experience on LEO/MEO platforms. - Strong knowledge of EP thruster families and their performance characteristics. - Experience with propellant storage & feed‑system design (tanks, valves, micro‑valves). - 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. - Experience with Confluence and JIRA. - Demonstrated capability to efficiently work with little to no 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). - Support the Spacecraft operations team in critical phases.
