Tasks summary:
Architecture Concept & Requirements
- Translate missionâlevel ÎV, 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, PowerâProcessing Units (PPU), propellant feed & storage, and control electronics.
- Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.
Detailed Design
- Perform systemâlevel power, thermal, and mass budget analyses; produce tradeâoff 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, faultâprotection).
- Define propellant handling hardware (tanks, valves, feedâlines, interconnects) and develop contamination control procedures.
- Negotiate ICDs and interface agreements with external thruster vendors and component suppliers.
Modeling & Simulation
- Support or Develop 1âD/3âD plume models and perform reliability prediction.
Software & Control
- Define command and telemetry interfaces for EP & healthâmonitoring 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 tradeâstudy 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 spacecraftâlevel EP tests.
- Oversee hardwareâinâtheâloop (HIL) and thrustâstand testing, including thrustâcalibration, specific impulse measurement, pulseâmodulation, 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
Configuration, Documentation & Standards Management
- Author and maintain client's 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/TRRâŚetc.).
- Support Technology RoadâMapping & Innovation.
Launch-Site, On-Orbit & Operations Support
- Provide realâtime EP support during launch, earlyâorbit checkout, and routine stationâkeeping.
- Support onâorbit checkout procedures, thruster test campaigns, and contingency recovery plans.
- Support SOOH development and associated operator training.
Required Qualifications:
¡ 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
