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. Modeling & Simulation • Support or Develop 1‑D/3‑D plume models and perform reliability prediction. 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 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/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. 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
