Role overview:

MDA is seeking a 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 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).
- 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.

Launch-Site, On-Orbit & Operations Support

- Support on‑orbit checkout procedures, thruster test campaigns, and contingency recovery plans.
- Support SOOH development and associated operator

Required Qualifications:

- Sc. in Electrical Engineering, Aerospace, or Physics with 10+years of electrical propulsion engineering experience on LEO/MEO platforms.
- Solid knowledge of EP thruster families and their performance characteristics.
- Experience with propellant storage & feed‑system design (tanks, valves, micro‑valves).
