Aufgaben

• 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.
• 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 FDIR algorithms.

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.
