As support to a European space company we are looking for a Power Electronics System Engineer

Activities

Our customer is a European system house, specialised in development and implementation of solutions for aerospace. You will be working on-site, responsible for:

• Requirements/architecture analysis at electronic function and electronics board level
• Analysis of design (parts stress analysis, worst case analysis, failure modes and criticality analysis, radiation analysis, etc); Stability analysis of control loops; Assessment of EMC performances of the power subsystems, equipments, boards
• Specification of the electronics design physical implementation
• Review of design documentation; laboratory & prototype testing
• Preparation of test procedures for the design characterization and manufacturing acceptance; specification of necessary test benches; board level testing; test reports
• Preparation of technical proposals answering customer specifications;
• Technical lead of engineers in close cooperation with the project manager

  • DC/DC power converter design in classical topologies (buck, boost, flyback, forward, push-pull, full bridge, half bridge, SMART, current doubler, etc. including control loop and stability analysis.)
  • Equipments to distribute protected supply lines to spacecraft power users: latching current limiters, foldback current limiters, heater drivers, pyrotechnics line drivers
  • Power control units to manage the power from the primary power source (solar arrays) to the distribution bus and also to charge / discharge the secondary power source (batteries)
  • Solar array regulators with the different regulation techniques
  • Battery management electronics, battery charge and discharge controllers.
  • Motor driving electronics: stepper motors, linear motors, brushless motors, torquer motors, etc.), and actuators driving electronics
  • High voltage power electronics, AC distribution, etc.
  • Design of magnetic components; EMC analysis, EMC testing
  • Digital design for the TM/TC interfaces of the power electronics
  • Analog design for the voltage, current and temperature acquisition chains related to the power electronics subsystem
• Fluency in English and German languages is mandatory
