POWER ELECTRONICS (SATELLITE) ENGINEER

The Electrical Power System (EPS) is a critical subsystem in a satellite, responsible for managing power generation, conditioning and distribution on board.  The satellite obtains power from the solar panels and stores any excess power in a battery for use in the absence of sun.  Power is conditioned and distributed to various subsystems when required.  Protections are designed into the circuits to safeguard against failures.

You will be working with power engineers in the team to design power control and distribution circuits, and to optimise solar panels and battery size.  You will be involved in the full development cycle from system requirements, design specifications, prototyping and implementation to integration and test.

We are looking for highly motivated individuals with technical aptitude, who are good at working with power electronics design and hardware.  You must be able to work as a team, posses critical thinking skills and have excellent communications skills.

Requirements

-  Possess at least a good Bachelor's or Masters degree in Electrical and/or Electronic Engineering from a
   reputable university.  Specialisation in power electronics will be an advantage.

-  Strong interest in design, development and test of power electronics, with good working knowledge
   and practical experience in some of the following areas:

•  Principles of power conditioning and distribution
• Power electronics fault protection designs
• High efficiency DC-DC power conversion
• Electromagnetic compatibility for power circuits and grounding schemes
• PCB design and layout of power circuits
• Thermal management for power electronics

-  Fresh graduates are welcomed to apply.

DYNAMICS & CONTROL (SATELLITE) ENGINEER

The satellite uses a suite of sensors (e.g. like rate sensors, sun sensors, magnetometers) as well as actuators (e.g. like reaction wheels, magnetic torquers) to carry out sensing, estimation of attitude, and dynamic control of the spacecraft in space.  Propulsion is also used to provide orbit correction of the satellite.

You will be working with the team of control engineers to carry out design of conditioning circuit, integration and calibration of these sensors and actuators, on ground as well as in space.  You will be involved in the design and implementation of the control scheme with these sensors and actuators, as well as the development of Hardware-In-Loop-Simultation setup.  You will also be working on indigenous development of sensors.

We are looking for highly motivated individuals who have experience working with sensors and actuators, able to design hardware circuitry for these sensors and actuators and possess background in control engineering.

Requirements

-  Strong interest and working knowledge in some of the following areas:
