Payload


Firmware Engineer

(3 positions)

The Payload Team is looking to hire three (3) Firmware Engineers to work on the development of embedded firmware for the CNP-TEPC instrument. The CNP-TEPC is the primary science instrument on the NEUDOSE CubeSat and will help us to understand the type and amount of radiation that astronauts are exposed to during mission to the International Space Station. The successful applicants should have the ability to work effectively in a group development environment, problem-solve effectively, and have the desire to persistently drive projects to successful completion. Since development on the CNP-TEPC instrument is nearing completion, this is your opportunity to work on the first McMaster instrument to go to space!

Main Tasks and Responsibilities
  • Development of digital pulse processing algorithms (e.g. Trapezoidal, Gaussian, and Moving Average filters)
  • Development of control algorithms (e.g. PID control) to analyze the error between a measured value and a setpoint and to ensure the system remains within limits. Example projects include:
    • Controller for a high voltage power supply to automatically and slowly (~5-10 V/s) ramp up/ramp down the output voltage to/from a predetermined setpoint.
    • Controller to adjust the output of a high voltage power supply as a function of the measured temperature
    • Controller to safely turn off a high voltage power supply when excess current draw is detected (e.g. during a short)
  • Development of communication protocols (e.g. CAN bus, SPI, UART, I2C)
  • Development of firmware for programmable devices (e.g. FPGA)
  • Simulation and hardware-in-loop (HIL) testing of firmware
Requirements
  • Enrolment in Electrical & Computer Engineering, Computing and Software Engineering, or Computer Science
  • Familiar with microprocessors, microcontrollers, FPGAs, or other programmable devices
Preferences
  • Knowledge of emulator and debugging systems
  • Knowledge of Matlab and Simulink
  • Knowledge of Xilinx ISE Design Suite and Xilinx System Generator

Instrument Scientist

(3 positions)

The Payload Team is looking to hire three (3) Instrument Scientists to work on development and testing of the CNP-TEPC instrument. The CNP-TEPC is the primary science instrument on the NEUDOSE CubeSat and will help us to understand the type and amount of radiation that astronauts are exposed to during mission to the International Space Station.

Since development on the CNP-TEPC instrument is nearing completion, this is your opportunity to work on the first McMaster instrument to go to space!

Main Tasks and Responsibilities

The Instrument Scientists will help with testing, characterizing, and simulating various subsystem of the CNP-TEPC instrument. Examples of systems to be tested include:

  • temperature and pressure fluctuations of the instrument pressure vessel
  • gain variations as a function of high voltage bias, temperature, and pressure
  • count rate sensitivity against various threshold parameters

The Instrument Scientists will also develop the protocol that will be used for commissioning the CNP-TEPC instrument once the NEUDOSE CubeSat has been launched into orbit.

Requirements
  • Enrolment in Bachelor, Master, or Doctor of Science degree. Alternatively, Bachelor of Engineering or Bachelor of Biomedical Engineering students may be considered
Preferences
  • General knowledge of the systems used to readout a radiation detector (e.g. preamplifiers, amplifiers, analog-to-digital converts, multi-channel analyzers, and digital processors)
