Are you an electronics/optoelectronics engineer looking for an exciting opportunity to work on cutting-edge technologies? The Centre for Quantum Technologies (CQT) at the National University of Singapore (NUS) has an opening for a research associate to join our team in developing quantum light sources. In this role, you will play a critical part in advancing the field of quantum experiments.

As a research associate at CQT, your primary responsibility will be to work on the electronics and software for generating and modulating light sources. These light sources are crucial for conducting quantum experiments and pushing the boundaries of our understanding in this field. Additionally, you will also assist with the electrical engineering aspects of the group’s projects, ensuring the smooth operation of our research activities.

Here are some of the key areas you will be involved in:

1. Designing biasing and control circuits for avalanche photodiodes (APDs): APDs are essential components for detecting photons in many quantum experiments. You will have the opportunity to design circuits that optimize the performance of APDs and contribute to the accuracy of our measurements.

2. Developing and implementing electronics for modulating the current and voltage of laser diodes and other opto-electronic components: Precision control of these components is crucial for controlling the characteristics of the quantum light sources. Your expertise in electronics will play a vital role in achieving the desired experimental outcomes.

3. Designing drivers for temperature stabilization using sheet heaters, thermoelectric coolers (TECs), and PID control loops: Temperature stability is essential for the reliable operation of opto-electronic devices. By designing effective drivers, you will contribute to the precision and repeatability of our experiments.

4. Designing sensor circuits for opto-electronic devices: Sensor circuits play a crucial role in capturing and interpreting the data from opto-electronic devices. Your knowledge of circuit design will be instrumental in ensuring accurate data acquisition.

5. Developing high pulse rate drivers for laser diodes: Certain experiments require laser diodes with high pulse rates. Your expertise in designing high-performance drivers will enable us to push the limits of what can be achieved in these experiments.

As a qualified candidate, you should possess the following qualifications:

– A Bachelor’s or Master’s degree in Electrical/Electronics/Computer engineering or related fields.
– 2-4 years of experience in designing and developing custom electronic circuits.
– Hands-on experience in programming Field-Programmable Gate Arrays (FPGAs) using Verilog/VHDL.
– Basic skills in programming microcontrollers and writing simple software to control optoelectronics and custom PCBs.
– Designing custom PCBs with complete end-to-end ownership, including schematics, routing and layout, partial/complete assembly of components, and testing.
– Prior knowledge of System-on-Chip (SoC) would be a plus.
– A fast learner who is self-motivated and capable of independently performing duties of an electronics engineer without extensive monitoring.
– Good communication skills for effective collaboration with stakeholders both inside and outside the team.

Join us at CQT and be a part of the exciting world of quantum technologies. As a research associate, you will have the opportunity to contribute to groundbreaking discoveries and be at the forefront of shaping the future of this field.
