About the Role

We are seeking a Senior Photonic Engineer – Experimentalist to participate in designing, developing and experimentally validating cutting-edge photonic systems. Your primary focus will be working with integrated photonics, and precise characterization of the performance of complex photonic chips with several types of high-speed integrated electro-optic elements.

Responsibilities

Design, build and upgrade complex optical laboratory experiments to characterize the performance of photonic integrated chips with electro-optic elements, using continuous-wave and pulsed laser light.
Perform precise optical measurements of PICs with networks of fast integrated electro-optic modulators; troubleshoot and benchmark opto-electronic systems for stability, noise reduction, and performance optimization, with attention to properties including switching speed, stability, crosstalk, polarization dependence, etc.
Implement and maintain optical phase locks and related frequency/phase stabilization; contribute to the development and assessment of new phase-locking and calibration protocols.
Closely collaborate with PIC development, electrical, mechanical, and software engineering teams to ensure successful module integration.
Generate detailed technical documentation, including design specifications, test procedures, characterization reports, and operational manuals.

Requirements

Demonstrated working knowledge of common laboratory RF and opto-electronic equipment (e.g. oscilloscope, signal generator, spectrum analyzer, photodiodes); the ability to build and troubleshoot complex optical experiments in a laboratory setting.
Demonstrated understanding of optical phase-locking techniques, strategies to characterize phase noise and polarization noise in optical fibres and on complex photonic chips, and a conceptual understanding of balanced homodyne detection.
A solid understanding of basic RF electronics, opto-electronic detector & electro-optic modulator concepts.
Python or similar for data acquisition and analysis.
Proven ability to build mathematical models of physical systems utilizing both analytical and numerical tools.
M.Sc./Ph.D. degree in Quantum Optics, Photonics, AMO, Electrical Engineering or a closely related field.
Laboratory research experience in academia or industry.
Prior work experience in quantum computing (particularly in optical quantum computing); with thin-film lithium niobate modulators; with co-packaged optical systems.
The ability to independently design, build, and troubleshoot complex optical experiments and clearly communicate measurement-derived insights; the ability to rapidly absorb complex, proprietary architectures and master new experimental frameworks.
Experience writing Python scripts for instrument control, hardware interfacing, and automated data acquisition.
Expertise in balanced homodyne detection (c.w. or pulsed), laser noise characterization techniques (phase/frequency, RIN), advanced laser interferometry (Pound-Drever-Hall locking, locking/control theory), optical pulse shaping with IQ modulators and AWGs.
Ph.D. in Quantum Optics, Photonics, AMO, Electrical Engineering or a closely related field.
