R&D Photonics and Microwave Electronics Engineer

At PsiQuantum, we are on a mission to build the world''s first large-scale, commercially useful, 1 million-plus qubit quantum computer, powered by breakthroughs in silicon photonics and quantum architecture. We were founded in 2016 by the world''s foremost experts in photonic quantum computing and have assembled a world class team dedicated to bringing the world-changing benefits of quantum computing into reality.Quantum computing is anticipated to unlock the solutions to otherwise impossible computational tasks, with impact across science, technology and business. With applications across climate, healthcare, energy, finance, agriculture, transportation, materials design and more, quantum computing will tackle some of the most urgent practical challenges we face, as well as deliver entirely new industries.Our team is working across the full stack of quantum computing, from hardware design, manufacturing and packaging through to quantum architecture and quantum algorithms. We''re a highly integrated, collaborative team and love tackling problems than span across interfaces.PsiQuantum is uniquely positioned to deliver on the promise of quantum computing. We have already demonstrated that it''s possible to manufacture core quantum components using the standard and scalable manufacturing processes of a world-leading semiconductor fab.There''s more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!Job Summary:PsiQuantum is seeking an experimental physicist/engineer to develop modulators, switches, and other active photonic components for the world''s first fault-tolerant quantum computer. The candidate will be expected, independently and with minimum direction, to develop, construct, and validate novel measurement techniques for materials and devices research, develop theoretically valid models of device behavior, and work closely with design and simulation teams to characterize high-speed quantum photonic devices and circuits.Experience/Qualifications:The candidate should have experimental/hands-on expertise (MS/PhD or equivalent industry research experience) in some subset of the following areas:Integrated photonicsCharacterization of high-speed photonic devices, circuits, and subsystems (eg.modulators, photodetectors, transmitters, and receivers).High-speed electronicsCharacterization of high-speed electronic circuits and transmission lines (eg.modulator drivers, detector amplifiers, and high-speed traces).Free-space laser opticsExperience in advanced free space optical characterization (eg. nonlinear optics, ellipsometry, Raman spectroscopy, near-field scanning optical microscopy, etc.).Ideal Qualifications:It would be very useful if the candidate has some of these skills too:Scientific programmingPython and/or Matlab for equipment control and automation, and data analysis.Mathematica or equivalent for symbolic algebra.High-speed PCB design and layout.Strong data analysis skillsAnalyzing large, noisy datasets, and drawing robust conclusions in the presence of noise, nonlinearity, and hysteresis is a major part of the job.Cryogenic/vacuum system experienceExperience with construction and/or use of high-vacuum systems and/or liquid helium cryostats.Superior verbal and written communication skills.Solid theoretical background in microwave electronics, optics, photonics, and semiconductor/device physics.PsiQuantum provides equal employment opportunity for all applicants and employees.
