Job description

PsiQuantum'smission is to build the first useful quantum computers-machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.

Our architecture and approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industry-including partners like GlobalFoundries-we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdon'tfeel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024,PsiQuantumannounced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining-and that now is the time to scale.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies-including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical-to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shift-and a path to mastering challenges that cannot be solvedany other way. The potential is enormous, and we have a clearpathto make it real.

Job Summary:

The Senior Subsystem Validation Engineer will be responsible for developing and implementing the methods and technics to validate and enhance the performance of various electro-optical subsystems.

Responsibilities:

• Review of Sub-system design including integration of optics, electronics, firmware, software and thermal design.
• Designing and building laboratory setups comprised of light sources, detector, switches; function generators, oscilloscopes, etc.
• Developing software scripts for data collection and data analysis
• Developing software scrips and algorithms to perform data analysis and extract key performance parameters.
• Design and run experiment to validate design functionality of subsystems.
• Writing validation plan for the characterization of new sub-system designs

Experience/Qualifications:

• Bachelor's degree in engineering or physical science with 6+ years of industry experience.
• At least 5 years of experience validating and testing optical systems.
• Experience working with optical and/or electrical test equipment such as power meters, optical backscatter reflectometers (OBR), optical spectrum analyzer (OSA), Oscilloscopes, function generators (AWG), vector network analyzer (VNA).
• Experience with high-speed electro-optical devices and test equipment, such us electro-optical modulator, RF detector, pulsed lasers, optical sampling oscilloscope.
• Experience developing test methods and optimization, tuning/calibration algorithms.
• Ability to understanding and write scripts to communicate and control instruments.
• Experience with python is preferred.
• Familiarity with programming CPUs to interface with FPGA's is a plus.
