PsiQuantum is on a mission to build the world’s first utility-scale, 1 million-plus qubit quantum computer, powered by breakthroughs in silicon photonics and quantum architecture. We were founded in 2015 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. By harnessing the laws of quantum physics, quantum computers are expected to dramatically outperform even the most powerful existing (or future) supercomputers and offer the potential to enable extraordinary advances across a broad range of applications including climate, energy, healthcare, finance, agriculture, transportation, materials design, and more, as well as deliver entirely new industries.

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.

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 group and love tackling problems than span across interfaces.

There’s more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!

Job Summary:

We are looking for an energetic, motivated research engineer/physicist who will be responsible for the design and execution of experiments for the world’s first fault-tolerant quantum computer. The candidate will collaborate across quantum information, optics, electronics, cryogenics, and software disciplines to develop and validate quantum systems. The successful candidate will interface broadly with PsiQuantum’s engineering teams to ensure integrated systems are executed economically, by driving test requirements and objectives.

Responsibilities:

• Lead the design and execution of experiments to deliver scientific data and validate optical quantum computer systems performance.
• Work with design teams to define and document the validation objectives and ensure that the system design supports testing requirements.
• Interface broadly with engineering teams to understand the needs each component has for testing and validation to evaluate their performance in an integrated system.
• Develop calibration, self-test, and control procedures for novel quantum photonic systems. Define requirements for the software and electronics teams to implement procedures and manage data.
• Analyze, reduce, and deliver experimental data. Work with other engineering teams to ensure that the data informs engineering models for system performance.
• Debug complex systems and work with other engineering teams to conduct failure analysis and resolve design or manufacturing issues as appropriate.
• Communicate experimental outcomes broadly to internal stakeholders.

Experience/Qualifications:

• S. level (Ph. D. preferred) or equivalent experience in Electrical Engineering, experimental Physics, or a related field.
• Demonstrated ability to design and execute complex experiments or engineering tests in a cross-functional environment.
• Broad technical knowledge with ability to dive deep into required technical areas of our systems including hardware, software, controls, precision measurement, and photonics.
• Software development for instrumentation, controls, and test equipment (python preferred).
• Demonstrated experience with some, or all, of the following preferred:
  • Quantum optics, optics, integrated optics, silicon photonics
  • Quantum information concepts
  • Quantum state tomography
  • Cryogenic systems
  • Mixed-signal, analog, RF electronics design and test
  • FPGA programming
• Proven team player with an ability to work effectively across departments, sites, time zones.
• Ability to work independently with limited direction and own responsibility for delivering validation objectives.
• Excellent verbal and written communication skills with an ability to communicate effectively to a variety of audiences including senior leadership and technical experts.
• Demonstrated interest in PsiQuantum’s mission and vision for quantum computing, with an ability to contribute within a fast-paced start-up environment consistent with PsiQuantum’s values of communication, collaboration, respect, results, and challenge.
