System Calibration Engineer [Remote]

Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world-changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.

By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.

PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier-1 semiconductor fabs such as GlobalFoundries where we leverage high-volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.

In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry-transforming results.

Quantum computing is not just an evolution of the decades-old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.

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

Job Summary:

At PsiQuantum we are developing and testing prototype modules which will scale into a datacenter-sized, fault-tolerant quantum computer. Once integrated into a final system, these modules and sub-systems need to be calibrated regularly to ensure we are producing single photons and entangled states that enable our quantum computation architecture. The System Calibration Engineer will be responsible for analyzing the performance of calibrations and overseeing their implementation in our control software. This role will involve working across a diverse set of engineering teams. Technically, the System Calibration Engineer will work with a broad set of technologies such as RF electronics, active photonics, lasers, cryostats, analog mixed-signal hardware, embedded systems, complex data acquisition systems, and quantum modules.

Responsibilities:

• Perform implementation analyses of calibrations to identify necessary hardware and firmware requirements.
• Develop timing models of calibrations and calibration routines and integrate into system-level timing budgets.
• Work closely with software engineers to implement calibrations and calibration routines in our control software.
• Support the aggregation and organization of all information required to calibrate the system from across the company.
• Collaborate with validation teams to prototype new calibration approaches and integrate mature sub-system and quantum self-tests into calibration routines.

Experience/Qualifications:

• M.S. or PhD in Electrical Engineering, Optical Engineering, Computer Engineering, Physics, or a related discipline.
• Demonstrated ability to work as an individual contributor on systems involving the integration of optical and electronic hardware, firmware, software, and data acquisition infrastructure.
• Demonstrated experience with some of the following:
  • Active photonics, RF engineering, hardware design
  • Optics, lasers, quantum computation, experimental control software
  • Embedded systems, firmware, RTL, signal processing
• Experience working on cross-functional engineering teams.
• Experience documenting projects, processes, or hardware designs.
• Experience with developing data analysis and experimental control software in python or a similar scripting language.
• Proven team player with an ability to work effectively across departments, sites, time zones.
• 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.
