Senior Experimental Systems Engineer

Quantum computing holds the promise of humanitys 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 worldchanging 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 todays 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 Tier1 semiconductor fabs such as GlobalFoundries where we leverage highvolume 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 dont 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 governmentfunded projects to support the buildout of our first Quantum Data Centers and utilityscale quantum computers in Brisbane Australia and Chicago Illinois. Both projects are backed by nations that understand quantum computings potential impact and the need to scale this technology to unlock that potential. And we wont just be building the hardware but also the fault tolerant quantum applications that will provide industrytransforming results.

Quantum computing is not just an evolution of the decadesold 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.

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

Job Summary

PsiQuantum is opening a new laboratory in Brisbane Australia to focus on the validation and highperformance operationand related methodologyof our quantum photonic systems. We are looking for an experienced motivated researcher to lead the experimental efforts within the laboratory. The successful candidate will be responsible for building and leading a focused team that will design and execute experiments to validate and calibrate quantum computer subsystems to faulttolerant levels and beyond at high cadence. They will identify physical processes that limit photonic quantum performance and feedback new understandings to improve designs and operations of future generation of quantum hardware and new generations of validation methodologies. They will collaborate broadly with design and engineering teams across all of PsiQuantums technical disciplines including optics quantum optics photonics electronics cryogenics quantum architecture and software to understand system performance and inform engineering models.

Responsibilities

• Lead a team of scientists and engineers to design and execute experiments to optimize and quantify integrated photonic quantum computer systems performance at high cadence.
• Work with system design teams to define and document validation objectives and test plans. Manage equipment time and people resources to maximize the value of experimental efforts.
• Develop validation calibration selftest and control procedures for novel quantum photonic systems extending capabilities beyond current stateoftheart.
• 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 clearly to internal and external stakeholders.

Experience/Qualifications

• PhD in Experimental Quantum Physics Photonic/Electrical Engineering or a related field
• 5 years of experience postdegree and a demonstrated track record of delivering high quality research outcomes. Supervisorial experience is preferred.
• Demonstrated expertise in the design and of complex quantum experiments in a crossfunctional environment.
• Broad technical knowledge with ability to dive deep into required technical areas of our systems including hardware software controls precision measurement photonics and quantum information.
• Software development for instrumentation controls test equipment and data analysis.
• 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 PsiQuantums mission and vision for quantum computing with an ability to contribute within a fastpaced startup environment consistent with PsiQuantums values of communication collaboration respect results and challenge.
