We believe quantum computing will change everything. It will have the power to transform the foundations of giant industries that rely on intensive computation. PsiQuantum is on a mission to build the world’s first useful quantum computer, capable of delivering these transformative results. We know that means it will need 1 million qubits, error correction, 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 is uniquely positioned to deliver on the promise of quantum computing years earlier than our competitors. Our architecture is based on photonics which gives us the ability to produce our components using existing high-volume semiconductor manufacturing processes, the same processes that are today producing billions of chips for telecom and consumer electronics applications. Since photons don’t feel heat, we can take advantage of existing cryogenic cooling systems, the kind that have been operating at facilities like the Stanford Linear Accelerator (SLAC). And because photons are in fact light, they can move between subsystems at tremendous speed using standard fiber connectivity.

Our team is building a utility scale quantum computer and the software tools needed to build fault tolerant quantum applications. We’re a highly motivated and collaborative group focused on a singular goal - building the world’s first useful quantum computer on the fastest path possible.

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

Job Summary:

PsiQuantum’s applications team is uniquely focused on algorithms in the fault tolerant regime and is very tightly integrated with quantum architecture development. Within that team, the role of a quantum applications software engineer is to design, build and deploy tools which drive the development of quantum applications for solving the world’s most pressing problems. As a crucial member within the team, a quantum application software engineer’s job is to work closely with quantum applications architects and engineers to develop software toolkits and workflows, without which the team could not do their job. Such tools include (but are not limited to): quantum simulators, quantum resource estimators, quantum circuit compilation, and domain-specific quantum application integration. This work takes quantum algorithms from concept to reality, may involve close collaboration with external partners on specific use cases, and directly enables the discovery of both new quantum application use-cases and novel algorithmic techniques.

Responsibilities:

  • Lead the design, development, and deployment of quantum applications software tools to support both internal and external users.
  • Maintain, service and upgrade a high-quality codebase supported by a fast and reliable simulation infrastructure.
  • Work closely with internal and external partners and other members of the quantum applications team to design, implement and analyze quantum algorithms for real-world use cases.
  • Assist with full system analysis to evaluate and optimize resource requirements for fault tolerant computations.
  • Assist with the optimization of quantum algorithms at the subroutine, circuit, and compiled gate-set level.

Experience/Qualifications:

  • Graduate degree in Physics, Math, or Computer Science or equivalent required (MSc or PhD).
  • Practical experience in quantum computing, programming quantum applications, or quantum circuit compilation.
  • 5+ years professional experience programming and releasing production code in Python, C++, or similar languages.
  • Experience with quantum algorithms or compiling in the regime of fault tolerant gates preferred.
  • Experience with deployment of code in distributed environments, cloud application development, and RESTful API-driven architectures.
  • A results-driven “doer”, preferably with experience in a high-throughput, rapid-delivery work environment.
  • A problem solver, with an analytical mindset.
  • Proven team player with an ability to work effectively across departments, sites, and time zones.
  • Ability to work independently and contribute in fast-moving start-up environment.
